You can also query the determined carrier-to-noise ratio via the remote command
CALC:MARK:FUNC:POW:RES? CN
or
CALC:MARK:FUNC:POW:RES? CN0
, see
CALCulate<n>:MARKer<m>:FUNCtion:POWer:RESult?
on page 721.

C/N, C/No
Opens a submenu to configure the carrier/noise ratio measurement. Measurements
without (C/N) and measurements with reference to the bandwidth (C/No) are possible.
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
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.

C/No ← C/N, C/No
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
Opens an edit dialog box to enter the measurement channel bandwidth for each chan-
nel.
The default setting is 14 kHz.
