Operation

The switching state of a channel is indicated by the green LEDs on the selector front panel. The following table shows the relation of the relays and the LEDs for each switching state.

States

CH 1 and CH 3

CH 2 and CH 4

All open

SMU on

PGU on

PGU open

The "PGU open" state is useful if a lot of switching needs to be performed. When the switching state changes from "PGU on" to "PGU open", only the semiconductor relay switches. This reduces the amount of times the mechanical relay is switched. The semiconductor relay has a much longer switching life than the mechanical relay.
