© national instruments corp. 7 ni 9229e/9239e the ni 9229e/9239e analog input channels are floating with respect to earth ground and each other. The incoming analog signal on each channel is conditioned, buffered, and then sampled by a 24-bit delta-sigma adc. Each channel provides an independent sig...
Ni 9229e/9239e 8 ni.Com understanding ni 9229e/9239e filtering the ni 9229e/9239e uses a combination of analog and digital filtering to provide an accurate representation of in-band signals while rejecting out-of-band signals. The filters discriminate between signals based on the frequency range, or...

Ni 9229e/9239e 10 ni.Com stopband the filter significantly attenuates all signals above the stopband frequency. The primary goal of the filter is to prevent aliasing. Therefore, the stopband frequency scales precisely with the data rate. The stopband rejection is the minimum amount of attenuation ap...
