Channel Bandwidth ← C/N, C/No ← I/Q Analyzer
Opens an edit dialog box to enter the measurement channel bandwidth for each chan-
nel.
The default setting is 14 kHz.
Note that in the I/Q Analyzer the channel bandwidth does not change the measure-
ment span or sampling rate; it merely defines the range for the carrier-to-noise analy-
sis.
Remote command:
[SENSe:]POWer:ACHannel:ACPairs on page 842
Adjust Settings ← C/N, C/No ← I/Q Analyzer
Enables the RMS detector (see also Chapter 3.2.8.6, "Detector Overview",
on page 265) and adjusts the span to the selected channel bandwidth according to:
"4 x channel bandwidth + measurement margin"
The adjustment is performed once; if necessary, the setting can be changed later on.
Note: in the I/Q Analyzer, this function is not available. The channel bandwidth defines
the range for the carrier-to-noise analysis.
