Transducer level signals are usually in the mV range so they require amplification and filtering. Computer power supplies and circuits create a noisy environment. As a result, at least some of the system must be external. With the entire system provided, there are no matching problems to be solved. VXI offers attractive solutions for some measurement and control functions but is weak in a data acquisition application.
Noise is again a problem.
Components such as remote sensing of bridge excitation, effective normal mode filtering and protection against high frequency common mode noise. Adequate amplifier stability is sometimes neglected. You should know the approximate transducer output levels, the signal frequency and possibly the waveshape. The minimum sample rate can be based on aliasing considerations. Remember that sampling rate must be at least twice the highest frequency present.
