This high-performance anti-alias filter module can be used in either the CR9000X-series or CR9000-series Measurement and Control Systems. The CR9052IEPE's daughterboard provides current source excitation and ac coupling that allow the direct connection of Internal Electronics Piezoelectric (IEPE) accelerometers and microphones.

The CR9052IEPE includes 6 anti-aliased analog measurement channels with differential input ranges. Each of the 6 channels has its own programmable-gain instrumentation amplifier, pre-sampling analog filter, and sigma-delta analog-to-digital converter. An on-board digital signal processor provides real-time, programmable anti-alias filtering and down-sampling (decimation) before passing the results to the datalogger’s main processor.
