This parameter should be set to match the
equipment connected to the Trigger Input socket on
the connector panel of the analyzer.
Set it to None, if not used.
Set Trigger Input to MATRON Handswitch if the
analyzer is being used in the MATRON system.
This setting should also be used if you want to use
the Handswitch ZH-0680 for manually triggering
signal recordings.
Note: This can only be used together with
analyzers with serial numbers above 2479652
Set Trigger Input to Voltage Level if you want to
control signal recording by a voltage level
generated by external equipment. The Voltage
Level should generate at least 2 V for On and less
than 1 V for Off. The duration of the steady level
should be at least 1 s, so it can be recognised by
the analyzer
Set Trigger Input to Voltage for Monitoring if you
want to monitor the voltage at this input. This setting
can be used together with Notifications – see
section 8.4. This setting cannot be combined with
MATRON Handswitch or Voltage Level
