(2) Press the CURSOR MODE switch to select the time and frequency mode. Align the AREF
cursor to the 101 point and the, A cursor to the 901 point. Read the measurement.
8 —11 Measuring Pulse Jitter
Pulse jitter with a relatively long cycle may be measured using the B sweep function.
1) Apply the signal to the INPUT terminal. Adjust the amplitude to 5 divisions with the
VOLTS/DIV and V. VARI controls. Set the VOLTS/DIV and H. VARI to CAL. Display the
waveform in an easy-to-see position with the SWEEP TIME/DIV control.
Press the x10 MAG switch if necessary.
2) Set the H. MODE control to ALT or AFTER' D. Adjust the B SWEEP TIME/DIV and DELAY
POSITION controls so that the pulse edge to be measured is intensity-modulated.
| NOTE
:
1
If the magnification of A sweep and B sweep is higher than several hundred
magnifications when the AFTER. D functin is used, delay jitter is produced. The
delay jitter level of the oscilloscope is less than 0.1 V at 100 maginifications.
