GATE function (GX 320 only)
This function is only available with “CONT”, “SWEEP” and “MODUL”.
It superimposes a stop command for the alternating MAIN OUT signal
component over the current function, piloted by a TTL input to the BNC
FREQ EXT Gate in terminal.
When the TTL signal is at the 1 logical level (5 V), the alternating
component of the MAIN OUT terminal is cut.
At 0 level it is generated freely.
The GATE has no effect on the direct component of the signal.
The command takes effect in approximately 100 ns.
