6. Interface Towards Sampling Unit
When the signals pass through an optical barrier between the
processor system and the rest of the electronics, the Sampling
Unit's F1 terminal controls the relays, choosing the load and at-
tenuator values on the Load Board.
7. Scope Output
The scope output is based on a measuring Transformer L1,
mounted on the Load Board. The measuring Transformer is ter-
minated with a 50 ohms resistance R31.
8. Foot Switch
The output foot switch is based on a relay (K11), and is used in
triggering the ESU being tested.
