: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

: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 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.

:FETCh:RF:ACLR?

Title

Fetch Adjacent Channel Leakage Ratio

Description

Returns the most recent adjacent channel leakage ratio measurement results. If the instrument is sweeping, it will not return until the sweep is complete. Refer to “:READ:RF:ACLR?” for a description of the returned data.

Default Unit

dBm

:FETCh:RF:SEM?

Title

Fetch Spectral Emission Mask

Description

Returns Spectral Emission Mask measurement results (Pass or Fail).

Front Panel Access

Measurements, RF, Spectral Emission Mask

Returns the most recent RF Spectrum measurement results. Data is returned as
2 comma-delimited values: Channel Powerin dBm and Occupied bandwidth measurement in MHz. “--” is returned for each data that is not valid at that instance.

Front Panel Access

Measurements, RF, Channel Spectrum

Returns the values displayed in a Summary measurement view. If the current display is not a summary screen, then the return value is ‘N/A’. The return value is a comma separated list of the values displayed on the screen, in the order they are displayed from top to bottom. The list is preceded by the name of the summary view; either “TD-LTE Summary”, “RF Summary” or “Modulation Summary”.
