4. 3 2 Miscellaneous 3 2 1 Filter settings Filter concept of the C series 3 2 1 1 Theoretical background The filter setting is especially important in a signal sampling measurement system the theory of digital signal processing and especially the sampling theorem Shannon Nyquist state that for such a system the signal must be restricted to a limited frequency band to ensure that the signal has only negligible frequency components beyond one half of the sampling frequency Nyquist frequency Otherwise aliasing can result distortions which cannot be removed even by subsequent filtering A C Series device is a sampling system in which the sampling frequency which must be set in the configuration menu is subject to this constraint The low pass filter frequency selected thus hinges on how band limited the signal to be sampled at that rate is The control AAF for the filter setting stands for Automatic Anti aliasing Filter and automatically selects the filter frequency in adaptation to the sampling rate selected The rule this is based on is given by AAF Filter frequency 80 dB sampling frequency 0 6 Nyquist frequency 1 2 AAF Filter frequency 0 1 dB sampling frequency 0 4 Nyquist frequency 0 8 3 2 1 2 General filter concept imc C SERIES system architecture is actually a two step system in which the analog signals are sampled at a fixed primary sampling rate analog digital conversion with Sigma Delta A

DCs Therefore a fixed frequency analog low pass filter prevents aliasing errors to this primary rate The value of this primary rate is not visible from the outside depends on the channel type and is generally greater than or equal to the sampling rate which is selected in the settings interface The filter to be set is realized as a digital filter which offers the advantage of an exact magnitude and phase shift This is especially important for the sake of matching of channels which are jointly subjected to math operations If slow data rates f_sample are set in the system configuration then digital anti aliasing filters low pass filters ensure compliance with the conditions for the Sampling Theorem One distinguishes among three cases 3 2 1 3 Implemented filters Filter setting Filter Type without Only the analog anti aliasing filter matched to the primary data rate is in effect along with digital frequency response correction downstream which provides a steep frequency response This setting can be useful if maximum bandwidth reserves are to be used and there are theoretical limitations on the measured signal s spectral distribution which justify not performing total filtering Filter setting Filter Type AAF The digital anti aliasing filters are elliptical Cauer filters Their tight characteristic curve in the frequency range makes it possible to have the cutoff frequencies approach the sampling and Nyquist
