Explanation
The GS610 can input or output various signals through the BNC input/output terminal
(TRIG/SWEEP/CTRL IN/OUT) and the external input/output connector (EXT I/O) on the
rear panel. Such signals include trigger input/output signals that determine the timing of
the source and measurement, ON/OFF control signals of output relays, ON/OFF control
signals of zero generation, and comparison result output.
The BNC input/output terminal and the external input/output connector are independent.
Therefore, different roles can be assigned and used simultaneously.
BNC Input/Output Terminal
One signal can be assigned to each terminal. Multiple signals cannot be assigned.

Note
There are no settings that need to be entered on the GS610 screen for the trigger input
(TrigIn), sweep synchronization input (Sweep Start In), control input (Ctrl In), and comparison
result output (Compare) of the external input/output connector. Make connections according
to the pin assignments given above.
