The displayed sample rate is identical to the sample rate defined under Data Acquisi-
tion (I/Q Analyzer) and is not editable here.
For details see "Digital Output" in the description of the R&S Digital I/Q Interface for the
base unit.
Remote command:
OUTPut:DIQ on page 772
Digital IQ Info ← I/Q Analyzer
Displays a dialog box with information on the digital I/Q input and output connection via
the optional R&S Digital I/Q Interface (R&S FSV-B17), if available. The information
includes:
●
Device identification
●
Used port
●
(Maximum) digital input/output sample rates and maximum digital input/output
transfer rates
●
Status of the connection protocol
●
Status of the PRBS descewing test
For details see "Interface Status Information" in "Instrument Functions - R&S Digital I/Q
Interface (Option R&S FSV-B17)" in the description of the base unit.
Remote command:
INPut:DIQ:CDEVice on page 760
C/N, C/No ← I/Q Analyzer
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: As of firmware version 2.0, carrier-to-noise measurements are also available in
the I/Q Analyzer, but only for Spectrum displays (see "Display Config" on page 447).
For general information on performing carrier-to-noise ratio measurements see Chap-
ter 3.3.5.3, "Measuring the Carrier-to-Noise Ratio", on page 337.
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.

CALCulate<n>:MARKer<m>:FUNCtion:POWer[:STATe] on page 704
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.
