S331E, S332E, S361E, S362E Site Master™MS2711E, MS2712E, MS2713E Spectrum Master™MT8212E, MT8213E Cell Master™ Programming Manual : CDMA 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; 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:CDPower?
Title
Measure Code Domain Power
Required Option

Description
Sets the active measurement to Code Domain Power, sets the default measurement parameters, triggers a new measurement and returns the Pilot Power, Channel Power, Noise Floor, Rho, Carrier Feed Through, Tau, RMS Phase Error, Frequency Error, Frequency Error PPM, Page, Sync, and Q Page measurement results. It is a combination of the commands :CONFigure:DEMod CDPower and :READ:DEMod:CDPower? To make a CDP measurement with settings other than the default values, send:
:CONFigure:DEMod CDPower
Commands to set desired settings
:READ:DEMod:CDPower?
Data is returned as 12 comma-delimited values: Pilot Power in the current user set unit (dBm/W/mW), Channel Power in the current user set unit (dBm/W/mW), Noise Floor in dB, Rho, Carrier Feed Through in dB, Tau in ps, RMS Phase Error in deg, Frequency Error in Hz, Frequency Error PPM, Page in dBm, Sync in dBm, and Q Page. All invalid values are replaced with “--”.

Title
Measure Adjacent Channel Power Ratio
Required Option
42
Description
Sets the active measurement to ACPR, sets the default measurement parameters, triggers a new measurement, and returns the power levels for each of the adjacent and main channels (9 total). It is a combination of the commands :CONFigure:RF ACPR and :READ:RF:ACPR? To make an RF ACPR measurement with settings other than the default values, send:
:CONFigure:RF ACPR
