SDM-2020 Satellite Demodulator Remote Control Operation
Rev. 3 B–13
B.7 Error Performance Status
Raw BER Command:
Response: <add/RBER_'cr'
>add/RBER_xm.mE-ee'cr''lf'] Where:
x = < or > (data modifier to indicate that the error rate
is less than or greater than the returned value).
m.m = 1.0 to 9.9 (error rate mantissa).
ee = 1 to 99 (error rate exponent).
Notes:
1. The 'x' (< or >) parameter is only returned if the
error rate has exceeded the computational
resolution of the system.
2. 'No Data' is returned if the error rate cannot be
calculated.
3. 'Sampling' is returned if not enough data is
currently available to calculate the error rate.

Response: <add/IRES_'cr'
>add/IRES_tttt_xn.nE-ee’cr’’If’] Where:
tttt = 2047 (indicates type of error being read).
< or > (data modifier to indicate that the error rate is
less than or greater than the returned value).
n.n = 1.0 to 9.9 (error rate mantissa).
ee = 1 to 99 (error rate exponent).
Notes:
1. The x (< or >) parameter is only returned if the
error rate has exceeded the computational
resolution of the system.
2. “No Data” is returned if the error rate cannot be
calculated.
3. “Sampling” is returned if not enough data is
currently available to calculate the error rate.
This command returns the 2047 error rate (only available
when G.703 interface is installed. The IRE_command is
used to enable or disable the reading of the 2047 error. If
an interface other than G.703 is used, refer to the Non-
G.703 section.
