Theory of Operation This section describes the 2715 circuitry. The section begins with a functional description of the major circuit blocks. This is followed by more detailed descriptions of the circuitry within each block. While reading these descriptions, refer to the corresponding diagrams in Section 9: Diagrams.
Theory of Operation A 25 Ω resistor within the RF INPUT connector assembly is placed in series with the signal path. This transforms the connector to a 75 Ω impedance for external signal connections. All RF signal connections within the 2715 (SMA and SMB connectors) have a 50 Ω impedance.
Theory of Operation What It Does The Spectrum Analyzer accepts an electrical signal as its input and displays the signal’s frequency components on a CRT. Signals are applied directly to the RF INPUT. The display of the input signal appears on the CRT as a graph where the horizontal axis is frequency and the vertical axis is amplitude. How It Works Attenuator and Low Pass Filter The Spectrum Analyzer operates as a variable bandwidth receiver.
Theory of Operation RF Mother Board Assembly The RF Mother board assembly contains a 2 GHz 2nd LO, a 2nd Converter, several gain stages, a 5 MHz resolution bandwidth filter, and a 3rd Converter. The 2nd Converter down converts the 2110 MHz 1st IF to 110 MHz. The 3rd Converter down converts the 110 MHz 2nd IF to a 10 MHz 3rd IF. This signal is routed to the Variable Resolution module.
Theory of Operation The Display Storage board is capable of storing four waveforms of 512 bytes each, four pages of text of 512 bytes each, and up to two markers. Any combination of waveforms and text may be displayed on the CRT. If any waveforms are being displayed, the text portion of the display is limited to approximately 100 characters in order to avoid flicker. Only one page of text may be displayed at any one time. The readout page is limited to approximately 100 characters.
Theory of Operation 100 MHz Reference Oscillator This is a precision, temperature controlled, quartz crystal oscillator that provides the reference around which all instrument frequency related performance revolves. It is designed for maximal frequency stability over temperature and time, with absolute frequency accuracy being secondary. The instrument firmware accounts for any frequency inaccuracy, producing a virtually perfect reference.
Theory of Operation 1st LO Buffer The 1st LO Buffer consists of a Leveled Amplifier and a Phase Gate Detector. The Leveled Amplifier provides the LO input drive for the 1st Mixer. The Phase Gate Detector logs 1st LO drift. That information is then used for frequency corrections. Sweep The Sweep board contains a microprocessor interface, horizontal sweep generator, trigger circuitry, vertical sweep (raster scan) circuitry, video processing, video line triggering, and graticule illumination.
Theory of Operation Display System The Display System consists of the Vertical Display circuit, Horizontal Display circuit, and Z Axis circuit. See Figure 3--2. The Display System has three possible display modes. The active spectrum display mode displays the incoming signal. The static spectrum display mode displays stored signals from memory. The video monitor mode displays live video signals.
Theory of Operation Circuit Description The following sections provide detailed circuit descriptions and is arranged to follow the input signal flow. While reading these descriptions, refer to the corresponding diagrams in Section 9: Diagrams. Attenuator and 1st Converter The Attenuator and 1st Converter signal path consists of the following parts: Step Attenuator H Step Attenuator H 1.8 GHz Low Pass Filter (2.2 GHz Low Pass Filter for Option 50 and Option 75) H Mixer H 4.
Theory of Operation A relay switch at the input of the Step Attenuator selects the RF input signal or the internal calibrator signal. See Figure 3--3. Since the calibrator signal comes into the Step Attenuator assembly ahead of the attenuators, it can be used to verify the accuracy of the Step Attenuator and other parameters. Selection is made through the INPUT MENU. RF IN 75 Ω Step Attenuator 1st Converter 1.8 GHz3 Attenuator 4.5 GHz RF 2110 MHz IF LO Calibrator 100 MHz/−22 dBm PREAMP 3 2.
Theory of Operation 1st Converter The 1st Converter converts the incoming RF signals to the 1st IF. Input signals are applied through the Step Attenuator and Low Pass Filter and through the 1st LO Buffer Amplifier. The 1st Converter receives the RF signal through the Low Pass Filter and a 1st LO signal from the 1st LO Buffer Amplifier. These signals combine to produce mixing products that are filtered to yield the 2110 MHz IF signal.
Theory of Operation RF Mother Board and Phase Locked 2nd LO This section contains a detailed description of the RF Mother board and Phase Locked 2nd Local Oscillator. Overview RF Mother Board Block Diagram The RF Mother board converts the 1st IF frequency to 10 MHz in two frequency conversions. The first conversion (2nd mixer) mixes the 2.11 GHz 1st IF with the 2 GHz 2nd LO to create a 110 MHz second IF. The 2 GHz LO is generated on the board and is phase locked to the 100 MHz crystal reference.
Theory of Operation The 110 MHz 2nd IF is amplified and divided along two paths. One path is through a buffer amplifier to the sweep board where the signal is available to the satellite demodulator. The second path is through a PIN attenuator which sets the gain of the module. The signal then passes through a second amplifier stage then a 110 MHz Bandpass filter. This filter has a 3 dB bandwidth of 5 MHz which sets the widest resolution bandwidth of the instrument.
Theory of Operation 110 MHz Bandpass Filter. This filter is a 5th order, shunt resonator Butterworth filter. 3rd Mixer. U665 and its associated circuitry make up the 3rd mixer. Output Amplifier. This IF amplifier consists of a common emitter transistor (Q670) with both series and parallel feedback. The 1:1 transformer (T670) provides lower output impedance for better intermodulation distortion performance. The resistive attenuator at the output is used to match the load to the variable resolution.
Theory of Operation When the FM coil is used to sweep the oscillator, the relay on the Interface board closes and couples a large capacitor (two capacitors in parallel) across the main coil. The capacitors lower the noise bandwidth of the main coil driving circuit while the FM coil is in operation. The heater provides temperature stability. The rest of the circuitry on the Interface board provides operating voltages for the two amplifiers in the 1st LO assembly.
Theory of Operation The directional coupler couples approximately --15 dBm of the amplified LO signal to the detector. The coupled signal is then amplitude detected, and the resultant DC level fed to the noninverting input of a comparator, where it is compared to a reference DC level. (The reference DC level is connected to the inverting input.) The output of the comparator then controls the active bias tending to hold the amplifier’s output at a constant level. Strobe Driver.

