Obtains the error rate for the signal found in the tuned
channel. After processing for a few seconds, the screen on
the PROLINK-4 shows the type of modulation, the MER
(modulation error ratio), and the BER (error rate) for the
digital signal before error correction (BER before FEC), the
latter two are shown in analogue form as a bar graph. The
instrument also shows the channel or frequency with the
corresponding deviation, the number of wrong packets
received during the measurement time (W.P.) and
information on the type of digital Multiplex detected
(MPEG2, Network, Provider, Bouquet) which appears
cyclically on the screen.
Obtains the error rate for the signal found in the tuned channel.
After processing for a few seconds, the screen on the
PROLINK-4 shows the type of modulation, the CSI (Channel
Status Information) and the BER (error rate) for the digital
signal after error correction (BER after Viterbi), the latter two
are shown in analogue form as a bar graph. The instrument
also shows the channel or frequency with the corresponding
deviation, the number of wrong packets received during the
measurement time (W.P.) and information on the type of digital
Multiplex detected (MPEG2, Network, Provider, Bouquet)
which appears cyclically on the screen.
Level measurement of the currently tuned carrier.
Video carrier to noise ratio (Auto or Referenced,
equivalent to terrestrial band, digital channels).
Automatic method.
Channel level to noise ratio (Auto or Referenced,
equivalent to terrestrial band, digital channels).
Obtains the error rate for the signal found in the tuned
channel. After processing for a few seconds, the screen on
the PROLINK-4 shows the type of modulation, the BER

Viterbi), the latter two are shown in analogue form as a bar
graph. The instrument also shows the channel or frequency
with the corresponding deviation and information on the
