Chapter 12 External Control

You can output a signal when a trigger event occurs. This allows synchronous oper-
ation of multiple Memory HiCorders by parallel triggering (p. 226).
For the external trigger setting procedure, see "Applying Trigger with External Input
Signal (External Trigger)" (p. 127)
12.3 External Signal Output (Trigger Output)
Pulse wave is output.

• When triggering is not otherwise used, a trigger signal is output during
measurement.
A trigger signal is also output when the Auto Range function is used,
so be careful when using both Auto Range and the trigger output sig
-
nal for triggering other devices.
• When using an external trigger to synchronize multiple instruments,
make sure you set the external trigger output to [Level] on the Sys-
tem screen of the external trigger input.
