Channel Bandwidth (Channel BW)
To measure the power and C/N ratio of digital channels, as well as the C/N ratio
of satellite band channels, you first need to define the channel bandwidth.
02/2003
The PROLINK-4 defines automatically the frequency
where noise level is measured, according with:
f noise = f tuning - ½ Channel BW.
The user defines the frequency where noise level is
measured (by means of the Reference noise
function). This frequency will be used to measure
noise level for all channels.
