Page 60: Checking The Grating After Changing The Pickup Unit
Because of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may be seen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the average angle. • Hint Reloading the disc changes the clamp position and may decrease the "wobble". u163 DEH-P750MP/XN/UC http://www.xiaoyu163.com... - Page 61 3 7 63 1515 0 Ech → Xch 20mV/div, AC Grating waveform Fch → Ych 20mV/div, AC 0° 30° 45° 60° L 13942296513 75° 90° u163 DEH-P750MP/XN/UC http://www.xiaoyu163.com...
