The NI 4551/4552 are high-performance, high-accuracy analog I/O instruments for the PCI bus. These instruments are members of the PCI-DSA instrument family and are specifically designed for demanding dynamic signal acquisition applications. The NI 4551 has two channels of 16-bit simultaneously sampled input at 204.8 kS/s and two channels of 16-bit simultaneously updated output at 51.2 kS/s. The NI 4552 has four channels of 16-bit simultaneously sampled analog input at 204.8 kS/s. Information on analog output applies only to the NI 4551, but information on analog input applies to both the NI 4551 and the NI 4552.  Both the analog input and the analog output circuitry have oversampling delta-sigma modulating converters. Delta-sigma converters are inherently linear, provide built-in brick-wall antialiasing/imaging filters, and have specifications that exceed other conventional technology for this application with regard to THD, SNR, and amplitude flatness. You can use these high-quality specifications and features to acquire or generate signals with high accuracy and fidelity without introducing noise or out-of-band aliases. Applications include audio signal processing and analysis, acoustics and speech research, sonar, audio frequency test and measurement, vibration and modal analysis, or any application requiring high-fidelity signal acquisition of signals with a bandwidth up to 95 kHz or signal generation with a bandwidth up to 23 kHz.
