Spectrum Master Programming Manual : GSM Commands : :MEASure Subsystem
 
:MEASure Subsystem
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. Refer to 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:DEMod?
Title
Measure Demodulator
Description
Sets the active measurement to Demodulator, sets the default measurement parameters, triggers a new measurement and returns the Phase Error (rms), Phase Error (peak), EVM (rms), EVM (peak), Origin Offset, C/I, Magnitude Error (rms), Modulation Type, and TSC measurement. It is a combination of the commands :CONFigure:DEMod and :READ:DEMod? To make a Demodulator measurement with settings other than the default values, send:
CONFigure:DEMod
Commands to set desired settings
READ:DEMod?
Data is returned as 9 comma‑delimited values: Phase Error (rms), Phase Error (peak), EVM (rms) in %, EVM (peak) in %, Origin Offset in dB, C/I in dB, Magnitude Error (rms) in %, Modulation Type, and TSC.
“‑‑” is returned for each data that is not valid at that instance.

Title
Measure PASS/FAIL
Description
Sets the active measurement to PASS/FAIL, sets the default measurement parameters, triggers a new measurement and returns the PASS/FAIL results. It is a combination of the commands :CONFigure:PFail and :READ:PFail? To configure the PASS/FAIL measurement with settings other than the default values, send:

:MEASure:PVTFrame?
Title
Measure Power vs. Time (Frame)
Description
Sets the active measurement to Power vs. Time (Frame), sets the default measurement parameters, triggers a new measurement and returns the Channel Power, Burst Power, Average Burst Power, Span, Occupied Bandwidth, Frequency Error, Frequency Error (ppm), Modulation Type, and TSC measurement. It is a combination of the commands :CONFigure:PVTFrame and :READ:PVTFrame? To make a Power vs. Time (Frame) measurement with settings other than the default values, send:
:CONFigure:PVTFrame
Commands to set desired settings
READ:PVTFrame?
Data is returned as 9 comma‑delimited values: Channel Power in dBm, Burst Power in dBm, Average Burst Power in dBm, Span in MHz, Occupied Bandwidth in MHz, Frequency Error in MHz, Frequency Error (ppm), Modulation Type, and TSC. “‑‑” is returned for each data that is not valid at that instance.

Title
Measure Power vs. Time (Slot)
Description
Sets the active measurement to Power vs. Time (Slot), sets the default measurement parameters, triggers a new measurement and returns the Channel Power, Burst Power, Average Burst Power, Span, Occupied Bandwidth, Frequency Error, Frequency Error (ppm), Modulation Type, and TSC measurement. It is a combination of the commands :CONFigure:PVTSlot and :READ:PVTSlot? To make a Power vs. Time (Slot) measurement with settings other than the default values, send:
CONFigure:PVTSlot
Commands to set desired settings
