The Krohn-Hite Model 3940 programmable, dual channel, Butterworth/Bessel filter offers a programmable or benchtop filter covering a cutoff frequency range from 3 Hz to 2 MHz.
It has a frequency response characteristic of maximally flat (Butterworth) for clean filtering in the frequency domain, or linear phase (Bessel) to provide pulse signal filtering.
The passband gain is unity, and the attenuation slope is 24 dB/octave per channel.
The 3940 will accept input signals of ±4.5 V peak and provides input and output gains of 0 dB or 20 dB which can be selected via the front panel keyboard or over the GP-IB bus.
