Function/Sweep Generators


Manufacturer: Wavetek
Model: 180


Generator is a source of precise sine, triangle and square waveforms. Frequency of the waveforms is manually and remotely variable from 0.1 Hz to 2 MHz.

The generator can repetitively sweep from one frequency to a higher frequency, with controllable rate and range of sweep. Amplitude of the waveforms is variable from 10V peak-to-peak into 50 ohm down to30 mV p-p. DC reference of the waveform can be offset positively and negatively.


Output Signals Sine, triangle, square, TTL pulse, ramp and DC.

Operating Instructions

  1. Allow a 1/2 hour warm up when output is critical.
  2. Manual Control
    1. Connect circuit to either HI or LO output.
    2. Set FREQ MULT to desired range of frequency.
    3. Adjust FREQUENCY DIAL to desired frequency.
    4. Set waveform selector to desired waveform (sine, triangle, square, DC)
    5. Adjust DC offset to 0 or positive/negative offset.
    6. Select desired amplitude using AMPLITUDE DIAL.
  3. Sweep Generator Operation
    1. Perform steps outlined above
    2. Adjust SWEEP WIDTH to desired upper frequency of the sweep.
    3. Adjust SWEEP RATE to desired speed of the sweep.
