16 differential signals mesurement

[paulArgentina]

Greetings from Argentina!, I'm using a NI USB-6218 to mesure 16 analog signals from floating surces, in differential mode. I have a practical problem, in order to avoid erratic results I must use 2 bias resistors to Ai GND for each signal, that means I need 32 resistors!???, We chose this ADQ device because we needed a compact adq system but using all this resistors si not practical at all. Do you have a simpler solution?, Is there any conexión accesoire that includes the resistors to GND?

Thanks and excuse my english...

NI could do a better job of promoting them! they are pretty sweet
