6.2.3 Quality
This menu is used to test the signal quality and
the aerial reception quality. It may be necessary
to adjust or upgrade the TV aerial to ensure good
picture and sound on all channels. For more
information see Chapter 8.2.3.1 Reception.
The MyM-3T has an inbuilt spectrum analyser to
help optimise the aerial installation. For more
information see Chapter 8.2.3.2 Antenna Quality.
6.2.3.1 Reception
Use this menu to measure the reception quality
of each channel. If these are not optimal it is
possible that the picture and sound quality will
deteriorate in poor reception conditions and it
may be necessary to adjust the aerial. The
information refers to the 2 installed muxes for
the 3 channels.
The menu shows the channels numbers and frequencies of the 2 installed muxes.
Good reception quality requires a strong incoming signal. For more information on
the optimal signal strength see Chapter 8.2.3.2 Antenna Signal. It may be
necessary to adjust the aerial for optimal signal strength. The signal quality C/N
(Carrier to Noise) value is a measurement of the relationship between the aerial
signal and disturbance in the channel. This should be higher than 20 dB. The BER
(Bit Error Rate) measures the ratio of the number of faulty bits received to the
total number of bits received. The BER should be as low as possible and less than
2.00E-4 (2*10-4) to ensure good quality picture and sound.
If all the parameters for the incoming signal are good but there are still problems
with the picture or sound quality it is likely that there is a problem with the cable
that connects the TV / VCR to the MyM-3T.
