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]:POWer[:DC]?
FETCh[:SCALar]:VOLTage[:DC]? [<start_index>, <points>]
Returns the averaged measurement. Values returned are either in amperes, volts, or watts.
Optional parameters specify a subset starting at <startindex> and of length <points>.
Parameter
[<startindex>] the start index
[<points>] the number of points
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.
Parameter
(none)
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
(none)
Returns the measured high level current FETC:CURR:HIGH?
