5.14.1 Analogue TV: Measuring the Video Carrier Level

In the measurement mode of analogue signals, the PRODIG-3, monitor can work
as an analogue indicator of level representing the signal present in the input.
03/2008
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.
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.
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).
