Keithley 2700 User Manual

8-18 Triggering Model 2700 Multimeter/Switch System User’s Manual
Output Trigger — The Model 2700 will send one or more output triggers. The output
trigger is applied to the Trigger Link connector on the rear panel. It can be used to trigger
an external instrument to perform an operation.
The trigger model can be configured to output a trigger after the completion of a series of
measurements, or after every measurement. For example, with the sample counter set to
10 and the trigger counter set to one, a trigger will be sent after the 10 measurements are
performed. If instead, the trigger counter is set to 10 and the sample counter is set to 1, a
trigger will be sent after each measurement.
Triggering commands
Commands for triggering are summarized in Table 8-2.

*RST Restore *RST defaults (see “Default” column of this
table). Places 2700 in the idle state.
Notes:
1. SYSTem:PRESet enables continuous initiation.*RST disables continuous initiation.
2. SYSTem:PRESet sets the trigger count to INF (infinity). *RST sets the count to 1.
