Output Trigger — The Model 2790 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 per-
formed. If instead, the trigger counter is set to 10 and the sample counter is set to 1, a trig-
ger will be sent after each measurement.
