Chapter 1 Functions 1.
1.1 Block Diagram Signal Flow The signals to be measured enter at the input terminals and pass first to the attenuator (ATT) and preamplifier. Adjusted vertical-axis characteristics (voltage and amplitude) in accordance with the settings for input coupling, probe attenuation, V/div, and offset value are passed to the A/D converter. Voltages are converted to digital values by the A/D converter. The digital data is then processed by the data processing circuit (digital file processing, etc.).
1.2 1 Setting the Vertical and Horizontal Axes Functions Time Axis Selection of the Timebase With the default settings, sampling timing is controlled by the clock signal output from the timebase circuit of the instrument (see the Block Diagram, section 1.1). The sampling timing can be controlled by an external clock signal instead of the clock signal from the timebase circuit. An external clock signal can be input to the EXT CLOCK IN terminal on the rear panel.
1.2 Setting the Vertical and Horizontal Axes Relationship between the Time Axis Setting, Sample Rate and Record Length Changing the time axis causes corresponding changes in the sampling rate and the acquisition record length. For more detailed information, see Appendix 1. Relationship between Time Axis Setting and Sampling Mode The sampling method (sampling mode) for an input signal changes according to the time axis setting as described hereafter.
1.2 Setting the Vertical and Horizontal Axes 1 Vertical Sensitivity The V/div setting is made by setting the voltage value per division on the screen grid. The vertical sensitivity setting operates by switching to a different attenuator (attenuation rate). The setting changes in steps (1 V/div → 2 V/div → 5 V/div ...). In addition, by performing computations on the digital data acquired using the voltage sensitivity above, the waveform can be displayed at a sensitivity of 0.4 (or 0.
1.2 Setting the Vertical and Horizontal Axes Offset Voltage When observing a voltage riding on top of a predetermined voltage, an offset voltage can be applied to eliminate the predetermined voltage so that only the changes in the signal can be observed with higher voltage sensitivity. Normally, the offset voltage does not affect the cursor measurement values, automated measurement of waveform parameters, and computed values.
1.2 Setting the Vertical and Horizontal Axes 1 Probe Attenuation • The voltage and current of the circuit to be measured are not disturbed. • A signal can be input without distortion. • The measurement voltage range of the oscilloscope can be widened. A 200 MHz passive probe is supplied with the instrument. The probe enables you to select whether the input signal is attenuated to 1/10 or 1/1*.
1.3 Setting a Trigger Trigger Type There are two principal trigger types which you can use with the instrument. Simple trigger Enhanced trigger Simple Trigger → Sections 6.5 to 6.7 This is an edge trigger and the one which is used normally. Enhanced Trigger → Sections 6.8 to 6.14 This is a complex trigger. The following seven types of enhanced trigger are available. A→B(N) trigger A Delay B trigger Pattern trigger Width trigger OR Trigger Window trigger TV trigger Edge Trigger → Section 6.
1.3 Setting a Trigger 1 A Delay B Trigger (Enhanced Trigger) → Section 6.9 CH1 CH2 Trigger CH1 CH2 H L H L H L H L H L H L H L H L H L 1 µs Pattern A is True Pattern B is True When pattern A: CH1 = L, CH2 = L, Enter, When pattern B: CH1 = H, CH2 = H, Enter, Delay = 1 µs Pattern Trigger (Enhanced Trigger) → Section 6.10 Multiple trigger sources are selected, and a trigger is activated when all of the trigger conditions set for each trigger source become true or false.
1.3 Setting a Trigger The description of the figure above is as follows. If CH1 = H, CH2 = L, CH3 = X, CH4 = X, Condition = True, Time = 350 ns: (The DL1620 is not equipped with channels 3 and 4.) The trigger is activated at point B if Pulse < T. The trigger is activated at points A and C if Pulse > T. The trigger is activated at point C if T1 < PLS < T2 where Time1 = 350 ns, Time2 = 450 ns. The trigger is activated at points A, B, and D if T1
1.3 Setting a Trigger 1 Trigger Mode Auto Mode Displayed waveforms are updated each time a trigger is activated within a specified time (approximately 100 ms, referred to as the time-out period) and are updated automatically after each time-out period. Auto Level Mode Waveforms are displayed in the same way as in Auto mode if a trigger is activated within the time-out period. If no trigger is activated, the center value of the amplitude of the trigger source (section 1.
