[Test-Equipment] HP8640B Signal Generator Problem

[Jose V. Gavila]

Hello Scott,

Yes, it is not hard. There is a nice exploded view in the Service Manual.


>Any pointers or "gotcha's" I should know about, or is it just a 
>straightforward removal and replacement of that assembly?

Yes!!!. Beware with loose parts. If switch is failing, some tiny contact 
fingers could be loose. So check carefully for them inside the unit.

Please, let us know what you find.

Regards,

JOSE
