DD2401 VME L-Band Demodulator Card Installation & Operational Manual Maintenance & Troubleshooting
MN-VME2401 – Rev. B 6-1
Maintenance and Troubleshooting 6
6.0 Periodic Maintenance
The DD2401 VME L-Band Demodulator Card requires no periodic field maintenance procedures.
Should a unit be suspected of a defect in field operations after all interface signals are verified,
the correct procedure is to replace the unit with another known working DD2401 VME
Demodulator card. If this does not cure the problem, wiring or power should be suspect.
There is no external fuse on the DD2401 VME Demodulator Card. The fuse should be located at
the external power supply.
