I would like put together a system with NI components that can measure the voltage on up to 500 different signals. I have limited bandwidth needs (10 MHz would be acceptable). I see that there is a 1x196 Multplexer (NI PXI/PXIe-2575) which I could use in conjunction with an SMU. However, I have more than 196 voltages to measure, so is there a recommended combination of multiplexers/SMUs to get to a larger number of channels?
