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.
