4-4. TM-40 Board Adjustment
8. Turn the SC PHASE knob of a signal generator SG2
slowly in the direction of _90d (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 0d (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 0d position.
12. Turn the SC PHASE knob of a signal generator SG2
slowly in the direction of _90d (2). The vectormoni-
tor waveform at the moment when the oscilloscope
CH-1 waveform appears in field 3, is defined as the
waveform C.

form D.
14. Confirm that [c = d].
