:MEASure:DEMod:CONStln?
Title:
Measure Constellation
Description:
Triggers a new Constellation measurement and returns the results. The
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.

:MEASure:OTA:C4AGGregation?
Title:
Measure OTA Carrier Aggregation (4x4 MIMO configuration)
Description:
Sets the active measurement to Carrier Aggregation, 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:OTA:CAGGregation? command, instead. Refer to your
instrument User Guide for instructions on updating firmware.
Data is returned as 70 comma delimited values. The values consist of
5 sets of Component Carrier (CC) data, with each set containing
14 fields (CP, tx1 antenna, tx2 antenna, tx3 antenna, tx4 antenna,
RS Power, RS Delta Power, SS Power, EVM(rms), EVM(pk),
Freq Error, Freq Error (ppm), TAE (nS), and Cell ID). The data is in
sequential CC order. A field with “--” means the data was invalid. An
inactive Component Carrier will show N/A for the entire set of data.

:MEASure:OTA:CAGGregation?
Title:
Measure OTA Carrier Aggregation
Description:
Sets the active measurement to Carrier Aggregation, triggers a new
measurement, and returns the measured values.
Data is returned as 60 comma delimited values. The values consist of
5 sets of Component Carrier (CC) data with each set containing
12 fields (CP, tx1 antenna, tx2 antenna, RS Power, RS Delta Power,
SS Power, EVM(rms), EVM(PK), Freq Error, Freq Error (ppm),
TAE (nS), and Cell ID). The data is in sequential CC order. A field with
“--” means the data was invalid. An inactive Component Carrier will
show N/A for the entire set of data.
