Time Difference Between Two Time-Related Pulses
(Basic 465B)
1. Obtain a Normal Sweep Display (refer to Basic
Oscilloscope Displays section
of this manual). Ensure
that the VAR TIME/DIV control is in the calibrated
detent.
2. Set the A TRIGGER SOURCE switch to CH 1.
3. Using probes or cables having equal time delays,
connect the reference signal to Channel 1 and the
comparison signal to Channel 2 inputs.
4. Depress the CH 1 and CH 2 VERT MODE push
buttons. Use either CHOP (in) or AL T (out) VERT
MODE switch, depending on the frequency of the
input signals. In general, CHOP is more suitable for
low-frequency signals, and AL T is best for high·
frequency signals. Center each of the displays
vertically.
5. Depress
the HORIZ DISPLAY A INTEN push button
and set the B (DLY'D) TRIGGER SOURCE switch to
STARTS AFTER DELAY. Set the B TIME/DIV
switch
20 times faster than the A TIME/DIV switch
(when possible)
to obtain the smallest usable
intensified zone. Observe intensified zones
on the
display (see Figure 28). Point A and Point B also
relate
to intensified zones on Figure 29.
6. Depress the ALT HORIZ DISPLAY push button and
release the CH 2 VERT MODE push button. Adjust
Channel 1 POSITION
and TRACE SEP so that A
Sweep
and B Sweep are displayed one above the
other. Use the DELAY TIME POSITION control to
move the intensified zone to the rising edge of a
CHANNEL 2
