7-7 :MEASure Subsystem

7-7 :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; 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:DEMod:CONStln?
Title: Measure Constellation
Description: Sets the active measurement to Constellation, sets the default
Related Command: :READ:DEMod:CONStln?
:MEASure:DEMod:EVSCarrier?
Title: Measure EVM vs. Sub Carrier
Description: Sets the active measurement to EVM vs. Sub Carrier, sets the default
7-12
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, Carrier Frequency in MHz, Freq
Error in MHz, Freq Error in ppm, and the Base Station ID.

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 EVSCarrier and
:READ:DEMod:EVSCarrier? To make an EVM vs. Symbol
measurement with settings other than the default values, send:
