Mobile WiMAX Commands 8-4 :FETCh Subsystem
S412E PM PN: 10580-00319 Rev. N 8-7
8-4 :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:CONStln?
Title: Fetch Constellation
Description: Returns the constellation of the demodulated data symbol over one
frame measurement results.
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. “--” is
returned for each data that is not valid at that instance.
:FETCh:DEMod:EVSCarrier?
Title: Fetch EVM vs. Sub Carrier
Description: Returns the EVM vs. Sub Carrier measurement results.
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. “--” is
returned for each data that is not valid at that instance.
:FETCh:DEMod:EVSYmbol?
Title: Fetch EVM vs. Symbol
Description: Returns the EVM vs. Symbol measurement results.
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. “--” is
returned for each data that is not valid at that instance.
:FETCh:DEMod:SFLatness?
Title: Fetch Spectral Flatness
Description: Returns the absolute delta of the power between adjacent sub carriers
in dB. “--” is returned for data that is not valid at that instance.
