How to Determine the Carrier-to-Noise Ratio

The following step-by-step instructions demonstrate how to determine the carrier-to-
noise ratio.

For remote operation, see

"Programming example: Measuring the carrier-to-noise

1. Press the "C/N", "C/N0" softkey to configure the carrier-to-noise ratio measure-

ment.

2. To change the channel bandwidth to be analyzed, press the "Channel Bandwidth"

softkey.

3. To optimize the settings for the selected channel configuration, press the "Adjust

Settings" softkey.

4. To activate the measurements without reference to the bandwidth, press the "C/N"

softkey.
To activate the measurements with reference to the bandwidth, press the "C/N

0

"

softkey .

5. If the carrier signal is located within the analyzed channel bandwidth, switch off the

carrier signal so that only the noise is displayed in the channel and perform a sec-
ond measurement.

The carrier-to-noise ratio is displayed after the measurement has been completed.

Occupied Bandwidth Measurement (OBW)

An important characteristic of a modulated signal is its occupied bandwidth, that is: the
bandwidth which must contain a defined percentage of the power. In a radio communi-
cations system, for instance, the occupied bandwidth must be limited to enable distor-
tion-free transmission in adjacent channels.

About the Measurement

The occupied bandwidth is defined as the bandwidth containing a defined percentage
of the total transmitted power. A percentage between 10 % and 99.9 % can be set.
