Determine maximum clock rate
1 Switch to the Listing window by selecting the Listing tab
at the bottom of the main window.
2 Click the Run Repetitive toolbar button to start a
repetitive run on the logic analyzer for acquiring data
repeatedly.
Acquired data will start appearing in the Listing window.
3 Start increasing the frequency on the pulse generator by 1
MHz increments while simultaneously observing the logic
analyzer data acquisition status.
4 When the logic analyzer displays an error that the data
could not be displayed, decrease the pulse generator
frequency by 1 MHz.
5 Close the displayed error dialog by clicking OK.
6 Wait for logic analyzer to complete 100 acquisitions at the
new pulse generator frequency without displaying any
error. If an error is displayed, decrease the pulse
generator frequency by 1 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.
7 Click the Stop toolbar button to stop the data
acquisition.
