Triggering Measurements
You can use the data acquisition trigger system to synchronize the timing of the
voltage and current data acquisition with an external trigger source. Then use the
FETCh commands to return different calculations from the data acquired by the
measurement trigger. The following measurement trigger sources can be
selected:
SCPI triggering nomenclature
As previously explained under “Triggering Output Changes” on page 244, the ac
source uses the following sequence name and alias for the measurement trigger
system. This alias can be used instead of the sequence form.
BUS selects GPIB bus triggers.
EXTernal selects the external Trigger In BNC connector.
TTLTrg selects the signal driving the Trigger Out BNC connector.
