Turn the SC PHASE knob of a signal generator SG2
slowly in the direction of
_
90
d
(
2
). The vectormoni-
tor waveform at the moment when the oscilloscope
CH-1 waveform appears in field 3, is defined as the
waveform A.
9.
Turn the SC PHASE knob of a signal generator SG2
slowly in the direction of 0
d
(
3
). The vectormonitor
waveform at the moment when the oscilloscope CH-1
waveform appears in field 1, is defined as the wave-
form B.
10. Adjust RV1202 and repeat steps 7 through 9 until the
specification [a = b] is satisfied.
11. Return the SC PHASE knob of a signal generator SG2
to the 0
d
position.
12. Turn the SC PHASE knob of a signal generator SG2
slowly in the direction of
_
90
d
(
2
). The vectormoni-
tor waveform at the moment when the oscilloscope
CH-1 waveform appears in field 3, is defined as the
waveform C.
13. Turn the SC PHASE knob of a signal generator SG2
slowly in the direction of 0
d
(
3
). The vectormonitor
waveform at the moment when the oscilloscope CH-1
waveform appears in field 1, is defined as the wave-
form D.
14. Confirm that [c = d].