If the phase delay of Q1, Q2, or the tank changes, the operating frequency must also change to maintain a 0° loop phase shift. Because of this phase/frequency shift dependency, the Q of the parallel tank circuit is made as low as possible to minimize the tank phase change as the values of Lt and Ct drift.

Theory of Operation Microprocessor Interface. The Microprocessor Interface is used by the Microprocessor board to communicate with the Reference Oscillator board. An 8 bit input shift register controls the operation of the board, and an 8 bit output shift register contains frequency correction bits for indicating the Oscillator frequency.
Theory of Operation In wide spans (5.1 MHz/div or greater), the center frequency is set coarsely by setting a suitable bias current in the main coil. Fine increments of the center frequency are set by appropriate currents to the FM coil. In this mode, sweeping over the span is accomplished by summing a suitably scaled analog sweep signal with the drive to the main coil.
Theory of Operation This supply consists of VR160, U166, U174, Q170, Q674, and associated components. VR160 is a temperature compensated reference diode that defines the output voltage. U166 and Q170 constitute a buffered scaling amplifier to provide the desired --5 V output at sufficient current. C660 makes the closed loop bandwidth very low to minimize noise from the reference diode on the output.
Theory of Operation This voltage across R926 defines the feedback current to the summing junction of the operational amplifier. This circuit forces 1st LO main coil current to be proportional to the sum of the currents from the various control sources, which is described later. The normal operating current range of the main coil is from approximately 135 mA to 255 mA. Q920 is a switch that is normally conducting and consequently has no significant impact on circuit operation as described.
Theory of Operation When the FM coil driver is in use (instrument not phase locked) there are two potential signal sources summed into the driver circuit. One that is always present is induced by DAC U850A and subsequent circuits. It is steered into U821 by switch U757A, and serves to finely set the center frequency. The other is selected only in moderate spans. It is the sawtooth sweep waveform used to sweep the 1st LO over spans ranging from 50 kHz/div through 5 MHz/div.
Theory of Operation down the strobe driver amplifier in the 1st LO BUFFER module. Also, U240 serves as a count selector switch. It selects either the LFVCO signal or the 1st LO beat signal (from the PLCFC board) for counting by the microprocessor. R241 is part of a TTL to ECL level shifter, the remainder of which is located on the microprocessor board. U510B provides a lock status indicator for the inner loop so that a lock failure can interrupt the microprocessor through circuitry on the PLCFC board.
Theory of Operation This allows for 1st LO drift or user changes to the center frequency setting without having to drop and reacquire lock for every change. If Q652 is turned on by the signal UNLKIND (signifying that the inner loop is unlocked), both INCR MAIN and DCR MAIN are turned on simultaneously. This is a unique condition that the microprocessor interprets as a hardware failure in the VCO module. Summary of Outer Loop Lock Acquisition.

Theory of Operation In phase locked spans, its output is used to fine tune the VCO frequency. In either case its output passes through U852, which has an output range of 0 to +5 V. U845 sums that with an offset and provides gain so that the output of U845 ranges from --5 V to +5 V. This signal is called VCFC (L/FM) and is routed to the appropriate destination by U757A and U757D. Main Coil DAC U950A output passes through U952 and U940.
Theory of Operation This is the loop back path referred to earlier for checking the interface. This register may also be loaded with up to eight bits of parallel data for subsequent serial transfer to the microprocessor. Only three bits are used. Bits 7 and 8 are the signals (INCR MAIN and DCR MAIN) from the lock limits comparator, and bit 5 is wired to logic 1 as a board identity.

Theory of Operation 10 dB Gain Step Amplifier The 10 dB gain step stages incorporate a transformer feedback amplifier. These stages have approximately 0.5 dB of loss or 9.5 dB of gain, for a net difference of 10 dB. When the gain step is selected, the signal is routed through the amplifier for a gain of approximately 11.5 dB. A pad of approximately 1.5 dB is added to trim the gain down to 10 dB. The signal is then routed through a switch that has approximately 0.5 dB of loss.

Theory of Operation The board provides the resolution bandwidths used to fill in between filter values installed within the Variable Resolution module. The bandwidth range is 1 MHz to 1 kHz in decade steps, and 300 Hz. Each filter path consists of a switchable amplifier and bandpass filter combination. Control System Interface Bandwidth Control Identification Bit The control of the RF Options by the microprocessor is through one 8 bit shift register. Data is shifted serially in one 8 bit word.
Theory of Operation Log Amplifier The Log Amplifier system is a high performance, intermediate amplifier system that provides display laws of linear detection and logarithmic detection of the incoming signal. The log display has scale factors of 10 dB/div, 5 dB/div, and 1 dB/div. The linear mode has the ability to magnify the top portion of the waveform to enhance the measurement capability.
Theory of Operation Logarithmic Amplifier Stages The core of the logging stage is a pair of AD640s. The AD640 uses five cascaded limiting amplifiers to approximate a logarithmic response to an input signal of wide dynamic range and wide bandwidth. The two AD640s are used in a parallel/summing operation. The input signal to one AD640 is amplified by 25 dB with the CLC501.
Theory of Operation Immediately following the Video Filters is the Scale Factor amplifier. The gain of the Scale Factor amplifier can be set to 1.1, 2.2, 5.5, or 11 corresponding to 10 dB/div, 5 dB/div, 2 dB/div, or 1 dB/div. The linear function is done with the gain set to 1.1. FM Detector The AD834 (U350) is a four quadrant multiplier that is used as a quadrature detector for demodulation of FM signals. The audio output is sent to the audio amplifier selector and to the video input selector.

