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 Table 4-7 .
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 Step 13 .
16 Setup the Horizontal Histogram window to measure the RMS jitter in the center of the screen.
