Description of arguments
(note that all arguments are ASCII numeric
codes, that is, ASCII codes between 48 and 57)
affect this value. Example reply: NUS=198
Query only.
Unit returns the value of Ebi/No, between 0 and
16dB. 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 vaue of Coarse AGC setting,
between 0 and 99
Example: AGC=76
Query only.
Unit returns the value of freq. offset of the carrier
being demodulated. Values range from ±0 to ± 30
kHz, 100 Hz resolution.Example: RFO=+02.3
(offset is +2.3 kHz) Returns 99999 if the demod is
unlocked.
Query only.
Unit returns the value of the buffer fill state. Values
range from 1 to 99% .Example: BFS=33 (buffer fill
state is 33%) Returns 00 if demod unlocked.
Query only.
Unit returns the value of the estimated corrected
BER in the form a.b x 10exp-c. Fist and second
bytes are value, 3rd and 4th bytes are the
exponent. Returns 99999 if demod is unlocked.
Example: BER=4.8E3 (BER is 4.8 x 10-3)
Query only.
Returns the redundancy state of the unit, where:
