Applications
7. Adjust the TRIGGER LEVEL control for a stable display.
8
. Set the SEC/DIV switch to a sweep speed that provides three
or more divisions of horizontal separation between measure
ment points on the two displays. Center each of the displays
vertically (see Figure 3-7).
9. Determine the horizontal difference between the two signal
measurement points and calculate the time difference using
the following formula:
horizontal
SEC/DIV
difference
x
switch
Time
_ (divisions)______ setting
Difference
magnification factor
EXAMPLE. In Figure 3-7, the SEC/DIV switch is set to 50 pus per
division, HORIZONTAL MODE is set to MAG, and the MAG switch
is set to X I0. The horizontal difference between waveform mea
surement points is 4.5 divisions.
Substituting the given values in the formula:
Time
= 50 H-s/div x 4.5 div _
22.5
