Measurement Commands

Measurement commands consist of measure and sense commands.
Measure commands measure the output voltage or current. Measurements are performed by digitizing
the instantaneous output voltage or current for a defined number of samples and sample interval, storing
the results in a buffer, and calculating the measured result. Two types of measurement commands are
available: MEASure and FETCh. MEASure triggers the acquisition of new data before returning the
reading; FETCh returns a reading computed from previously acquired data. If you take a voltage
measurement, you can fetch only voltage data.
Use MEASure when the measurement does not need to be synchronized with any other event.
Use FETCh when it is important that the measurement be synchronized with either a trigger or
with a particular part of the output waveform.
Sense commands control the current measurement range, the bandwidth detector of the , and the data
acquisition sequence.

FETCh:ARRay:CURRent?
Agilent 66312A, 66332A Only
These queries return an array containing the instantaneous output current in amperes. The output voltage
or output current are digitized whenever a measure command is given or whenever an acquire trigger
occurs. The time interval is set by SENSe:SWEep:TINTerval. The position of the trigger relative to the
beginning of the data buffer is determined by SENSe:SWEep:OFFSet. The number of points returned is
set by SENSe:SWEep:POINts.
