The Я4С-90 is a dual-trace vertical amplifier plug-in for Soviet 7000-series clones. It is roughly analogous to the Tek 7A18.
Significant differences to the 7A18 include:
- has a bandwidth limiting switch like the 7A26
The input connectors are СР50-73 type.
The example in the photos is labelled in German. A version labelled in Russian also exists.
Key Specifications
| V/div | 5mV/div to 5V/div in 1-2-5 sequence |
|---|---|
| Vertical modes | I, chop, add, alt, II |
