Triggered Measurements

Use the measurement trigger system to synchronize the acquisition of measurements with either a BUS or
internal trigger. You can trigger voltage and current measurements on the main output (output 1) and on
the DVM. An internal trigger synchronizes the acquisition to a signal condition. Use FETCh commands
to return different calculations from the data acquired by the measurement system. Briefly, to make a
triggered measurement:
1
Select a sweep interval and sample size
2
Set up the trigger levels
3
Setting the output 2 voltage and current
4
Select the trigger source
5
Enable the trigger system
6
Fetch the triggered measurements
SCPI Triggering Nomenclature
The dc source uses the following sequence name and alias for the measurement trigger system. The alias
can be used instead of the sequence form.

Measurement Trigger Model
Figure 7-4 is a model of the measurement trigger system. The rectangular boxes represent states. The
arrows show the transitions between states. These are labeled with the input or event that causes the
transition to occur.
