configuration file. If asked to save the current configuration
file, click
No
.
2 Disconnect the U4203A Flying Lead Probe Set from channels 1 & 2 of the 81134A pulse
generator output (Bits 2, 6, 10, 14) and clock leads.
3 Connect the probe set from Pod 4 of logic analyzer to the pulse generator channels 1 & 2 output.
• Clock to Channel 1 Output
• Clock (NOT) Channel 1 Output (not)
• Bits 2 & 10 to Channel 2 Output
• Bits 6 & 14 to Channel 2 Output (not)
4 Open the
Sampling
tab in the Analyzer Setup dialog by clicking the

Icon.
5 In the clock assignment area, set Pod 1 Clock to
Don't Care
and set Pod 4 Clock to
Both Edges
.
6 Close the dialog window by clicking

.
7 Set the generator frequency to 357 MHz as a starting point.
8 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.
9 Start increasing the frequency on the pulse generator by 1 MHz increments while simultaneously
observing the logic analyzer data acquisition status.
10 Continue increasing the generator frequency until the logic analyzer displays an error that the
data could not be displayed, or the clock is too fast. It is possible that the error is caused by noise
introduced as the generator frequency is changed.
11 Without changing the frequency, clear the message by clicking OK. Then click the
Run Repetitive
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.
12 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.
13 Continue changing the frequency and running unit the frequency can no longer be increased and
the error message not displayed.
14 Set the generator to the highest frequency that did not cause an error.
15 Click
Run Repetitive
