14.2 External I/O
392
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. 391)
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. 405). 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 500 mA max 200 mW max
HIGH
4 to 5.0 V
LOW
0 to 0.5 V
GND
4.7 kΩ
TRIG OUT
4.7 kΩ
1 kΩ
5 V
1ms or greater
Trigger events occur and signals are output when the auto-ranging function
(
FUNCTION MODE F4 [Auto Setting]) ( p. 73) is used with the Memory Func-
tion. You should be aware of this if you are using the trigger output terminal
together with the auto-ranging function.
