CHECKOUT

TROUBLESHOOTING
The recommended troubleshooting level for the exciter is at the unit level. That is, if the
exciter fails to provide the transmitter system with a usable, modulated RF-drive signal and
all the exciter’s power, control, and signal inputs are normal, you should replace the exciter
with a spare.
