These commands take the instrument from its current state, enable the specified measurement and put the instrument into single sweep mode. They correct any parameters that are invalid given the new measurement state such that a valid measurement can take place. Other settings may be changed; see the documentation of CONFigure for each measurement. They then initiate the measurement. When the measurement is complete, they return the result.
To make a measurement with settings other than the “default” measurement settings applied by CONFigure, do the following:
• Send the appropriate CONFigure command to set the desired measurement.
• Modify the settings as required.
• Send the appropriate READ command to measure and return the result.
To get the current measurement data, use the appropriate FETCh command.
:MEASure:ACPower?
Title
Measure Adjacent Channel Power Ratio
Description
Sets the active measurement to adjacent channel power ratio, sets the default measurement parameters, triggers a new measurement and returns the main channel power lower adjacent and upper adjacent channel power results. It is a combination of the commands :CONFigure:ACPower; :READ:ACPower? For a description of the default adjacent channel power ratio measurement parameters see :CONFigure:ACPower. To make an adjacent channel power ratio measurement with settings other than the default values send:
:CONFigure:ACPower Commands to set desired settings :READ:ACPower?
Data is returned as 3 comma-separated values: main channel power, lower adjacent channel power, upper adjacent channel power.
Default Unit
Current amplitude units

Title
Measure Channel Power
Description
Sets the active measurement to channel power, sets the default measurement parameters, triggers a new measurement and returns the channel power result. To measure both channel power and channel power density use :MEASure:CHPower? It is a combination of the commands :CONFigure:CHPower; :READ:CHPower:CHPower? For a description of the default channel power measurement parameters see :CONFigure:CHPower. To make a channel power measurement with settings other than the default values send:
:CONFigure:CHPower Commands to set desired settings :READ:CHPower:CHPower?
Sets the active measurement to channel power, sets the default measurement parameters, triggers a new measurement and returns the channel power density result. To measure both channel power and channel power density use :MEASure:CHPower? It is a combination of the commands :CONFigure:CHPower; :READ:CHPower:DENSity? For a description of the default channel power measurement parameters see :CONFigure:CHPower. To make a channel power measurement with settings other than the default values send:
:CONFigure:CHPower Commands to set desired settings :READ:CHPower:DENSity?
Sets the active measurement to channel power, sets the default measurement parameters, triggers a new measurement and returns the channel power and channel power density results. It is a combination of the commands :CONFigure:CHPower; :READ:CHPower? For a description of the default channel power measurement parameters see :CONFigure:CHPower. To make a channel power measurement with settings other than the default values send:
:CONFigure:CHPower Commands to set desired settings :READ:CHPower?
Data is returned as 2 comma-separated values: channel power, channel power density.
Initiates an IQ capture sequence. If SINGle is passed as an argument, the data will be saved to a file on the instrument. SINGle is also the default if no parameter is passed. If REMote is passed as an argument, then data will be routed to the SCPI output and must be received using MEASure:IQ:GET?. See IQ Waveform Capture for an IQ_SCPI.cpp example of how to use these two commands together to quickly transfer the captured data to a PC.
Parameter

:MEASure:OBWidth?
Title
Measure Occupied Bandwidth
Description
Sets the active measurement to occupied bandwidth, sets the default measurement parameters, triggers a new measurement and returns the occupied bandwidth, percent of power and dB down results. It is a combination of the commands :CONFigure:OBWidth; :READ:OBWidth? For a description of the default occupied bandwidth measurement parameters see :CONFigure:OBWidth. To make an occupied bandwidth measurement with settings other than the default values send:
:CONFigure:OBWidth Commands to set desired settings :READ:OBWidth?
Data is returned as 3 comma-separated values: occupied bandwidth, percent of power, dB down.
Default Unit
For OBW: Hz For Percent of Power: % For dB Down: dB
