I would like to test a bunch of sensors. Each sensor has a DB15 connector with mixed digital and analog signals (bw ~5MHz, Z ~120R).
I am looking for an instrument where I can control which couple of sensors I would like to interconnect to the measurement PC. I've seen commutation switch such as the Keithley 3706A, but these guys does not accept custom commutation board when I can populate my own connectors and my own relays.
So I am thinking to make my own commutation system with a MCU, a FTDI and a bunch of analog switch and relays.
I feel this is a very common need in the testing area and I would like to know what commercial solution can be used in my case.
