B.4.2 Error Performance

Raw BER

Command:
Response:

>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.

Corrected
BER

Command:
Response:

>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.
