Small-Angle Phase Difference
Measurement
If the phase difference between the two signals being measured is
small, you can obtain an increased resolution for setting the cur-
sors by using the X10 Horizontal Magnify feature. To make a
small -angle phase difference comparison, use the following proce-
dure (see Figure 3-10):
