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.
Remote command:
CALC:MARK:FUNC:POW:SEL CN
CALC:MARK:FUNC:POW:RES? CN
CALC:MARK:FUNC:POW:SEL CN0
CALC:MARK:FUNC:POW:RES? CN0
CALC:MARK:FUNC:POW OFF
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.
