toolbar button to start a repetitive run again at the same frequency. Running at the same
frequency checks to see if the error message was caused by noise due to the changing of the
generator frequency.
10 If the analyzer displays an error again, lower the frequency by 1MHz and run again. If the test
does not display an error, increase the frequency by 1 MHz and run again.
11 Continue changing the frequency and running unit the frequency can no longer be increased and
the error message not displayed.
12 Set the generator to the highest frequency that did not cause an error.
13 Click Run Repetitive .
14 Wait for logic analyzer to complete 100 acquisitions at the new pulse generator frequency

MHz and then again wait for 100 acquisitions at this new frequency without any error. Repeat this
step until you get 100 acquisitions without any error display.
15 Click the Stop toolbar button to stop the data acquisition.
