1 Select the Run Repetitive icon. Let the logic analyzer run for about 1 minute. The analyzer will
acquire data and the Listing Window will continuously update. A marker search window will
appear and show progress.
2 If incorrect data is found, the following window will appear. The data in the listing window should
be A's & 5's.
3 If the clock rate is too high, this error message may occur.
4 If either of these messages occur, the generator frequency should be lowered, Eye Scan should
be rerun, and the test should be rerun.
5 Lower the generator frequency by 1 MHz and rerun the test.
6 After the analyzer runs for about 1 minute, click the Stop button to stop the acquisition. If
the "can't find occurrence" window does not appear, then the analyzer has found good data.
7 For this Pod's Clock, record the generator frequency and the Data Rate in the "Maximum State
Data Rate" section of the “Performance Test Record" on page 77. Remember that the data rate is
twice the generator frequency.
