Tektronix 2205 Operator's Manual

Applications
More accurate phase measurements can be made by using the
horizontal magnifier function to increase the sweep speed with¬
out changing the SEC/DIV variable control setting. To do this,
set the HORIZONTAL MAG to X10.
With the sweep speed increased 10 times (MAG set to XI0), the
magnified horizontal graticule calibration will be 4.5° per division
(45°/division divided by 10). Figure 3-9 shows the same signals
illustrated in Figure 3-8, but horizontally magnified by a factor of
10 .
EXAMPLE. In Figure 3-9, the 10X magnified display results in a
horizontal difference of six divisions between the two signals.
Substituting the given values into the phase difference formula:
Phase Difference = 6 div x 4.5°/div = 27°,
