CW-350/CW-351

DSP Filter

High-sensitivity sensors are used to facilitate dynamic and precision acquisition of measurement data. Input channels on test benches, measurement technology or automation technology are often unable to carry out the required sampling rates, nor do they have filters to suppress interference signals or alias effects prior to digitizing signals. Both of the modules CW-350 and CW-351 make it possible to implement pre-filtering, signal conditioning and signal calculations with maximum flexibility.

A high-performance signal processor (DSP) makes it possible to implement variable low pass, high pass and bandpass filters, a wide range of different transfer functions and filter characteristics and filter orders.

For the purpose of maximum flexibility the processed data can either be output analog or via the CAN bus. Furthermore, it is possible to set predefined filters dynamically and according to the operating status via the CAN bus.
