Troubleshooting
Unleveled Issues
9. If the external ALC loop is functioning properly the unlevel indicator should
not be on at this point and the signal level on the spectrum analyzer
should be somewhere near 0 dBm.
— If the signal level is not correct or the unlevel condition remains,
proceed to step 10.
— If the signal is at the correct level and there is no unlevel indicator,
the external leveling is working correctly at this frequency.
10.Referring to Figure 6-4, remove W32 from A7A1 J12 and connect W31 to
A7A1 J12:
— If the unlevel condition persists, replace the A7 Micro-Deck
assembly.
— If the unlevel condition goes away replace W32 and/or the A8 BNC
Bypass.
Due to the differences in the detector characteristics the signal level seen
on the spectrum analyzer screen at this time, even with the ALC leveled,
may not be as accurate as it would normally be.
