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
For general information on performing carrier-to-noise ratio measurements see
ter 6.1.1.3, "Measuring the Carrier-to-Noise
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
To" menu.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:POWer:SELect
CALCulate<n>:MARKer<m>:FUNCtion:POWer:RESult?
CALCulate<n>:MARKer<m>:FUNCtion:POWer[:STATe]
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
To" menu.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:POWer:SELect
CALCulate<n>:MARKer<m>:FUNCtion:POWer:RESult?
CALCulate<n>:MARKer<m>:FUNCtion:POWer[:STATe]
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
Adjust Settings ← C/N, C/No ← I/Q Analyzer
Enables the RMS detector (see also
on page 399) 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.
