Notes:
1. Unit returns ‘Not Installed’
for Rx options if unit is
modulator only.
2. Unit returns ‘Not Installed’
for Tx options if unit is
demodulator only.
Rx Es/No
N/A 4 bytes 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 (Es/No specified is 12.3 dB)
For values greater than 22.0 dB, the reply will be: ESN=+022
