The Avtech model AV-1000-C is a 50 MHz, general purpose laboratory pulse generator providing amplitudes of 0 to ±10 V. It also includes DC offset, variable rise and fall times, exceptionally low jitter, and operating convenience.
ECL and TTL outputs (and their complements) are provided, making the AV-1000-C an ideal pulse source for both digital and analog applications, and for triggering those Avtech instruments that require an external trigger (i.e., modules and -PS units).
The front panel features simple self-explanatory controls. The output amplitude is controlled by a six-position range switch (±1, ±5 and ±10 Volt ranges) and a one-turn vernier control. 50 Ohm back-matching is provided for the ±1 and ±5 Volt ranges. A one-turn control allows the variation of the base-line or DC offset from 0 to ±10 Volts. The output stages will safely withstand any combination of front panel control settings.
The main output rise and fall times are variable from 5 ns up to 1 ms using a common five-position decade range switch and separate one-turn vernier controls. Similar arrangements control the output pulse width from 10 ns to 1.0 sec and the relative delay between the outputs and the SYNC output from ±25 ns to ±1.0 s. The delay jitter for this model is exceptionally low (≤ ±25 ps). The pulse repetition
frequency is variable from 1 Hz to 50 MHz in eight ranges.
An externally applied TTL-level pulse may also be used to control the output PRF, and in addition the unit includes a "SINGLE PULSE" push button. A double pulse mode is available and a GATE input is provided for control of the internal triggering.
