Antenna Adjustment For Optimum Signal Quality (3> Adjust) - Promax PRODIG-1+ Manual De Instrucciones

USER'S MANUAL PRODIG-1+.
Signal Quality
The IDENTIFY function also shows the information regarding the signal quality.
Now, when a signal with a valid transport stream is detected, the PRODIG-1+ shows
'lock' on the display and proceeds to measure the BER.
(approximately 5 s later) the 'lock' indication changes to 'BER' if the BER is < 2x10E-4
(equivalent to good quality) or 'ber' if the BER is > 2x10E-4 (equivalent to poor quality).
BER measurement will be repeated every 5 s.
The QPSK demodulator circuit tends to measure better as time passes due to the fact
that it includes an input signal tracking and adaptation algorithm. Therefore, to ensure a
correct signal quality reading, you are recommended to wait until a few measurements
have been taken.
4.2.3 Antenna Adjustment for Optimum Signal Quality (3> ADJUST)
Once the antenna has been positioned so that it receives maximum power and
checked that it is pointing to the right satellite, you should adjust the antenna so that it
produces optimum reception quality. Press button
function. This function measures the signal noise ratio SNR at the digital demodulator
output and shows the measured value on the screen both numerically (in dB) and
graphically.
