Analyzing waveforms
13.
Press the
Sync
button and wait
for a status of Not Counting (about
6 seconds). Depending on the signal
quality, you may need to press the Sync
button more than once.
Sync gets the oscilloscope synchronized to
the signal.
A status of
No Signal
status indicates that
the oscilloscope cannot detect the signal.
You may need to turn on the output of the
signal generator or AWG. A status of
No
Sync
may arise for Bit tests that require
a known pattern length, sync pattern, or
alignment character.
14.
Press the
Learn
button, if visible. Learn
only applies to some Bit Error Tests.
Frame, Symbol, and Character tests
do not require the learn operation.
Learn discovers the repeating pattern
in the signal and stores it into system
memory for comparison to the signal to
determine errors in the signal. Once a
signal is in memory, it remains there until
a subsequent Learn operation, so you
don’t have to use the Learn button every
time you start testing for errors.
15.
Press the
Run
button to start the error
detector.
If desired, you may press Stop or Reset at
anytime. After a Stop, you can press Run
again.
Run starts the Error Detector testing for
errors.
16.
Select the Results tab to see the results
of running the error detector.
NOTE.
The Serial Error Detector
automatically resyncs and resets all counts
to zero if you press
Reset
or disconnect and
then reconnect the signal.
