Replacing a BNC input connector on a SR780 FFT analyzer.

[Jean-Pierre Coulon]

The big top lid is easy to remove. Then also the front panel and the disk
drive. Then I find a small shielded box with 6 BNCs.

It has a lid with 4 screws, the leftmost beeing blocked by the chassis.

Is the the right procedure?

Finally I succeded after removing the 3 large boards and unscrewing the 6
screws at the bottom of the cavity. Aftewards there are screws at the borrom
of the analyzer and you can pull the mother board which has right-angle
soldered BNCs.
