8. Set the A SEC/DIV switch to a sweep speed which
9. Position the displays and adjust the TIME (PULL)
VAR control so that one reference-signal cycle occupies
exactly 8 horizontal graticule divisions at the 50% rise-time
points (see Figure 20). Each division of the graticule now
represents 45° of the cycle (360° + 8 divisions), and the
horizontal graticule calibration can be stated as 45° per
10. Measure the horizontal difference between corre-
sponding points on the waveforms at a common horizontal
graticule line (50% of rise time) and calculate the phase
* horizontal
with a graticule calibration of 45° per division as shown
Substituting the given values into the phase difference
formula:
