11 For each data point do the following:
12 Set the DCA to 100 mV/div, (0.5 / frequency) ps/div and delay listed in
depending on the model number under test.
13 Set the 83712B to the new frequency.
14 Adjust the 83712B until required input voltage is read on channel 2. Use a binary search to achieve
this result to within ±2 mV.
15 Set the trigger mode as required.
16 Use a marker to find the delay of the 2nd rising edge at 0 V currently on the screen.
17 Set the DCA to listed vertical and horizontal scale settings.
18 Set the DCA to the delay setting from
19 Setup the Histogram window to measure the RMS jitter in the center of the screen. Refer to the
histogram window information above.
20 Push the stop button, then the clear screen button, followed by the run button.
21 Let the DCA collect histogram data until there are 1000 or more hits.
22 After the 1000 hits have been collected then read the histograms standard deviation (this is the
RMS jitter reading).
23 Repeat Step 11 for each parameter in the specifications above.
24 Compare each parameter with the specifications above.
