USER'S MANUAL. PROLINK-3/3C
For the power measurement of a digital channel to be correct it is essential to
have previously defined the channel bandwidth using the Channel BW function, in the
TV mode functions menu (see section '4.9.4.11 Channel Bandwidth').

Before measuring the BER or analysing the Wrong Packets in the Transport
Stream MPEG-2 / DVB is necessary to define some parameters concerning the digital
signal, which are described in the following section (see section '4.9.1.5.1. Measuring
BER of QAM Digital Channels (QAM)'). To see its present value or to modify it, being in
the BER measuring screen, press the rotary selector, it will appear a multiple-choice
menu showing the functions relative to the BER measurement on the screen.
Once set-up the necessary parameters for tuning and measuring the digital
