content: Does anyone have the pin-out for the MSO6000A logic analyzer connector? Cable is part # 54620-61801which seems to be used on lots of Agilent analyzers.I thought this would be easy to find, but no luck so far...Thanks.Jay

content: By the way there is some circuitry inside the probes that is used to reduce loading and improve the frequency response(All passive). Something you might want to consider when making your own.

content: For whomever is interested: This cable is entirely passive. It surprised me quite a bit, because I always thought there would be a little amplifier in the problets. It seemed like there's a ceramic hybrid hidden inside. But it turns out there're only passives components on it. Below the proof.

content: I'm surprised it's twisted pair, but I think that's how the older HP 40 pin LA pods do it. The newer pods for higher frequencies actually use a microcoax from the connector body to the test point, then have a little RLC network for conditioning in the connector housing, but all the amplification and whatnot happens on the board in the LA.

content: The big cable from the scope is not twisted pair?Thought it was by how the cable looks woven around, but on the x-ray photos the wires look like they are just simply running straight. Or is there some sort of conductive thread surrounding the wires in the weave?

content: Ah now i see. Should have taken a closer look at them.So they run a smaller ground wire on each side of the signal wire to provide a good high frequency return path for each of them.

content: Drilled out the rivets. I did this to a damaged cable/pod assembly that I bought for parts. Wouldn't recommend doing it to one in good operating condition.

content: One of the prob was broken and got stuck inside the assembly. I finally managed to remove it by sharp tweezers and paper clip without opening the pod.Thanks!
