The Model LG-1 may be used as a reference with Berkeley Nucleonics pulse generators to provide a sliding pulse train. The principle of operation is as follows: A solid-state chopper in the pulse generator is connected via an external reference connector to the ramp. The ramp is sampled at periodic intervals as set by the frequency controls of the pulse generator. The pulse generator then converts the sampled voltage into tail pulses whose amplitude increases and decreases linearly. The differential linearity of the sliding pulse train will be better than ±0.1% with Model PB-4, and better than ±0.2% with Model BH-1.
The period is adjustable to either 5 or 50 sec by a front panel toggle. These periods will provide the usual range required in sliding pulse tests. However, for other applications the period may be altered by changing the internal timing capacitor. A front panel Amplitude trimmer which controls the maximum swing of the ramp also provides a fine control of the ramp period since the amplitude and period are inter-related.
