F. Oscilloscope Signal Waveforms
The osc i l l oscope plots are used for tro u b l eshooting the A1 D igital Sou rce. Note that
a l l the meas u rem ents are taken with a 1 0:1 probe. Other notes u n ique to a measu re
ment are written next to the waveform.
Service procedures described in this section are performed with
the protective co vers removed and power applied. Energy ava ilable
at man y poin ts can, if contacted, result in personal injury.
