Cue And Rev Waveform Check; Check After Adjustment; Tracking Check - Sony CCD-F35 Service Manual

4-7. CUE AND REV WAVEFORM CHECK
1)
2)
(See Fig. 4-11.)
Play back the alignment tape for tracking adjustment and set
the REV mode. Confirm that waveform peaks maintain a
constant pitch of 5 seconds or more (See Fig. 4-11). In case
pitch is not constant, perform section 4-4. Tracking Fine
Adjustment and section 4-6. No. 7 Guide Adjustment.
Set the CUE mode. Confirm that waveform peaks still
maintain a constant pitch of 5 seconds or more (See
Fig. 4-11). Otherwise, perform section 4-4. Tracking Fine
Adjustment.

Tracking Check
Confirm that the amplitude of RF waveform is reduced to
approx. 3/4 when the track shift mode is set (See Fig. 4-12).
Then, confirm that the minimum amplitude value (EMIN) is
65% of the maximum value (EMax) or larger (See Fig.
4-13).
Confirm that no large fluctuations occur on the waveform
(See Fig. 4-14).
