Carrier-to-noise measurements are not available in zero span mode.
Note: Carrier-to-noise measurements are also available in the I/Q Analyzer, but only
for Spectrum displays (see "Display Config" on page 460).
For general information on performing carrier-to-noise ratio measurements see Chap-
ter 6.1.1.3, "Measuring the Carrier-to-Noise Ratio" , on page 249.
C/N ← C/N, C/No ← I/Q Analyzer
Switches the measurement of the carrier/noise ratio on or off. If no marker is active,
marker 1 is activated.
The measurement is performed on the trace that marker 1 is assigned to. To shift
marker 1 and measure another trace, use the
Marker to Trace softkey in the "Marker
To" menu.
Remote command:

C/No ← C/N, C/No ← I/Q Analyzer
Switches the measurement of the carrier/noise ratio with reference to a 1 Hz bandwidth
on or off. If no marker is active, marker 1 is activated.
The measurement is performed on the trace that marker 1 is assigned to. To shift
marker 1 and measure another trace, use the
Marker to Trace softkey in the "Marker
To" menu.

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 730
Adjust Settings ← C/N, C/No ← I/Q Analyzer
Enables the RMS detector (see also Chapter 6.3.1.5, "Detector Overview" ,
on page 399) and adjusts the span to the selected channel bandwidth according to:
"4 x channel ban 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.
