TIME DIFFERENCE BETWEEN TWO
PULSES FROM DIFFERENT SOURCES
(BASIC 466/464)
Make sure the VAR TIME/DIV control is in the
calibrated detent. Set the A
Trigger SOURCE switch to CH
1. Connect the reference signal to CH 1 and the com-
parison signal to CH 2. Connect the signals to the input
connectors using probes or cables with equal time delay.

Set the VERT MODE switch to either CHOP or ALT. In
general,
CHOP is more suitable for low-frequency signals
and
the ALT position is more suitable for high-frequency
signals. Center each of the displays vertically (see Fig.
29A).
Set the HORIZ DISPLAY switch to A INT and the B
Trigger SOURCE to STARTS AFTER DELAY. Set the B
TIME/DIV switch 20 times faster than the A TIME/DIV
switch (when possible).
