High Resolution Phase Uitterence Measurement
(Figure 17)
For phase differences less than 45" measurement
accuracy may bo improved by using the PULL: X10 MAG
control as follows:
1. Perform steps 1 through 8 of the Dual Trace measure
ment procedures.
2. Center measurement points on the vertical graticule
line.
3. Pull the X 10 MAG knob. The sweep rate is now
4.5°/division (45°/division t 10).
4. Adjust the horizontal POSITION control to move
measurement points within the graticule area.
5. Measure horizontal difference (in divisions) between
corresponding points of the two waveforms.
6. Multiply horizontal difference by the magnified
sweep rate (4.5°/division>.
