The Я4С-89 is a plug-in for Soviet 7000-series clones which contains a pulse generator. It is intended for use with the sampling plugins in a similar manner to the Tek S-52 pulse generator head. It can free-run or take a 5 V external trigger signal.
The pulse outputs require an external pulse shaping cable in order to be useful. The cables contain a 50mA tunnel diode, type 1И308К.
From the top, the connectors are:
- external 5 V (TTL) trigger in
- sync output, variable level and polarity
- positive-going pulse output
- negative-going pulse output
The buttons are:
- manual trigger
- external trigger mode
- period 1/0.1/0.01 ms
- delay 25/50/100/200 ns (can be added by pressing multiple buttons)
- pulse width 0.01/0.2 μs
The rotary controls are:
- external trigger level
- period vernier
- sync output amplitude, negative-zero-positive
- delay vernier
- pulse width
then two screwdriver bias adjustments for the positive-going and negative-going pulse outputs.
The connectors are СР50-73 type, which are almost compatible with BNC connectors but the latch is a tight fit and the centre contact can be unreliable.
