The 28612 Programmable Filter/Amplifier is a member of the Precision Filters 28000 family of analog signal conditioners. Designed for high frequency voltage measurements, the 28612 provides two channels of low noise programmable amplification and programmable low-pass filters with cutoff frequencies from 5 kHz to 3.15 MHz. Gain is programmable from x1 to x1000. Count on unsurpassed accuracy and channel to channel match for critical measurements. Up to sixteen 28612 cards may reside in the 28000 system to provide 32 channels per chassis.
The 28612 can be used to improve the signal-to-noise-ratio for high frequency measurements on resonant transduces and other sensors, particularly when large out-of-band energy limits the digitized dynamic range. When used as an anti-aliasing filter, the sharp selective response of the 28612 will maximize data bandwidth while providing greater than 80 dB attenuation of aliases. The 130 V per microsecond slew rate of the 28612 minimizes risk of distortion on high frequency edges of shock data. Excellent DC characteristics make the 28612 suitable for DC measurements, adding to the versatility of this amplifier.
