Query only.
Unit returns the value of Eb/No (when in DVB-S or DVB-DSNG
mode), between 0 and 16 dB, resolution 0.1 dB.
Returns 99.9 if demod is unlocked.
Example EBN=12.3 (which is Eb/No = 12.3 dB)
For values greater than 16.0 dB, the reply will be: EBN=+016
Query only.
Unit returns the value of EsNo (when in DVB-S2 mode),
between 0 and 16 dB, resolution 0.1 dB.
Returns 99.9 if demod is unlocked.
Example ESN=12.3 (which is Es/No = 12.3 dB)
For values greater than 22.0 dB, the reply will be: ESN=+022
Query only.
Units returns the value of the estimated PER in the form ab x 10
. First three bytes are the value. Last two bytes are the exponent.
Returns 0.0E+00 if the demodulator is unlocked.
Example: PER=4.8E-03 (which is PER = 4.8 x 10
Query only.
Units returns the value of the estimated BER in the form ab x 10
First three bytes are the value. Last two bytes are the exponent.
Returns 0.0E+00 if the demodulator is unlocked.
Example: BER=4.8E-03 (which is BER = 4.8 x 10
