14-5 :FETCh Subsystem Chapter 14 — TD-LTE Commands
14-10 PN: 10580-00341 Rev. C MS2720T PM
14-5 :FETCh Subsystem
This set of commands returns the most recent measurement data of the active measurement.
They will not switch to another measurement.
To make a new measurement, use the INITiate command. To get new measurement data, use
the READ or MEASure query commands.
:FETCh:DEMod:CCPData?
Title: Fetch Demodulator Code Domain Power Data
Description: Returns the most recent Control Channel Power measurement numeric
results.
Data is returned as 24 comma-delimited 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
Front Panel
Access: Measurements, Modulation, Control Channel Power
:FETCh:DEMod:CONStln?
Title: Fetch Constellation
Description: Returns the constellation measurement numeric results of the
demodulated data symbol over one sub-frame measurement. Data is
returned as 9 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, the Cell ID, and the number of measurements
used in the frequency error average. “--” is returned for each data that is
not valid at that instance.

Access: Measurements, Modulation, Constellation
:FETCh:OTA:SCANner?
Title: Fetch OTA Scanner
Description: Returns the most recent OTA Scanner measurement results.
Data is returned as 6 sets of comma-delimited values. Each set as
follows: Cell ID, Group ID, Sector ID, S-SS Power, RSRP, RSRQ, and
SINR
Following the six sets of data is a final value for the Dominance.
“--” is returned for each data that is not valid at that instance.
