content: This connector inhabits the backs of the switching cards in an HP 3488ahttp://www.testequipmentdepot.com/usedequipment/hewlettpackard/dataacq/3488a.htm.This particular card is a HP 44470A multiplexer. But most of the cards that fit into an HP 3488a have the same connector.From HP, there is a screw terminal block that connects here -- its like a card-edge connector that has an array of screw terminals to hook wires into. However, these terminal blocks are hard to come by second hand... everyone has these cards, but has lost the terminal blocks. So you're left with ... having to directly solder leads onto the multiplexer card? Not a great solution.I've looked for a replacement for these terminals, but I can't seem to find anything. I don't even know what (in general) they'd be called. Any suggestions?

content: I think this is the backplane: might go by other names toohttp://www.home.agilent.com/myagilent/faces/partDetail.jspx?partNumber=03488-66510text fixturehttp://www.home.agilent.com/myagilent/faces/partDetail.jspx?partNumber=03488-66501page 8-7Description General Purpose card ERC: 2709. MFr Part number 44471-66501Anyways, they have a lot of different part numbers for the text fixtures on the service manual (first document linked)Also 4485a terminal block is for a different device, maybe an HP03488 terminal block? they sure use a lot of different part numbers for the same thing!

content: maybe?http://www.artisantg.com/TestMeasurement/54268-2/Agilent_HP_44470_62101_Terminal_BlockThere are others too. google 44470-62101 agilentalso 44475-62101 agilenthttp://www.artisantg.com/TestMeasurement/63449-5/Agilent_HP_44475_62101_Termnal_Blockso pretty much part number minus the A and add 62101 to it.

content: The *-62102 parts are the correct ones. Perhaps they differ by pin number arrangement -- the multiplexer connects pairs of wires together while the general relay board simply connects one wire to another.I was hoping I could find an amphenol p/n that had the same connector spacing. After I'm off the 3488a's boards, i can connect up anyway that the connector dictates - solder, idc, etc etc.

content: Ok, I got my hands on the female end of this connector today.*Looks like a card-edge connector. Pitch: 0.156" (3.96mm). Card width: 0.062" (1.57mm). 44 Positions, 2 rows. Only 22 terminals are included in this connector though -- arranged in a zig-zag pattern from top to bottom.* (that's what she said)
