[volt-nuts] Fluke 5200A extender board.
5200A extender cables are a go! Connectors and boards are on order (from a different board fab in Hong Kong this time). One board goes on each end of the extender. Boards are connected by a 50 pin and 40 pin ribbon cable. ___ volt-nuts mailing list -- volt-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts and follow the instructions there.

Those are not holes... they are polarity markers on the silkscreen for the connectors. I do have one concern about doing the extender with ribbon cable. It is rated for 300V and three of the card slots do have 300V on them. ___ volt-nuts mailing list -- volt-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts and follow the instructions there.

Would that be at the maximum temperature? Service would be at room temp.

Re: [volt-nuts] Fluke 5200A extender board.
Hi Ken, I don't know if it helps but there's a 43/86 edge connector offered here for 14USD, (12USD for 5+).. https://www.surplussales.com/ComputerAccess/con_edge.html Single and double sided PCBs with 0.1 inch spaced strips were quite common at one time as part of the Veroboard range, some with gold plated edge connectors and some quite large, and it's possible these too might turn up as surplus. Not ideal for taking the double sided connectors but easy enough to bodge, albeit a bit time consuming. I thought I had some of the larger boards amongst my old prototyping stock but can only find 32 way single sided at the moment so the others seem to have gone already.

Re: [volt-nuts] Fluke 5200A extender board.
Hi Ken, Nigel is setting you on the right track with Vectorbord. I have used them for the edge connectors over the years with good results. I don't know if you are able to use Digikey of not but they list a 3690-26 ($80) that will be easy to modify to work for your project. I probably shouldn't have said that since I dont know how long you need the card extendor to be. If it is long enough it is not hard to saw (or mill) it twice to get the proper number of pins. I have a small mill available so I would use it. If i had to use my table saw it would be more of a challenge but it can be done. I usuallydon't need to glue the connector since it is largely self supporting. If it is a bit too loose for you it is easy to glue a plastic strip or two on the connector face. If you really screw up the connector you can replace it with the one Nigel found. Just use heavy wire wrap wire for any Adjustments. There are a few Vectorbord choices that would work for you. By the way, although Vectorbord is the correct spelling it is commonly spelled Vectorboard on the net.

Re: [volt-nuts] Fluke 5200A extender board.
Ken: I have a 5200 extender kit including the PC Board and the cables. In looking at it the center PC board that has the traces on it is enclosed on both sides with a piece of blank PC board material (no copper or traces) so you wind up with 3 ea 0.062 PC Boards riveted together. The center board has the necessary traces to connect the edge connector fingers to the socket. The outer two boards are just plain PC material with the necessary holes machined out so that the center board can have the connector and fingers open. There has been test points place on either side of the socket so you can connect a meter or scope to the lines. The connector has the following printing on it. 345-086-520-201 below that it has what looks like a trade mark of either a C or O with letters inside that which I can't make out, then 3A 250V EADC ?? the ?? means I can't read this. When you say photo copy the PC Board I will assume something that would show how the traces are laid out on both sides. This is impossible without removing the 5 rivets that hold this sandwich together which I don't want to do. I will do a PM to you with a pdf attached of the backside of the extender.

[volt-nuts] fluke 5200a extender board.
Hi all, Over the last 6 months I have been steadily repairing a faulty 5200A that I brought, it had numerous faults in the power supply regulator and power amplifier boards that I have managed to repair with a lot of difficulty as I do not have an extender board to operate the boards out of the chassis. I managed to overcome this by running numerous test leads to various points on the boards as I tested to enable me to take readings, but I have now got down to what looks like a problem on the attenuator board loading up the A7 power amplifier board and causing the +190 regulated supply to drop. The most likely cause is suggested as more than one attenuator path being selected at the same time, but I think it will be virtually impossible to trace the logic signals on and being supplied to the attenuator board without an extender board, so if anybody out there has one they are willing to sell please let me know! Alternatively it would be a great help if somebody could supply me with a full scale photo copy of both sides of the extender board so I can have a go at making one of my own. The 43/86 pin card edge sockets are no longer available as far as I can find out, the only company that lists any of them is Sullins Connectors but they are out of stock as well, so I cannot envisage them making any more in the near future, maybe somebody is parting out a 5200a? If I can make a pcb for the extender board then I think I can cobble up various parts to substitute for the card edge connector required. Thanks in advance for any replies.
