The NI USB-4431 DSA module is a new portable bus-powered dynamic signal acquisition (DSA) module and a suite of vibration sensors that are ideal for making high-accuracy vibration measurements required for noise, vibration and harshness (NVH) and machine condition monitoring applications. The USB-4431 DSA module acquires data at rates from 1 to 102.4 kS/s, which makes it possible to obtain a wide measurement bandwidth. The combination of the USB-4431 and the new vibration sensors, which include three accelerometers, a triaxial accelerometer and an impact hammer, gives engineers and scientists a complete stimulus response system from a single vendor for seamless product integration. The USB-4431 is a five-channel DSA module for making high-accuracy measurements from integrated electronics piezoelectric (IEPE) sensors. The module consists of four 24-bit simultaneously sampled analog input channels and one 24-bit analog output channel, which are ideal for stimulus response test systems. The USB-4431 also works well for a wide variety of field test applications such as frequency response audio tests and suspension shaker tests due to its portability…
