A14 L.O. Synthesizer Troubleshooting
— Verify the 4800 MHz input signal from the A16 Reference Assembly is stable
by pressing SPAN, 50 kHz, BW, 1 kHz. The signal on the functioning
spectrum analyzer should be very stable both in frequency and power as
shown in Figure 7-4.
— Reconnect the W6 cable to A14J200.
Figure 7-4 4800 MHz Narrow Span
NOTE If the 4800 MHz signal is not measuring the correct power level, see the “A16
