Read Subsystem - Anritsu LMR Master S412E Programming Manual

LTE Commands
9-9

:READ Subsystem

This set of commands combines the ABORt, INITiate and FETCh commands. It aborts any
current triggering sequence and sets the trigger state to idle. It then initiates a new active
measurement (i.e. begins the collection of new data). When the measurement is complete, it
returns the result. These commands will not switch to another measurement.
To get the current measurement data, use the FETCh command.
:READ:DEMod:4x4:TIMEalign?
Title: Read Tx Time Alignment Data (4x4 MIMO configuration)
Description: Triggers a new Time Alignment measurement and returns the results.
Front Panel Access: Measurements, Modulation, Tx Time Alignment
:READ:DEMod:CONStln?
Title: Read Constellation
Description: Triggers a new Constellation measurement and returns the results. The
Front Panel Access: Measurements, Modulation, Constellation
S412E PM
The Tx Time Alignment measurement must be the active measurement
(specified by :CONFigure:DEMod TIMEalign). The current
measurement can be queried using the command :CONFigure?
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 :READ: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.
Constellation measurement must be the active measurement (specified
by :CONFigure:DEMod CONStln). The current measurement can be
queried using the command :CONFigure?
Data is returned as 8 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,
and the Cell ID. "--" is returned for each data that is not valid at that
instance.
