A.4.1 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.
