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.
MEASure:ARRay:CURRent?
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.
