14.2 External I/O
380
You can output a signal when a trigger event occurs.
You can also connect several instruments for parallel trigger synchronized oper-
ation.
See "Parallel Trigger Synchronization" (p. 379)
14.2.2 Trigger Output
(TRIG OUT/CAL)
Pulse wave is output.
Trigger event occurs
TRIG OUT/CAL
The TRIG OUT/CAL terminal can be used as a trigger output terminal (TRIG
OUT) or as a probe calibration output signal terminal (CAL) (p. 393). It cannot be
used for both functions at the same time.
Trigger Output Signals
Output signal Open collector output (with voltage output), active LOW
Output voltage range HIGH level: 4.0 to 5.0 V, LOW level: 0 to 0.5 V
Pulse width LOW level: 1 ms or greater
Maximum input voltage -20 to +30 V 50 mA max 200 mW max

Trigger events occur and signals are output when the auto-ranging function
(

F4 [Auto Setting]
) (p. 74) is used with the Memory Function.
You should be aware of this if you are using the trigger output terminal together
with the auto-ranging function.
