2. The carrier is inside the channel examined:

In this case, the measurement must be performed in two steps. First, the 
reference measurement is performed with the carrier being active. This is done by 
switching on either the C/N or the C/No measurement and waiting for the end of 
the next measurement run. Then, the carrier is switched off so that only the noise 
of the test setup is active in the channel. The carrier/noise ratio is displayed after 
the subsequent measurement has been completed.

The 

ADJUST SETTINGS

 function facilitates the selection of the frequency span

appropriate for the channel bandwidth: it automatically sets the 

SPAN

 to approx. 4 ×

channel bandwidth.

The RMS detector is enabled when the power measurement is switched on
(

TRACE-DETECTOR-RMS)

.

C/N /
C/NO

The 

C/N C/NO

 softkey opens the submenu for configuring the carrier/noise ratio

measurement. 

The user can choose between measurement without (C/N) and measurement with
reference to the bandwidth (C/No). In addition, it is possible to select the bandwidth
of the channel and to adapt the span.

C/N /

C/NO

The 

C/N 

and

 C/NO 

softkeys enable and disable the measurement of the carrier/

noise ratio, the C/No measurement also being referred to a 1 Hz bandwidth. 

The maximum value of the current trace is determined when the function is activated
and is marked by means of the 

REFERENCE FIXED 

marker.

The measurements are only available in the frequency domain (span >0).

The measurement is performed on the trace where MARKER 1 is located. To mea-
sure another trace, MARKER 1 has to be shifted to the trace in question using the

SELECT TRACE

 softkey in the 

MARKER

 menu.

If no marker is active, MARKER 1 is activated when the function is switched on.
