Select the Measurement Trigger Source
NOTE
An immediate trigger command over the bus will generate an
immediate trigger regardless of the trigger source.

measurement, select a trigger source from the following:
Bus

The selected pin must be configured as a Trigger Input to be used as
a trigger source (see Appendix B)
Transient
<channel>

<channel> specifies the channel.
The trigger source can only be selected using the following SCPI
commands. The front panel only displays the trigger source that is

Initiate the Measurement Trigger System
When the SAS is turned on, the trigger system is in the Idle state. In this

system returns to the Idle state. Thus, it will be necessary to initiate the
measurement system for the next triggered measurement.
