Softkey Menu Descriptions
Build User-Page Menu
Indicates whether the LOG ALARMS softkey is enabled or
disabled.
Displays either a Full Report or the User's Page results
selections at the end of the measurement period.
Indicates whether Squelch is ON or OFF.
Displays the current selection of the user-threshold that is used
to determine when output is logged.
Displays the trigger which, when it occurs will initiate logging
during the gating period. The selection is between log on error
seconds and log on the error ratio greater than a set threshold.
Displays the trigger which will initiate logging at the end of the
gating period. The selection is between always, error count non-
zero and error ratio greater than a set threshold.

Displays the time that has elapsed in the current gating period in
either normal or extra large characters.
Displays the number of one second intervals (since the start of
the gating period) for which the incoming and internal patterns
were out of synchronization.
Displays the frequency of the clock signal at the error detector
CLOCK IN port.
Displays the frequency of the clock signal at the pattern
generator CLOCK IN port.
The bit count is the accumulated count of clock bits since the
start of gating. Its value will normally be the running sum, but
will differ when:
Input gating has been applied, Block BER has been used to
window part of the pattern.
When a sync search has occurred with any mark density, zero
substitution or user pattern.
The bit count can be controlled by input signals to the error
detector front panel GATING INPUT. A TTL level low signal at
the GATING INPUT stops the error counters.