Theory of Operation PEAKDIS_L. In the Normal Mode this bit selects one of the two acquisition modes. Either the Max Peak, when low, or the Min/Max algorithm when high. In the Enhance Mode this bit is used in conjunction with the ACQM0 bit of Mode Control Register 2 to invoke Sample and Min Peak algorithms. See Table 3--3 below. HLF/FLL_L. In the Normal Mode this bit selects one of two positions on the CRT screen to normalize the B,C--Save A display.
Theory of Operation POS1. This bit, along with the HLF/FLL_L bit (called POS0 on the schematics) in Mode Control Register 1, determines the position on the CRT for the B,C--Save A display. The Normal Mode does not use this bit. Table 3--4 gives the positions on the screen that are available when using the HLF/FLL_L and POS1 bits.

Any number of text pages may be displayed on the CRT, however the resulting display may not be readable, and will flicker severely. TEXT2. This bit, when high, places page two of the four possible readout pages on the CRT. Any number of text pages may be displayed on the CRT, however the resulting display may not be readable, and will flicker severely. TEXT1.
Theory of Operation Marker Position Registers. There are two Marker Position Registers. One register for Marker 1 and a second register for Marker 2. Marker Position Register 1 uses I/O port locations 0x0FC00 through 0x0FDFF. Marker Position Register 2 uses I/O port locations 0x0FE00 through 0x0FFFF. Each port location corresponds to a horizontal position on the screen.
Theory of Operation MKR2_LT. This signal becomes active (high) at any access to the Marker 2 port addresses (I/O port addresses 0xFE00 through 0xFFFF). This signal also causes the UPREQ signal to become active. Table 3--11 is the memory map for the Display Storage board.
Theory of Operation Control Registers. There are five control registers on the Display Storage board which are used to set the various operating modes for the board. All of the control registers are read/write registers, with the exception of the Scroll Register. The Control Register section consists several 74HCT273 latches and 74HCT541 tristate buffers, and two 74F138 decoders. Each control register is made up of a 74HCT273 latch and a 74HCT541 tristate buffer.

The PORTVEC signal becomes active, enabling one of the enable inputs on both of the decoders, U16 and U17.
Theory of Operation The comparators are contained in an LM319, U9. The top (UP) comparator determines if the summing node is greater than the 49.5 mV reference point. The bottom (DN) comparator determines is the summing node is less than the 0.0 V reference. The outputs of these two comparators, UP and DN, are fed into the Horizontal LCA. Inside the Horizontal LCA the UP and DN signals are debounced to prevent false changes in the internal counter.
Theory of Operation voltage by about one third. The signal is then passed through a diode, CR2 and an emitter follower, Q3, and then into U1, an MC10319 Flash ADC running at 2.4576 MHz. Transistor,Q3, provides the low input resistance required by the ADC. Eight bits of vertical data are output by U1 at each falling edge of the clock.
Theory of Operation At the end of a horizontal bin the contents of the Max Accumulator will be written to waveform memory. If the acquisition mode is Min Peak the same comparisons occur as in Max Peak acquisition mode, except that the Min Accumulator is used. At the end of a horizontal bin the contents of the Min Accumulator will be written to waveform memory.

