One-Button Measurement Functions
Remote Command Notes: The main channel power is returned in the current amplitude
units, and the lower and upper channel results are always returned in dB.
Example: FETC:ACP? or MEAS:ACP? or READ:ACP? commands return the scalar
results of main channel power, lower channel power (relative), and upper
channel power (relative) if only one offset is set to on and the Radio
Standard is set to None. Otherwise, 28 values are returned. If
Meas Typeis
Total Power Ref, these are the main channel power in dBm and in dBc from
the carrier (0 dBc) each repeated, followed by the absolute and relative
power levels for each lower and upper offset if Meas Type is Total Power
Ref. Otherwise they are the main channel power spectral density and
relative power spectral density
(0 dB) each repeated, followed by the absolute and relative spectral density
values for each lower and upper offset.

25. Negative Offset Frequency (6)
- relative power (dB)
26. Negative Offset Frequency (6)
- absolute power (dBm)
27. Positive Offset Frequency (6)
- relative power (dB)
28. Positive Offset Frequency (6)
- absolute power (dBm)
Main channel relative power is relative to
the main channel power spectral density,
and therefore is always equal to 0.00 dB.
