Response to Query
Rx Signal
Level N/A 3 bytes Query only.
Unit returns the value of the Rx signal level, in dBm, between +3.0
and –99.0 dBm, where;
xxx is the Rx signal level.
Examples:
RSL=+03
RSL=-41
N/A RSL? RSL=xxx
Rx Frequency
Offset N/A 5 bytes Query only.
Unit returns the value of the measured frequency offset of the
carrier being demodulated. Values range from
± 0 to ± 30 kHz, 100
Hz resolution.
Returns 99999 if the demodulator is unlocked.
Example: RFO=+02.3 (which is + 2.3 kHz)
N/A RFO? RFO=sxx.x
Buffer Fill
State N/A 3 bytes Query only.
s=Defines which interface slot ( 1 or 2 )
c=Defines which channel ( 1 to 2 )
xx = value of the buffer fill state, between 1 to 99%. Returns 00 if
demodulator is unlocked.
Note: Command not valid for GbEI.
Example: BFS=1133 (which is 33%, on interface slot 1 channel 1)
N/A BFS?sc BFS=scxx
Rx BER N/A 8 bytes Query only.
Units returns the value of the estimated corrected BER in the form
a.b x 10
-c . 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
-3
)
N/A BER? BER=a.bEscc
