Parameter Type Protocol Description
Corrected
BER Command:
Response:
<add/CBER_'cr'
>add/CBER_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.
Corrected
BER Log Command:
Response:
Examples: <add/CBEL_'cr'
>add/CBEL_t.t;s1,s2,s3 ... sn'cr''lf']
[No new compiled data from last poll]
>add/CBEL_1.0'cr''lf']
[Momentary lock in 32 time intervals:
2.0E-3, 5.2E-7, 1.0E-10, <1.0E-12]
>add/CBEL_1.0;,,,,,,,2003,5207,1010,<
1012,,,,,,,,,,,,,,,,,,,,,'cr''lf']
Where:
t.t = Time between corrected BER samples in seconds ('0.1' to
'9.9').
; = At least one data point has been logged.
s1 to sn = Corrected BER samples in the format of (xmmee).
x = The optional data modifier '<' or '>' (less than or greater than).
mm = The corrected BER mantissa ('10' for 1.0 to '99 for 9.9).
ee = The corrected BER negative exponent ('00' to '99').
Error data (samples) are compiled at the nominal system rate
indicated by the time parameter (t.t). The samples are stored in a
thirty-two-element FIFO. When the 'CBEL_' command is
received, the samples in the FIFO are formatted and returned as
indicated. The FIFO is then flushed. If the FIFO becomes full, the
oldest sample will be lost as the current sample is written.
Notes: 1. The most recent sample is represented by 'sn' while
the least recent sample is represented by 's1'.
2.Data delimited by a comma (',') will be returned for all
time intervals logged.
3. The optional data modifiers '>' and '<' are only present
if the error rate exceeds the computational resolution of
the system.
