12-7 :MEASure Subsystem Chapter 12 — Mobile WiMAX Commands
12-12 PN: 10580-00341 Rev. C MS2720T PM
12-7 :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:CONStln?
Title: Measure Constellation
Description: Sets the active measurement to Constellation, sets the default
measurement parameters, triggers a new measurement, and returns
the EVM (rms), EVM (pk), RCE (rms), RCE (pk), Carrier Frequency,
Freq Error, Freq Error, and the Base Station ID. It is a combination of
the commands :CONFigure:DEMod CONStln and
:READ:DEMod:CONStln? To make a Demodulated Constellation
measurement with settings other than the default values send:
:CONFigure:DEMod CONStln
Commands to set desired settings
:READ:DEMod:CONStln?
Data is returned as 8 comma-delimited values: EVM (rms) in %, EVM
(pk) in %, RCE (rms) in dB, RCE (pk) in dB, Freq Error in MHz, CINR
in dB, Base Station ID, and the Sector ID.
