Fast Bit Error
10. MS Loopback
This field is used to enter or display the Round Trip Delay (RTD) of the mobile
(expressed in number of TDMA frames), before bits are compared. The correct
number of TDMA 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.
Choices
Burst Delay - range 0 through 26.
Manual
Auto
When Compatibility Switch mode is used (refer to Chapter 3,
Using Compatibility Switch), two additional fields appear under
the new heading
Loopback
.
Bit Error measurements are not automatic when in
Compatibility Switch mode. The additional fields allow manual
control of test loop commands to the mobile. When selecting
Off
, an open test loop command is sent to the mobile and
selecting
FAST
sends a close test loop command.

11. Run/Stop
(Control)
Run starts a bit error test. Stop discontinues the bit error test in progress.
12. Single/Cont
(Control)
Single allows one test to be performed. Cont allows testing to automatically repeat.
13. % BE Ratio
This field allows you to select between a display showing the percentage of errors
(select
MHz
) and ppm (select
W
) which gives you the errors in parts-per-million.