Theory of Operation Offset, (HOO) R98, are provided. In addition part of U34, an analog switch, and another resistor are added in parallel to the feedback resistor of the operational amplifier to allow gain reduction while the readouts are being drawn. This will allow the waveform to extend beyond the edge of the graticule and still allow the readouts to be visible.
Theory of Operation The Error Amplifier compares the current state of the Integrator Circuity output and the current input voltage from the DAC and generates an error voltage. This error voltage is then fed into a high current buffer made up of Q4, Q5, and CR7. CR7 and R179 are used to insure that transistor Q4 is properly biased. The high current buffer is required to ensure that the capacitor in the Sample and Hold section is charged quickly.
Theory of Operation The Power up reset circuit consists of a TL7705 Power Supervisor IC. This IC monitors the +5 V supply and generates a reset signal on power up. The capacitor, C101, is used to delay the rising edge of BDRST_L for about 50 ms. This ensures that if the +5 V supply falls below 4.5 V, the BDRST_L signal will remain low for a minimum of 50 ms, and that the LCA will go through a valid reset cycle and reprogram correctly.

Theory of Operation Clock Generator The Clock Generator chip (U360) is an NEC PD71011. The purpose of this IC is to generate the clock for the Microprocessor board and synchronize the insertion of wait states into the CPU. The Clock Generator part of the IC uses a 14.7456 MHz crystal (parallel resonant) to generate the 7.3728 MHz CPU clock (14.7456 MHz ÷ 2). In addition to the CPU clock output, there is an oscillator clock output that is divided by six (÷6) using three flip flops (U240).

Interrupt Number System Connection IR5 Digital Options Board IR6 Digital Options Board IR7 Programmable Interval Timer 1 See the NEC PD71059 (or Intel 82C59) data sheets for more detailed information on the operation and programming of the Interrupt Controller.
Theory of Operation Reading from a module begins with the module requesting service through its active low request signal (FPREQ-- for the front panel, ...). This signal goes into a priority encoder (U780) on the Power Supply Secondaries, then pulls the Microprocessor board Interrupt Handler, IRQ1, high. The outputs of the priority encoder are then used to acknowledge the request for service that activates the output buffers on the module requesting service.
Theory of Operation Allowances have been made for on board programming of the EPROM devices. On board programming is done by removing J528 (and/or W528) and then supplying the appropriate timing and voltage signals to program the EPROMs through connector J550. Software Option Jumpers There are two jumpers (1 kΩ resistors) on the I/O Subsystem Status Register that can be used by the CPU to set various software options. These jumpers select the options shown in Table 3--17.
Theory of Operation The reference/period counter consists of devices U295, U380, and counter one of U470. The reference counter is fed from the 100 MHz Reference Oscillator. The IF counter consists of devices U370 and counter two of U470. The IF counter is fed from the IF input and ranges in frequency from 5 MHz to 15 MHz. The Frequency Counter Control Register (U385) contains all of the signals necessary to run and control the Frequency Counters.
Theory of Operation Hardware Interface The Microprocessor requires several signals. A brief description of these signals, by connector, is given in Table 3--18, Table 3--19, and Table 3--20.

