N2744A Tek - Agilent adapter fix
(1/1)
EE-digger:
I bought two of these at work, new from Keysight, and on an MSO9254A and MSOX3104A, they were flakey as all get out.  I cleaned the pogo pins and the mating surfaces to no avail.  It seemed like they were too good to be true.

Once the probes communicated and setup, I had to be very careful not to move them at all.  This became tiring after a while and the adapters went on the shelf.

I took another look at them recently and opened them up out of curiosity.  What I found in both was that the two flat head screws left and right on the Tek side pcb were loose.  This allowed the contact pattern to flop around instead of being coaxially positioned.

They are now both solid.  I can wiggle and jiggle the adapter or probe without any response.  Only wish I had more of them for home  :-+

Kudos to the Keysight designers for these adapters and the pretty nice list of supported probes.  I've used them on P6245, P6249, P6247 successfully.

Another plus with these adapters is that some residual noise in our 1103 (internal ac version) was now gone.

Pics of the inside?

Oops.  I'll do that.

Reviving this thread (with pictures!) as I hit the exact same issue on an Agilent-branded N2744A where the internal screws were really loose and causing issues with the probe getting flaky or even being recognized or not intermittently, causing the scope to go nuts.

Below in order:
* T6 screws to open the case.
* 2 plastic pins to push in to unlock the other side of the case.
* General view.
* PCB coax assembly with the 2 PH1 screws that were loose and needed to be tightened.
