Ratio between the modulated signal power and the equivalent
noise power for a same bandwidth. (according to TV standard)
Measure the frequency peak deviation for any modulated
analogue carrier in FM.
Channel power is measured assuming that power spectral
density is uniform throughout channel bandwidth.
To measure it correctly it is indispensable to define the
Channel BW.
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 before
error correction (BER before Viterbi).
BER measurement (Bit error rate) for the digital signal after error
correction (BER after LDPC).
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).
