Hi Clive, The PCI card was not made by HP. see < http://control.etfbl.net/mjerenja/pci20428w.pdf > for the manual. It's a multi-purpose card so you need to know which inputs (or outputs) are used. The HP system description may help. Otherwise you will have to get someone with the adaptor to do a continuity check on it. Or play a guessing game. Put a 'scope on the main unit and see it it has analogue or TTL signals and start from there. Regards, Robert G8RPI.

I have bought the main unit, the 70420A test set, from the USA and have got this to work with an GPIB card. I have also bought a used PCI-20428W-1 digitizer card which the system recognises OK. My problem is that the card needs an adapter from the 50 way connector on the card to 2 SMA coaxial connectors which go to the test set. There is a picture of this in the installation manual which I have attached. Attempts to get information on this from Agilent have completely failed as they no longer use the PCI-20428W card, and the adapter is long since obsolete. If is has the adapter, does someone have photos of the inside of it, and/or perhaps trace the connections between the SMA connectors and the card connector. Once I have this information, I am sure I can make another adapter.
