The SAT threshold parameters are:
SAT Threshold - Edit:
Name: A text field describing the threshold template
Pre Viterbi BER:
Threshold level for bit error ratio before forward error correction
(Viterbi) – only for DVB-S
Post Viterbi/LDPC-BCH: Threshold level for bit error ratio after forward error correction
Minimum SNR: Threshold level for minimum signal to noise ratio (dB)
Minimum E
b
/N
0
:
Threshold level for energy per transmitted bit to noise power spectral
density ratio (dB)
Maximum EVM: Threshold level for maximum error vector magnitude (dB)
Minimum signal strength: Minimum threshold level for signal strength.
This is a measure of the stream signal power. It is expressed
according to the level mode selection made in the
Setup — ETR
view:
dBm: in decibels relative to a reference value of 1mW
dBμV: in decibels relative to a reference value of 1μV
dBmV: in decibels relative to a reference value of 1mV
Maximum signal strength: Maximum threshold level for signal strength.

Maximum frequency offset: Threshold level for maximum frequency offset (Hz)
Frequency offset zero adjust: Allows to define calibration adjustment for frequency offset (Hz)