Theory of Operation GPIB, RS- 232, Real Time Clock, NVRAM, and Gated Measurement Functions The Digital Options module provides both the RS--232 and GPIB interface and gated sweep capability. The features are: H Gated measurement functions to provide in service measurement capability H A standard IEEE 488.
Theory of Operation Real Time Clock The Real Time Clock (RTC) is an Oki Semiconductor MSM62X42BRS clock/calendar (U23). This IC uses an internal 32,768 Hz clock which is divided down to 1 Hz. This one hertz clock is then used to drive the time registers. Each time register consists of some multiple of ten of the current time (i.e. 1 sec, 10 seconds, 1 minute, 10 minutes, ..., 10 years). The time registers are also writeable allowing easy time setting.
Theory of Operation Battery Backup Circuit The battery backup circuits consist of a 2.8 V lithium battery (BT1), and two DS1210 (U16 and U17) power monitor chips. U17 supplies backup power for the RAM (U8), likewise U16 supplies the real time clock (U23). The DS1210 chips supply power from the power supply while its voltage is above 4.75 V and switches to the 3 V battery backup supply when the power supply voltage falls below 4.75 V.
Theory of Operation Video Gating Control Register There are ten video gating control registers on the Digital Option module. All of these control registers are write only registers, with the exception of misc. gating control register (address 0x210). The other nine registers contain line count and pixel count information used to control the IF gate and Display Storage acquisition. IF Gate System This system performs gating of the IF signal path at a point immediately before the VR filter.
Theory of Operation Control Signal Conditioner This circuit takes in HCMOS logic levels and produces shaped and risetime controlled control signal(s) having the characteristics required by the IF gate circuit. The IF_GATE_EN signal is first passed through CMOS inverter U6 powered from a locally regulated +5 V source to produce output voltage levels which are well defined, stable, and noise free.
Theory of Operation The tuning voltage path from the DAC to its varactor includes a temperature correction from sensor (U9). Video Detector The 45.7 MHz signal from the SAW filter is presented to the MC44301 demodulator (U16). This device passes the signal through an AGC controlled IF amplifier, then to a synchronous detector. The reference signal for the detector comes from an internal PLL.
Theory of Operation AFC Lock Control Circuitry The lock control circuitry is used to switch the AFC loop (mentioned in the downconverter description) ON or OFF as required in the course of getting the video demodulator locked onto a new TV channel. The AFC loop needs to be reset by the instrument firmware on certain occasions (such as instrument re--tuning) to assure that the demodulator is locked to the correct channel.
Theory of Operation When this voltage reaches approximately 1 V, an RS flip flop inside U460 resets and the holdoff cycle is finished. The sweep gate logic circuit is then enabled to accept another trigger and, if in the free run mode, another sweep is then started. Transistor Q574 is used to abort the sweep and initiate another holdoff. Transistor Q255 is used to choose a long or short holdoff time. A logic 1 at pin 13 of U312 turns on the transistor, diverting the available current to charge C252.
Theory of Operation The video monitor mode is generated by using the vertical sync outputs of the sync separator and HCLK to control an auxiliary sweep generator formed by U560B and its associated components. This ramp generator (U560B) provides the vertical sweep while the normal sweep circuit forms the horizontal sweep. When the video monitor mode is selected, Q522 is turned off, which lowers the sweep current, and slows the normal 5 s/div sweep to approximately 6.3 s/div.
Theory of Operation All of the control information is shifted in through four shift registers U211, U312, U610, and U520. Front Panel The Front Panel acts as an interface between the user and the instrument. These circuits translate operator actions on front panel controls into data for the microprocessor to read and execute. The Microprocessor outputs data showing current operating modes to the user through LEDs (light emitting diodes) and CRT readout. The Front Panel consists of five sections.
