Wavetek Model 183, the 5 MHz XCG/Sweep Generator, is a precision source of sine, triangle, square, positive pulse and negative pulse waveforms plus DC voltage. Frequency of the waveforms is manually and remotely variable from 100 µHz to 5 MHz. Select frequencies from 2 Hz to 5 MHz can be locked to a crystal oscillator for maximum frequency accuracy. The generator can repetitively sweep between two individually set frequencies and at a particular sweep rate. The amplitude of waveforms is continuously variable from 20V p-p, open circuit maximum, to —80 dB. DC reference of the waveforms can be offset positively and negatively. The symmetry of the waveforms is continuously adjustable from approximately 1:19 to 19:1. Varying symmetry provides variable duty cycle pulses, sawtooth and asymmetrical sine waveforms. A voltage representing generator frequency, a fixed-amplitude pulse train of that frequency, and a voltage ramp representing frequency sweep rate are provided as front panel outputs.
