The AAF-2 is a multi-channel low-pass filter board designed for use in front of A/D converters with resolution up to 16-bits. testing, ultrasonics, acoustics, structural analysis, industrial, test, scientific and laboratory data collection and applied mechanical applications in electronics, aerospace, field research, automotive, and process control industries.
The AAF-2 protects and filters 2, 4, 6, or 8 differential analog channels.
Each 2-channel pair is available with any one of 8-pole Cauer, Bessel, Butterworth, or linear phase filters.
The cutoff frequency of the AAF-2 is set by an on-board potentiometer, which sets the same cutoff frequency for all filters on the board. Optionally, the cutoff frequency can be controlled with an external clock source for tracking filter applications, very low cutoff frequencies, or other special purposes.
Connection to Your Data Acquisition System All I/O connections from the AAF-2 are made via two high density DSUB 26-pin triple-row connectors that extend out of the rear of the computer.
