It sets the measurement function to difference with relative mode on.The relative value used is set by the CALCulate:RELative:MAGNitude:AUTOcommand.The values shown in this command are those that are tested.This query returns the present configuration of the specified CALCulate block.ParametersItem Range of values Description/Default valueexpected_value(for the expected powerlevel)sensor-dependentDEF[a][a] The mnemonic DEF means DEFault. This is not equivalent to the DEFault parameter used in the commandsubsystems. The parameters must be entered in the specified order. If parameters are omitted, they default from theright. The parameter DEFault is used as a placeholder. Specifying DEF leaves the parameter value unchanged.The U2040 X-Series ignores the numeric value entered in thisparameter. Any value entered is treated like DEF.resolution1 to 4[b]1.0, 0.1, 0.01, 0.001DEF[a][b] When SENS:AVER:COUN:AUTO is enabled, the resolution setting affects the number of averages applied. Refer to“Auto-averaging mode” on page 44 for more information.A numeric value for the resolution. If unspecified, the currentresolution setting is used.source_list (@1),(@1)This channel list specifies the channels used to calculate thedifference.If unspecified and the current setup is a differencemeasurement, then this difference setup is used, otherwise itdefaults to Channel A-A.
