FETCh Subsystem
Fetch commands return measurement data that has been previously acquired. FETCh queries do not
generate new measurements, but allow additional measurement calculations from the same acquired
data.The data is valid until the next MEASure or INITiate command occurs.
FETCh[:SCALar]:CURRent[:DC]? [<start_index>, <points>]
FETCh[:SCALar]:VOLTage[:DC]? [<start_index>, <points>]
FETCh[:SCALar]:POWer[:DC]? [<start_index>, <points>]
Returns the averaged measurement. Values returned are either in amperes, volts, or watts.

Parameter Typical Return
[<startindex>] the start index
[<points>] the number of points
<DC value>
Returns the measured DC current FETC:CURR?
FETCh[:SCALar]:CURRent:ACDC?
FETCh[:SCALar]:VOLTage:ACDC?
Returns the RMS measurement (AC + DC). Values returned are either in amperes, or volts.

(none) <ACDC value>
Returns the measured RMS voltage FETC:VOLT:ACDC?
FETCh[:SCALar]:CURRent:HIGH?
FETCh[:SCALar]:VOLTage:HIGH?
Returns the High level of a pulse waveform. Values returned are either in amperes, or volts. See
Measurement Types.
Parameter Typical Return
(none) <HIGH value>
Returns the measured high level current FETC:CURR:HIGH?
