Query only.
Returns 3 values, with each parameter is separated by a colon, in the form x.xEx:y.yEy:z.zEz where:
x.xEx=total number of bit errors
yEy=total number of bits
z.zEz=value of the average BER or “No Sync” if no demod lock.
EXAMPLE 1: <0/BRA?
RESPONSE EXAMPLE 1: >0000/BRA=1.0E+03:2.2E+06:1.0E+03 (No Demod Lock)