1.3 Setting a Trigger HF Rejection Set HF rejection to ON when you want to remove high frequencies exceeding 15 kHz from the trigger source. This prevents a trigger from being activated unexpectedly due to high-frequency noise. Trigger Hysteresis
1.3 Setting a Trigger 1 Trigger Delay (called the delay time) has elapsed following activation of a trigger. The range for the trigger delay setting is 0 to 4 seconds. T (Trigger Position) Delay Time Trigger Point Trigger Position The trigger position indicates which position of the waveform in the acquisition memory will actually be displayed on the screen. The trigger point refers to the point at which a trigger is activated.
1.4 Setting the Acquisition and Display Conditions Record Length The term “record length” refers to the number of data points (per channel) acquired in the acquisition memory. “Displayed record length” refers to the number of these data points that are actually displayed on the screen. (Note that sampling rate and record length will vary according to the time axis setting; see section 1.2.) It is possible to set the following record lengths.
1.4 Setting the Acquisition and Display Conditions 1 Acquisition Modes Functions When storing sampled data in the acquisition memory, it is possible to perform processing on specified data and display the resultant waveform. The following data processing methods are available. Normal Mode In this mode, sampled data are stored in the acquisition memory without processing.
1.4 Setting the Acquisition and Display Conditions Sequential Store In the real-time sampling mode, waveform data will be stored in the acquisition memory only a set number of times, and all waveforms can be displayed. This stops automatically after acquisition. The maximum acquisition count available with the feature varies depending on the record length. The range for the DL1620/DL1640 is 2 to 4000 times (for the DL1640L, it is 2 to 16000 times).
1.4 Setting the Acquisition and Display Conditions 1 History Memory depending on the record length and high-resolution mode. The oscilloscope retains all waveforms for the first N triggers; then, for each subsequent trigger, the oscilloscope overwrites the oldest stored waveform. You are free to switch the display from the current (newest) waveform to any of other N-1 waveforms in the history. The illustration below shows how data can be displayed, assuming N = 1024.
1.4 Setting the Acquisition and Display Conditions Waveform Labels → Section 8.5 You can assign an arbitrary label (up to 8 characters) to each waveform. Trigger Mark Waveform Label Scale Values Selects use of 2 waveform windows. Display Interpolation This feature selects the type of interpolation applied in areas where there are less than 500 sample points (Less than 250 points in the zoom window when zooming on the waveform using Main & Z1 & Z2) per 10 time axis divisions.
1.4 Setting the Acquisition and Display Conditions 1 X-Y Waveform Display Y plot lets you view the relationship between the signal voltages. The X-Y waveforms and normal waveforms (a waveform displayed using voltage and time axes) can be displayed simultaneously. Use of this X-Y waveform display function enables measurement of the phase angle between two sine wave signals.
1.4 Setting the Acquisition and Display Conditions If you display the “main” area (normal waveform display) together with one or both zoom windows, the main area will include vertical lines (or “zoom boxes”) indicating the zoom area (s). The center of the zoom area corresponds to the center of the zoom box.
1.5 1 Analyzing the Waveform Functions Linear Scaling It is possible to append a scaling constant A, an offset value B and a unit to the measurement value X of cursor or automated measurements. Linear scaling is useful, when applying a voltage divider ratio to the measurement values. Linear scaling is also handy when you want to your scope to automatically convert the measured voltage results into the (for example, current or temperature) measurement unit of your signal source.
1.5 Analyzing the Waveform Automated Measurements Automatic Measurement of Waveform Parameters → Section 9.2 This feature automatically measures selected waveform parameters, such as rise time and pulse width. You can select parameters separately for each channel, although you are limited to a total of 12 parameters to display. There are 27 parameters available for selection. The measurments are made for data in the acquisition memory. Statistical Processing → Section 9.
1.5 Analyzing the Waveform 1 • Statistical Processing for Each Period Statistical processing is performed from the oldest measured data of the displayed waveform. Example in which CH1 is selected as the target waveform for determining the period CH2 CH1 a b c The parameters for automated measurement are measured in each range a, b, and c, and statistical processing is performed on each automated measurement parameter in the order a, b, and c.
1.5 Analyzing the Waveform Waveform Math Addition, Subtraction, and Multiplication → Section 9.5 Addition, subtraction, and multiplication can be performed between CH1 and CH2 with Math1, and CH2 and CH3 for Math2 (or CH1 and CH2 with Math1 for the DL1620). The result is displayed as waveform Math1 or Math2 (or waveform Math1 on the DL1620). Addition and subtraction are useful for comparing signals to the standard signal, checking the signal logic, and comparing signal phases.
1.5 Analyzing the Waveform 1 Power Spectrum Display Functions FFT (Fast Fourier Transform) computation can be performed on the input signal to display its power spectrum. This is useful when you want to check the frequency distribution of the input signal. Power Spectrum Waveform Three time windows are available: a Rectangular window, a Hanning window, and a Flattop window.
1.5 Analyzing the Waveform Data Search (History Search Function) This feature can be used to search waveforms that match the specified conditions from the history memory. History Memory Search Using Zone → Section 7.7 Searches waveforms that did or did not pass through the specified area from the history memory. Waveform that was Saved Using the History Memory Function Specified Area Selected Record No.
1.5 Analyzing the Waveform 1 Serial Pattern Search waveform (64 statuses) is detected at the rising or falling edge of the channel that is specified as the clock channel or at a constant time interval. The matched pattern is displayed expanded in the zoom window.
1.5 Analyzing the Waveform • Example in which the clock channel is set to CH1 and CH1: rising, CH2: L, CH3*: H, and CH4*: L CH1 CH2 CH3* CH4* CH2 CH3* CH4* L H L L H H L L H L L H H L H L L: Low Level, H: High Level Detects this Position andDisplays the WaveformExpanded in the Zom Window * The DL1620 is not equipped with channels 3 and 4.
1.5 Analyzing the Waveform 1 Auto Scroll IM 701610-01E 1-29 Functions The zoom box scrolls automatically in a designated direction. You can stop the zoom box while checking zoomed waveforms.
1.6 Communications Ethernet Interface (Option) Saving and Loading to and from a Network Drive (FTP Client Function) → Sections 13.3, 13.4 You can save, delete, and copy waveform data, screen image data, and setting information onto the hard drives of devices on the network such as a PC or workstation running the FTP server function just as you would onto internal floppy disks, Zip disks, or PC cards.
1.6 Communications 1 Mail Transmission (SMTP Client Function) → Sections 13.6, 13.7 measurement rate. DL1620/ DL1640/ DL1640L E-mail Personal Computer Web Server Function → Section 13.12 You can use the DL1620/DL1640/DL1640L as a Web server. From the DL1620/DL1640/ DL1640L Web page you can transfer files, monitor waveform display, perform basic DL1620/DL1640/DL1640L key operations, and acquire waveform data.
1.7 Other Useful Functions Connecting a USB Keyboard (Option) You can connect a USB keyboard for entering file names, comments, and other information. In addition, the keys on the keyboard are assigned to the keys on the front panel of the DL1620/DL1640/DL1640L, which allows you to operate the DL1620/ DL1640/DL1640L in a similar fashion. (See Appendix 5.) DL1620/ DL1640/ DL1640L USB Keyborad USB connection Connecting a USB Mouse (Option)
1.7 Other Useful Functions 1 Snapshot must be stopped. Use of the snapshot function allows the currently displayed waveforms to remain temporarily on the screen without acquisition being stopped. To activate this function, just press SNAP SHOT without stopping acquisition. The currently displayed waveform will be retained. This waveform is called a snapshot waveform. The snapshot waveform is displayed separately in white making comparison between the two easier.
1.7 Other Useful Functions Displayed Data Output Functions You use these functions to print the screen image to the optional built-in printer, or an external USB printer or a network printer, to save the image data to the storage medium (internal flash memory, floppy disk, Zip disk, PC card, or network drive (Ethernet interface option)). Also, the instrument can display a thumbnail (miniature sample) of the screen data saved to the storage medium.

7.2 Acquisition Mode Explanation You can select any of three acquisition modes, as follows. The default selection is Normal. Normal The instrument writes sample data into acquisition memory without performing special processing. Envelope The instrument finds the maximum and minimum sampled values per interval of 200 MS/s (100 MS/s when the high-resolution mode is ON). It then writes these values into acquisition memory, and generates an “envelope” waveform showing max/min levels for each point.
7.2 Acquisition Mode Important Information about the Averaging Mode • Averaging mode is useful when working with repetitive waveforms. • Correct averaging is not possible if the waveform has imperfect triggering, since synchronization will be poor and the displayed waveform will be distorted. When working with this type of signal, set the trigger mode to Normal, so that the waveform display is updated only when the trigger occurs. (See section 6.1) • Roll mode display is disabled during averaging.
