Returning All Measurement Data From the Data Buffer
The MEASure:ARRay and FETCh:ARRay queries return all data values of the instantaneous voltage or
current buffer. No weighting function is applied when returning the raw data from the array. The
commands are:
MEASure:ARRay:CURRent?
MEASure:ARRay:VOLTage?

Internally Triggered Measurements

You can use the data acquisition trigger system to synchronize the timing of the voltage and current data
acquisition with a BUS or internal trigger source. Then use the FETCh commands to return different
calculations from the data acquired by the measurement trigger.

SCPI Triggering Nomenclature

As previously explained under "Triggering Output Changes", the dc source uses the following sequence
name and alias for the measurement trigger system. This alias can be used instead of the sequence form.
Sequence Form
SEQuence2

Measurement Trigger System 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.
