I happened to acquire two HP 3488A. They are called Switch/Control unit. That means that each of them can accept up to five different boards that do interesting things. There is a multiplexer, a matrix switch, a digital input/ouput board and so on.
Why would an HP 3488A be useful to me? Because it can be controlled through GPIB and can route signals.
Sadly neither board that I have is a multiplexer. I also do not have the back connector which means that the boards are a bit useless at the moment mostly because I haven’t been able to find the back connector.
So… I am just going to remove the back connector from my matrix switch board and build something. This way I could at least start to use the HP3488A.
Then I am going to remove more connectors and build myself a multiplexer board.
I think I am going to keep myself busy.
