LeCroy Probus reverse engineering
Mechatrommer:
btw, i think it will take more than just a eeprom dump hack on a AP020 clone... :phew: (the edge mount BNC push-on connector and the 6 pin header can be seen here i'm also looking)
wingel:
I have found a supplier in China that can sell a push-on BNC connector similar to the one used in the LeCroy probes. It's their normal PCB edge mounted BNC connector without the coupling nut. The LeCroy connector seems to be about 12mm long, the connector I have found is about 17mm long, but if someone is making their own PCB it shouldn't be much of a problem. Since this is a product from China I don't know anything about the quality yet, hopefully it has decent 50Ohm impedance matching but you never really know until you actually have tested it.
I'm probably going to buy a few of these. With shipping, import duties and taxes the price should be less than EUR 5 per connector. I live in Sweden which is part of the European union. Is anyone else in EU interested in these connectors? Shipping and all the extra costs will probably be quite expensive, so I could buy a few extra connectors and resell them. For people outside of EU it's probably easier to just talk to the manufacturer.
As for the pin header, it seems to be a custom connector which one would have to get someone to manufacture specially. Probably rather expensive to do. But I think it might be possible to hack something together out of Mill-Max 5107 double tail header pins, an angled 2mm female pin header and some 3D-printed parts. :)
wingel:
One more thing. Could someone who has a LeCroy probe measure the pin header and post the exact dimensions. I'm trying to find a supplier who can manufacture the connectors just to see how much it would cost, and it would be nice to be able to give them some drawings of the part.
ollopa:
The mill-max connectors look nice (not the push-pin but standard gold plated round connectors).
I think LeCroy was smart in realizing that the ProBus connector would be plugged and unplugged many times during the lifetime of the scope, so they chose very high quality interconnects with a very smooth finish. I do worry that using budget square pin connectors with a rough finish may distort and damage the female headers on the scope, especially after repeated use. Anyway mill-max probably already has or can produce an adequate replacement connector.
For home use you don't really need to reproduce LeCroy's plastic housing and use right-angle connectors on the PCB. You could just have a straight header on a pigtail that gets pushed into the ProBus connector (just have to be careful about inserting it upside-down!)
