Triggering

This example use an external trigger input at the External Trigger Input (D-connector) “Trig” input to trigger readings.

Resetting the module sets the data format to ASCii, sample source to TIMer and trigger source to IMMediate. The sample interval and the trigger source are changed from the reset setting.

Resetting the module also sets the trigger level to 0V and the trigger slope to positive. Trigger level and slope commands are resent to reiterate the level and slope of the trigger. In this case, the slope command is redundant.
