Which instrument for arbitrary signal commutation (matrix)?

[Adgfsdg]

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.

I assume you already had a look at switches from NI.

You can also look at switches from Pickering.

Hi,

You might find this resource helpful when deciding between switch modules: http://www.ni.com/white-paper/14013/en/

Are you currently using any PXI based hardware?
