Tektronix 466 User Manual

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. 22).
Measure the
horizontal difference between the two
signals.
Multiply the measured difference by the setting of
the TIME/DIV switch; if sweep magnification is used,
divide this answer by 10.

Fig. 22. Time difference between two pulses from different
sources.
EXAMPLE: The TIME/DIV switch is set to 50 µs, the
MAG switch to X10 and the horizontal difference between
waveforms is 4.5 divisions (see Fig. 22).
Using the formula:

TIME COMPARISON MEASUREMENTS
If comparisons of an unknown signal with a reference
signal are
repetitious (e.g., on assembly line test) it is
possible
to otbain more accurate, easily read
measurements if the VAR
TIME/DIV control is adjusted to
set the reference signal to an exact number of divisions.
The
unknown signal can then be quickly and easily
compared with, or adjusted to, an exact number of
divisi_ons.
