9.2 External Signal Output (Trigger Output)
206
You can output a signal when a trigger event occurs. This allows synchronous
operation of multiple instruments by parallel triggering (p. 209).
9.2 External Signal Output (Trigger Output)
Trigger output signal is output.
(TRIG.OUT)

Trigger Output Signals
Output signal Open drain output (with 5 V voltage output), active LOW

level HIGH level: 4.0 to 5.0 V, LOW level: 0 to 0.5 V
Pulse width LOW level: 100 ms or greater

The signal is output even when triggering is not enabled. When triggering is
not otherwise used, a trigger signal is output during measurement.
Signal Output Procedure
Connect the instrument's TRIG.OUT external control terminal to the exter-
nal device to be triggered.

(See the connection procedure on p. 53 )
When a trigger event occurs, a pulse wave changing from the HIGH level (4.0 to 5.0 V)
to the LOW level (0 to 0.5 V) is output from the TRIG.OUT terminal.
