Expanded sweep waveform d splay. Fig. 16. Measuling Small Phase Difference. A simple! Eethod of obtaining Brore accur- acy quickly is to siroply use X10 MAG for a scale factor of 4.5oldivision. Fig. 15. Phase Difference MeasrEeEent. Fo! the example shown iD Fig. 15, the horizontal distance is 1.? divisions. Thus, the phase differeDce is calculated as follows! Phase difference = 1.7 x 45o /div = 16.50 Metbod No. 2 (Refer to Fig, 16) The above procedure allows 45o per divi- sion, which l]1ay not give the dlesired accuraqy fo! small ...
