Kenwood CS-5200 Series - Measuring Pulse J I T T E R

Pulse jitter
3) Set the H. MODE control to B. Measure the jitter width at the edge of the jitter.
The jitter is found by multiplying the j itter width by the reading of the B SWEEP
TIME/DIV.
Example : The j itter time is found by multiplying the j itter width by a reading of the B
SWEEP TIME/DIV. If the jitter width is 1.6 div and the reading of the B SWEEP
TIME/DIV is 0. 2 jus, the jitter time is found as shown below:
Jitter time = 1.6 (div)xQ.2 (jus) = 0. 32 jus
8 — 12 Measur i ng Phase Di fferences
With the dual-trace function, phase difference can be measured between, for example, two
sine wave signals of identical frequency.
1) Apply two signals to the respective INPUT terminals. Adjust the VOLTS/DIV and V. VARI
controls so that the two signals have identical amplitude.
2) Adjust the SWEEP TIME/DIV and H. VARI controls so that one period of the waveforms
is 8 div.
3) Use the y POSITION controls of both channels to bring the waveforms to the center
of the CRT.
4) Measure the horizontal distance between corresponding points on both signals. There
is a phase difference of 45 degrees for every division.
