The external control terminals on the instrument support trigger signal input and
output.
Be sure to read p. 52 to p. 53 for external control terminal connection details.
Triggering can be controlled by applying a signal from an external trigger source
(p. 136).
This allows synchronous operation of multiple instruments by parallel triggering

(p. 209).
See "Using External Triggering"(p .136) for setting procedures and trigger signal
details.
The external signal input function can be changed to insert event marks.
