FAQ 145-2002-en

An "x" number of digital satellite channels have to be distributed in an IF installation.

Does the IF launch amplifier still have to be adjusted in terms of the number of satellite channels that have to be amplified?

Respuesta: 

The term "channels" in digital TV is no longer valid.

It is true that digital TV packages consist of many TV and radio channels, but this does not mean that a couple of carriers or a 36 MHz bandwidth spectrum are present in each channel.

The correct term is "transponders".

Therefore, the number of transponders is the data that must be used to calculate the reduction of the maximum output level in the amplifier.
