:READ:RF:ACLR?
Title:
Read Adjacent Channel Leakage Ratio
Description:
Triggers a new Adjacent Channel Leakage Ratio measurement and
returns the results: Power levels for each channel (both absolute and
relative). If the instrument is sweeping, it will not return until the
sweep is complete. If the instrument is not sweeping and the current
data is not valid it will return error –230. This could occur if there was a
*RST immediately before the :FETCh? or if a measurement parameter
was changed without an :INITiate.
Data is returned as 11 comma-separated values: Main channel power,
Left alternate channel power - relative, absolute , Left adjacent channel
power - relative, absolute,
Main channel power - relative,absolute, Right adjacent channel
power - relative, absolute, Right Alternate channel power - relative,
absolute.
Default Unit:

:READ:RF:SEM?
Title:
Read RF Spectral Emmision Mask
Description:
Triggers a new RF Spectral Emission Mask measurement and returns a
PASS or FAIL result. It is a combination of the commands :ABORT;
:INITiate; :FETCh:RF:SEM?
The current measurement can be queried using :CONFigure?

:READ:RF:SPECtrum?
Title:
Read RF Spectrum
Description:
Triggers a new RF Spectrum measurement and returns the results:
Channel Power and Occupied BW measurement. It is a combination of
the commands :ABORT; :INITiate; :FETCh:RF:SPECtrum? The current
measurement can be queried using :CONFigure?
Data is returned as 2 comma-delimited values: Channel Power in dBm
and Occupied bandwidth measurement in MHz.
