I guess I have to amend my posting and apologize to HP. I misread the

drawing for the SMB connector and in fact these connectors are SMB. They are not "goofy". Also, I think I have located a 500 MHz plug-in for my 5245L counter. Now, if I could just find the extender cards to service the modules, I would be on my way to relatively painless trouble shooting of the 8443A. Repairs may be another matter.

Subject: RE: [hp_agilent_equipment] Hp-8443A Tracking Generator Problems I did call them GOOFY because that is what they are. They are goofy because I think the only place in the whole world they were used was the jacks and plugs for the cables of the connections between modules of the 8443A. They are not SMA, SMB, or SMC. I have looked at drawing of each of these types are the are not same as what HP used. I have no idea what they are or where to obtain them. I would certainly appreciate it if anyone could identify them along with a source of supply. As far as I am concerned their official description is "unobtainiun".

Subject: RE: [hp_agilent_equipment] Hp-8443A Tracking Generator Problems I didn't call them goofy, David Hallam (the OP) did. You and I are referring to what's more commonly called "Hybrid-D" connectors. (From context, I judge that David Hallam is thinking of the SMB (SMC?) plugs on the inter-assembly cables inside the instrument. The hybrid-D of interest in this thread actually has no standard D contacts at all, it's all coaxes. Which by the way are called "Size 8". Not to inundate you with 8's, but the connector pin layout is called "8W8", which predictably means 8 contacts 8 of which are coax.
