Chapter6 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
specified number of samples, storing the results in a buffer, and calculating the
measured result. Two types of measurement commands are available:
MEASure and FETCh. MEASure commands trigger the acquisition of new data
before returning the reading. FETCh commands return a reading computed
from previously acquired 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.
MEASure:ARRay:CURRent?
FETCh:ARRay:CURRent?
These queries return an array containing the instantaneous output current in
amps. The output voltage or current is digitized whenever a measure command
is sent or 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.
