Hakan,
Just to understand a little better, are you saying that other models have individual housings for each channel, with each of those housings mounted separately on the PCB?
Thanks,
Den

Hakan,
The ones I have on hand I believe were from a TDS540. The shield is one large die casting that attaches to the board. The shield presses 2 black plastic carriers that hold some sort of fuzzy metal ended pogo pins to contact the pcb at one end and each substrate at the other end.

I have a TDS784D where all four ceramic attenuator hybrids are cracked. I'm looking for replacements, and would like to know if any other models use compatible attenuators. Would the attenuators from a TDS744A work (even partially so I can check the rest of the scope)?
If anyone knows where I might be able to find them at a reasonable cost, I would love to hear from you. I'll take one with SPC problems since I know I can replace the relays.
----------------------
As far as I know all TDS's with the attenuator housing attached to the
Acq board use the same type of attenuators. However there are a whole
lot of versions used and I can't say what the differences are, possibly
bandwidth may be one. The ones with separate attenuator housing, e.g.
TDS520/540/544A etc. won't fit.

The early ones like the those I listed and also TDS620/640/644A had
a separate housing which contained attenuators for all four channels
and was connected to the Acq board with coaxes. These use a different
type of attenuator hybrids. I used to have a picture showing both
types side by side but can't find it now. The picture here
shows the attenuator used with
the newer type, i.e. with housing attached to the board.
