Description

The Krohn-Hite Model 3944 is a 4-channel, Butterworth/Bessel filter offers a programmable or bench top filter covering a cutoff frequency range from 3Hz to 2MHz, with a frequency response characteristic of maximally flat (Butterworth) for clean filtering in the frequency domain, or linear phase (Bessel) to provide superior pulse or complex signal filtering. The passband gain is unity, and the attenuation slope is 24dB/octave per channel. The 3944 will accept input signals of ±4.5V peak and provides input and output gains of 0dB or 20dB which can be selected via the front panel keyboard or over the GPIB bus.
