Problem: Which C Series modules are available with anti-alias filters? Why does the NI 9215 module not have anti-alias filters? Solution: Currently the NI 9221, 9229, 9233, 9234 and 9239 C Series modules feature anti-alias filters. These modules are designed for very high-accuracy measurements for which anti-aliasing filters are a necessity. The 9215, however, is a more general-purpose module suitable for many applications that do not require anti-aliasing. The 9215 is a higher speed module at a lower price than the aforementioned modules with anti-alias filters. It is possible, however, to implement your own low-pass (anti-aliasing) filter external to the 9215 module with your own hardware. Additional information about low-pass (anti-aliasing) filters can be found in the related links section.
