10. After the delta for the time histogram has been acquired (#
Samples = 100%), select the Result submenu.
11. Press MEAN and SIGMA. RECORD the values of sigma!
12. The RMS-jitter is calculated as follows:
13. The RMS-jitter for pulse width of 50 ns is 15.5 ps. Enter the
result in the Test Report as TR entry 4.3 - 1
14. Set HP 81130A for delay of 500 ns
15. Repeat steps 9 to 12
127(
TIME/DIV = 100 ps/div. Approximate delay = 530 ns
16. The RMS-jitter for pulse width of 500 ns is 20 ps. Enter the
result in the Test Report as TR entry 4.3 - 2
127(
Repeat the entire test for the second channel, if it is installed.
