5.14.1 Analogue TV: Measuring the Video Carrier Level

In the measurement mode of analogue signals, the TV EXPLORER
monitor can work as an analogue indicator of level representing the signal present in the
input.

Out-channel measurement. Noise level is measured at f noise =
f tuning ± ½*Channel BW. To measure it correctly digital channel
must be tuned at its central frequency.
Modulation error ratio with noise margin indication.
BER measurement (Bit error rate) for the digital signal before
error correction (BER before FEC).
BER measurement (Bit error rate) for the digital signal after error
correction (BER after Viterbi).
Level measurement of the currently tuned carrier.
Ratio between the modulated signal power and the equivalent
noise power for a same bandwidth.
Automatic method.
Ratio between the modulated signal power and the equivalent
noise power for a same bandwidth.
Modulation Error Ratio. Complementary measurement of the
Noise Margin for DVB-S and the Link Margin for DVB-S2.
The BER measurement (Bit error rate) for the digital signal
before error correction (BER before FEC).
(Only for DVB-S) The BER measurement (Bit error rate) for the
digital signal after error correction (BER after Viterbi).
(Only for DVB-S2) The BER measurement (Bit error rate) for the
digital signal after error correction (BER after LDPC).
