130 bytes
Query only
Unit returns the oldest 5 Stored Statistics, which have not yet been
read over the remote control. Reply format:
{CR}Sub-body{CR}Sub-body{CR}Sub-body{CR}Sub-
body{CR}Sub-body, where Sub-body=
AA.ABB.BC.CD.Dddmmyyhhmmss,
AA.A Minimum Eb/No during sample period
BB.B=Average Eb/No during sample period
C.C=Max. TX Power Level Increase during sample period
D.D=Average TX Power Level during sample period
ddmmyyhhmmss=date/time stamp
If there are no new events, the unit replies with RNS* If there are
less than 5 statistics to be retrieved, the remaining positions are
padded with zeros.
3 bytes
Query only
Unit returns the value of Eb/No, between 0 and 16 dB, Resolution
0.1 dB.
Returns 99.9 if demod is unlocked.
Example: EBN=12.3 (Eb/No=12.3 dB)
For values greater than 16.0 dB, the reply will be: EBN=+016
4 bytes
Query Only
Unit returns the value of the RX signal Level, in dBm, between –20
and –99 dBm, in the form: ccxx, where:
Cc=code
GT=Greater Than
LT=Less Than
= is equal to
xx=value (the '-' sign is implied)
Example:
RSL=LT99 (RX signal level is less than –99 dBm)
RSL===41 (RX signal level is equal to –41 dBm)
5 bytes
Query only
Unit returns the value of the estimated corrected BER in the form
-c
a.b x 10
. First 3 bytes are the value. Last 2 bytes are the
exponent. Returns 99999 if the demodulator is unlocked.
Example: BER=4.8E3 (BER = 4.8 x 10