Theory of Operation The FPREQEN-- signal is used to enable the front panel request output buffer. If FPREQEN-- is in the inactive state, the front panel service request line to the microprocessor will always be active (always requesting service). The CLKIEN-- signal is reserved for future use. Switch Matrix The Switch Matrix consists of 59 normally open single pole, single throw switches. These switches are configured in a 6 × 11 matrix (possibility of 66 switches total).
Theory of Operation 5. Steps 2 and 4 are repeated, retriggering either the POS or ROS, until the switch has stabilized in the closed position. 6. Each single shot then times out approximately 50 ms after the last valid trigger. 7. Now the switch is released and a negative edge is presented to both the POS and the ROS. 8. This edge triggers the ROS and its output becomes active. 9. With the ROS output active and POS output inactive, the POS is held in the reset state by a NAND gate. 10.
Theory of Operation The three conditions illustrated in Figure 3--27 are as follows: 1. Switch pressed and released inside the 50 ms time of POS. 2. Switch pressed and released well after both the POS and ROS have timed out. 3. Switch pressed and released with the POS becoming inactive during the release. The debounce single shot is triggered by the rising edge of the POS and has a 1 ms pulse width.
Theory of Operation 5. After the firmware recognizes the request for service, the FPACK-- line is set low, which enables the DATAI and CLKI tristate buffers. 6. The data is then clocked out of the switch matrix shift registers. 7. After the data has been clocked out, the FPACK-- line is set high, disabling the DATAI and CLKI tristate buffers. 8. The rising edge of FPACK-- is also used to reset the request for service flip flop. 9. The board is now ready for another key press.
Theory of Operation Primary The Power Supply primary circuits consist of the AC Input circuit, a Pulse Width Modulator (PWM), an Inverter, and a Frequency Lock circuit. See Figure 3--28. AC Input. Input power is applied through an EMI line filter, a line fuse, an on/off switch, additional EMI filtering, and a full wave rectifier and storage capacitor.
Theory of Operation At power up, there is a delay until R185 charges C290 to approximately 20 V, at which time Q690 and Q691 turn on to supply power to the PWM IC. The capacitor provides drive current until the PWM output (TP293) reaches 60 V relative to special ground (TP190). Initial pulses to the MOSFET switch are narrow, but they gradually widen as C691 (between pins 4 and 14 of the PWM IC) charges. If current through R260 at the source terminal of the MOSFET switch exceeds 1.
Theory of Operation NOTE. For instruments with serial numbers B030000 or above, a dead time control (DTC) R669 has been added which will be used to set the maximum high voltage measured at the –2.75KV test point by varying the voltage at pin 1 of U260. New values for C262 and R652 have been chosen to lower the effect of the leakage current from pin 4 of U260. Any pin 4 leakage current through R652 will reduce Power Supply performance.
Theory of Operation Power Supply (Display) The Display system consists of the following: H CRT Bias H Vertical Display circuit H Horizontal Display circuit H Z Axis circuit Figure 3--29 is a block diagram of the Display Amplifier.
Theory of Operation The CRT is biased as follows: Cathode Heater Grid Accelerator Focus Astigmatism D3, D4 ave D1, D2 Geo mesh Anode TRACE ROT --2750 VDC --2750 VDC, 6.2 VRMS --2880 VCO 24 VDC --2200 to --1925 VDC 115 to 0 VDC 24 VDC 45 VDC 115 to 0 VDC 11000 VDC +30 mA to --30 mA The voltage multiplier is encapsulated in high insulation material. Both cathode and anode multipliers are AC coupled within the multiplier and have multiplication factors of --2 and +8, respectively.
Theory of Operation Horizontal Display The Horizontal Display circuit is a paraphase amplifier. Gain and DC offset (Horizontal Position) are set so the signal at the input of the paraphase amplifier swings from --1 V to +1 V. The output of the paraphase amplifier then drives the horizontal deflection plates.

Maintenance Corrective Maintenance Corrective maintenance consists of component replacement and instrument repair. Special techniques and procedures that may be required to remove and replace assemblies or components in this instrument are described here. Handling Static Sensitive Components. Most semiconductor types, both separately and in assemblies, are susceptible to damage to static charge, see Table 6--1 on Page 6--2 for voltage levels.
Maintenance Surface Mounted Components. Surface mounted components are used in this instrument. These components are mounted on pads on the circuit board, rather than through holes in the board. (In some rare instances, components may be mounted on pads around through holes.) Lead configurations of these components are shown in Figure 6--3.
Maintenance 1. Unsolder the component. Use a solder wick to remove access solder. 2. Clean the board with isopropyl alcohol. 3. Solder in the replacement. Surface mounted components are pretinned, and therefore require little solder. CAUTION. If you use a soldering iron, use one with a small tip. After applying the solder paste, touch the corner of the pad with the iron to fasten the component. Avoid touching the component with the hot soldering iron.
Maintenance Soldering Techniques NOTE. Disconnect the instrument from its power source before replacing or soldering components. Extreme caution must be used when removing or replacing components, because the instrument contains several multi layer circuit boards. Excess heat from the soldering iron and bent component leads may pull the plating out of the hole. Some circuit boards do contain leaded components. To remove the component leads, use a 15 W (or less) pencil type soldering iron.
