Trigger
RF Trigger Source
The
RF Trigger Source command selects the trigger to be used for the specified measurement when RF
is the selected input. The RF trigger source can be queried and changed even while another input is
selected, but it is inactive until RF becomes the selected input.
Note the inclusion of the <measurement> parameter in the command below. Because each measurement
remembers its own Trigger Source, the command must be qualified with the measurement name. Note
that for the Swept SA measurement this is not the case; for backwards compatibility, no <measurement>
parameter is used when setting the Trigger Source for the Swept SA measurement.
