12 MEASure Subsystem158 Keysight U2040 X-Series Programming GuideMEASure[1]|2|3|4[:SCALar][:POWer][:AC]?SyntaxMEASure[1]|2|3|4[:SCALar][:POWer][:AC]?[[,[,]]]DescriptionThis command sets the specified CALCulate block measurement function to singlechannel with relative mode off, aborts, configures the CALCulate block then initiatesChannel A, calculates the measurement result, and places the result on the bus.The values shown in this command are those that are tested.ParametersExampleItem 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.A numeric value for the expected power level. The units ofmeasurement are dBm and W. The default units are defined byUNIT:POWer.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)The channel which the command is implemented on. Ifunspecified, the current setup is used. If the ratio or differencemeasurement was set up, it will default to Channel A.MEAS2? -20DBM,1,(@1)Queries the CALCulate2 measurement of Channel A,using an expected power level of –20 dBm and aresolution setting of 1.
