Measure Subsystem - Anritsu LMR Master S412E Programming Manual

9-8 :MEASure Subsystem

9-8 :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:4x4:TIMEalign?
Title: Measure Tx Time Alignment Data (4x4 MIMO configuration)
Description: Sets the active measurement to Tx Time Alignment, sets the default
Front Panel Access: Measurements, Modulation, Tx Time Alignment
:MEASure:DEMod:CCPData?
Title: Read Modulation Control Channel Power Data
Description: Sets the active measurement to Control Channel Power, sets the default
Front Panel Access: Measurements, Modulation, Control Channel Power

measurement parameters, triggers a new measurement, and returns
the measured values. This command may not be supported if your
instrument is loaded with older firmware, in which case you may
upgrade to the current firmware version or use the
:MEASure:DEMod:TIMEalign? command, instead. Refer to your
instrument User Guide for instructions on updating firmware.
Data is returned as 14 comma-delimited values: EVM (rms) in %,
EVM (pk) in %, Ref Signal (RS) Power in dBm, Sync Signal (SS) Power
in dBm, Carrier Frequency in MHz, Freq Error in Hz, Freq Error in
ppm, Cell ID, and Time Alignment Error (TAE) in nanoseconds for each
of antenna pairs 1-2, 1-3, 1-4, 2-3, 2-4, and 3-4. "--" is returned for each
data that is not valid at that instance.
measurement parameters, triggers a new measurement, and returns
the measured values: RS_POWER, PSS_POWER, SSS_POWER,
BCH_POWER, CFI_POWER, RS_TOTAL_POWER,
PSS_TOTAL_POWER, SSS_TOTAL_POWER, BCH_TOTAL_POWER,
CFI_TOTAL_POWER, TOTAL_POWER, TOTAL_CHANNEL_POWER.
Data returned is the same for Bar Graph or Table mode. The Control
Channel Power measurement must be the active measurement.
