TEST INSTRUMENT SAFETY WARNING Normal use of test equipment exposes you to a certain amount of danger from electrical shock because testing must sometimes b e performed where exposed voltage is present. An electrical shock causing 10 milliamps of current to pass through the heart wil l stop most human heartbeats. Voltage as low as 35 volts dc or ac rms should be considered dangerous and hazardous since it can produce a lethal current under certain conditions.

INTRODUCTION triangle waves over the 0.1Hz to 10MHz range. This encompasses subaudible, audio, ultrasonic, and RF applications. A continuously variable dc offset allows the output to be injected directly into circuits at the correct bias level. The B+K Precision Model 4017A Sweep/Function Generator is a versatile signal source which combines several functions into one unit - waveform generation, pulse generation (through variable symmetry), and frequency sweep.

For example, if the 100 kHz range is selected, the output frequency can be adjusted from 10kHz to 100kHz. FUNCTION Switch.
CONTROLS AND INDICATORS 22. GATE LED. Indicates when the frequency counter display is updated. When the 100K through 10M ranges are selected, the LED will flash 10 times per second (every 0.1 seconds). When the 10 through 10K ranges are selected, the LED will flash once every second and when the 1 range is selected, the LED will flash every 10 seconds. As the LED turns off, the display is updated. 23. Hz and KHz LED. Indicates whether the counter is reading in Hz or kHz. 17. DUTY CYCLE Switch.
Figure 1. Model 4017A Front Panel. OPERATING INSTRUCTIONS The B+K Precision Model 4017A Sweep/Function Generator is a versatile instrument, capable of producing a variety of output waveforms over a broad range of frequencies. To gain a working familiarity with the unit, it is recommended that it be connected initially to an oscilloscope, so that the effects of the various controls on the output waveforms can be observed.
OPERATING INSTRUCTIONS 7 . A superimposed DC component can be added to the output signal by engaging the DC OFFSET switch (14) to enable operation of the DC OFFSET control (5). Rotation of this control adds a positive or negative DC component to the output signal. The DC component introduced is independent of the OUTPUT LEVEL control and can be varied by ±10 volts open circuited or ±5 volts into 50 Ω. The DC Offset does not affect the TTL/CMOS output jack. The effect of DC OFFSET is shown in Fig. 3.
OPERATING INSTRUCTIONS 6. Remember that the output signal swing of the generator is limited to ±10 volts open circuited or ±5 volts into 50 Ω, and applies to the combined peak-to-peak signal and DC offset. Clipping occurs slightly above these levels. Fig. 3 illustrates the various operating conditions encountered when using the DC offset.
OPERATING INSTRUCTIONS TTL/CMOS OUTPUT 1. The end frequency of the sweep (lowest frequency) can be adjusted by rotating the SWEEP WIDTH control (16). This adjustment should generally be made after setting the starting frequency, because it is largely dependent on that setting. The TTL/CMOS output jack provides a fast rise time square wave output. Either a fixed TTL or a variable CMOS output level is available.
OPERATING INSTRUCTIONS 2. Set the starting frequency with the COARSE control. Apply a positive DC voltage to the VCG/SWEEP input jack (9) to decrease the frequency. A voltage from 0 to +10V will cause the frequency to decrease by a factor of 100 if the COARSE frequency control is set at maximum CW rotation. For example, if the starting frequency is 100kHz, applying +10V will change the output frequency to 1kHz. 3.

714-921-9095 TEST INSTRUMENT SAFETY (continued from inside front cover) 6. Some equipment with a two-wire ac power cord, including some with polarized power plugs, is the “hot chassis” type. This includes most recent television receivers and audio equipment. A plastic or wooden cabinet insulates the chassis to protect the custom er. When the cabinet is removed for servicing, a serious shock hazard exists if the chassis is touched.
