702 Tuning Voltage
1. Using an oscilloscope, check 10 MHz Synthesis line on P33–15. The signal period should be
100 ns with an amplitude of approximately 3V
pp
.
• If the signal is good, replace the A6 Frac–N.
2. If the signal is bad, turn the signal generator power off, remove the A6 Frac–N, and measure the
signal at P33–15 again.
• If the signal is good, replace the A6 Frac–N.
3. If the signal is still bad, measure P41–5 on the A7 Reference.
• If the signal is good, at P41–5, replace the A31 Motherboard.
• If the signal is bad on P41–5, replace the A7 Reference.
