3.3.4.3.2.2.- Automatic C/N

The automatic C/N measurement for digital channels is the same as for analogue channels. This
function has the following submenu:

3.3.4.3.2.2.1.- Channel bandwidth

When this parameter is selected, the information about the channel power measurement
disappears and the channel bandwidth appears in its place. This can be modified using the
rotating knob. To select the desired value, press the rotating knob. The bandwidth information
will disappear and the power measurement information will appear again.

3.3.4.3.2.3.- Referenced C/N 

The measurement of the C/N of digital channels is also displayed on the lower left-hand part of
the screen. The user must select the frequency value that will be used to carry out the noise
measurement and the channel bandwidth. This function has the following submenu:

3.3.4.3.2.3.1.- Reference frequency

This function lets you vary the frequency that will be used to measure the noise. Use the rotating
knob to move the blue marker through the range of frequencies that are visible onscreen. Once
the marker is signalling the desired frequency, press the rotating knob. The C/N measurement
will be carried out using this frequency as the noise reference.

3.3.4.3.2.3.2.- Channel bandwidth

When this parameter is selected, the information about the channel power measurement
disappears and the channel bandwidth appears in its place. This can be modified using the
rotating knob. To select the desired value, press the rotating knob. The bandwidth information
will disappear and the power measurement information will appear again.
