Bit Error 2
24. MS Loopback This field is used to enter or display amount of delay (expressed in number of speech
frames), before bits are compared. The Agilent 8922 uses this value to synchronize
to the correct received PRBS speech frame. The correct number of speech frames
can be determined automatically by making a Bit Error Test using Auto Mode when
the bit error ratio is approximately <20%. Then, if faster measurements are desired
or if the bit error ratio exceeds 20%, change the mode to manual.

23. Bits Tested
(Completed)
This field displays the number of bits that were tested during the last fully completed
test.
Bit error tests may extend beyond the number entered in the “Bits To Test” field so
that the last speech frame may be completed.
