Important Remark; Selecting The Measurements - Promax TV EXPLORER HD+ Manual De Instrucciones

NOTE: In the channel tuning mode the Polarization and Sat Band options cannot be
modified.
This configuration menu shows, besides the QPSK/8PSK signal parameters
selected by user, all the values automatically detected:
Roll Off Nyquist filter roll-off factor.
Pilots (Only in DVB-S2) Pilots detection in transmission.
DVB channels tuning may require an adjusting process. It is recommended to follow
next procedure:
1. From the spectrum analyser mode
frequency.
2. Switch to Measurements mode
3. If in the lower line of the screen does not appear MPEG-2 message (and
consequently BER is unacceptable), by turning the rotary selector deviate the
tuning frequency until MPEG-2 message appears. Finally tune channel again
to minimize the frequency deviation which optimises the BER and therefore
minimize the BER.
If it is not possible to detect any MPEG-2 channel, make sure that digital signal
parameters are correctly defined.
