Chapter 6: Replacing Assemblies
To remove and replace an acquisition hybrid
6–34
The Hybrid Connector
As shown in the illustration, two screws through the hybrid connector hold the bottom plate to
the underside of the PC board. If you remove the connector, the bottom plate can fall away from
the board.
Sometimes the plate will stick to the bottom of the board by itself because of adhesives that
fasten an insulator to the plate. If the connector is very gently removed and replaced, you might
be able to replace the connector without removing the ac quisition board. The key is to apply very
little pressure while removing the connector screws. Too much pressure will push the plate away
from the bottom of the board. If the plate falls from the board, you will have to remove the
acquisition board to re-install the connector. If the plate does not fall from the board, you will
have saved some time and work.
To replace a connector:
1
Remove the acquisition board from the instrument.
2 Follow the procedure for removing the hybrid.
