MEASure Commands

These command 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 Adjacent Channel Power Ratio

:MEASure:ACPower?

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 Units:	Current amplitude units
See Also:	:CONFigure:ACPower

 

Measure Channel Power/Density

:MEASure:CHPower?

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.

Default Units:	Current amplitude units
See Also:	:MEASure:CHPower:CHPower? :MEASure:CHPower:DENSity? :CONFigure:CHPower

 

Measure Channel Power

:MEASure:CHPower:CHPower?

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?

Default Units:	Current amplitude units
See Also:	:MEASure:CHPower? :MEASure:CHPower:DENSity? :CONFigure:CHPower

 

Measure Channel Power Density

:MEASure:CHPower:DENSity?

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?

Default Units:	Current amplitude units
See Also:	:MEASure:CHPower? :MEASure:CHPower:CHPower? :CONFigure:CHPower

 

Measure Occupied Bandwidth

:MEASure:OBWidth?

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 Units:	For OBW: Hz For Percent of Power: % For dB Down: dB
See Also:	:CONFigure:OBWidth

 

Measure Tracking Generator Absolute Statistics

:MEASure:TGENerator:ABSStats?

Sets the active measurement to tracking generator with absolute statistics on, sets the default measurement parameters, triggers a new measurement and returns the results.

It is a combination of the commands :CONFigure:TGENerator ABSStats;:READ:TGENerator:ABSStats?

For a description of the default tracking generator absolute statistics measurement parameters see :CONFigure:TGENerator ABSStats.

To make an tracking generator absolute statistics measurement with settings other than the default values send

•	:CONFigure:TGENerator ABSStats

•	Commands to set desired settings

•	:READ:TGENerator:ABSStats?

Data is returned as 3 comma-separated values: absolute max power, absolute min power, absolute average power.

Default Units:	Current amplitude units
