Performance Verification
Trigger Jitter Test, Standard
Equipment List
• 83712B 20 GHz Synthesized CW generator opt 1E1, 1E5, 1E8, 1E9
• 11636B Power Splitter
• RF cables and adaptors as necessary
• DCA with an 83483A module in the left slot
Manual Procedure Connection Setup
1 Connect the 11636B to the RF output of the 83712B.
2 Connect one output of the 11636B to the front panel trigger input of the DCA.
3 Connect the other output of the 11636B to the channel 2 input of the DCA.
DCA Setup
4 Push the default setup button.
5 Turn off all channels except for channel 2.
6 Set the Horizontal Scale to 200 ps/div.
7 Set the trigger source to the front.

Take Measurements
8 For each data point, do the following:
9 Set the DCA to 100 mV/div, (0.5 / frequency) ps/div and delay listed in
10 Set the 83712B to the new frequency.
11 Adjust the 83712B until required input voltage is read on channel 2. Use a binary search to achieve
this result to within ± 2 mV.
12 Set the trigger mode as required.
13 Use a marker to find the delay of the 2nd rising edge at 0 V currently on the screen.
14 Set the DCA to listed vertical and horizontal scale settings.
15 Set the DCA to the delay setting from
16 Setup the Horizontal Histogram window to measure the RMS jitter in the center of the screen.
