Measurement process

Depending on whether the carrier is inside or outside the analyzed channel, the mea-
surement process for the carrier-to-noise ratio varies:

●

The carrier is outside the analyzed channel: In this case, it is sufficient to switch on
the desired measurement function and to set the channel bandwidth. The carrier/
noise ratio is displayed on the screen.

●

The carrier is inside the analyzed channel: In this case, the measurement must be
performed in two steps:
–

First, perform the reference measurement by switching on either the C/N or the
C/N

0

measurement and waiting for the end of the next measurement run. The

fixed reference marker is set to the maximum of the measured carrier signal.

–

Then, switch off the carrier so that only the noise of the test setup is active in
the channel. The carrier-to-noise ratio is displayed after the subsequent mea-
surement has been completed.

Frequency Span

The frequency span should be set to approximately twice the channel bandwidth in
order to measure the carrier-to-noise ratio correctly. This setting is defined automati-
cally by the "Adjust Settings" function.

7.4.2

Carrier-to-Noise Results

As a result of the carrier-to-noise measurement the evaluated bandwidth and the cal-
culated C/N ratio are displayed in the result window. The fixed reference marker is indi-
cated in the diagram.
