The Krohn-Hite 3360 Series provides a tunable frequency range from 0.1Hz to 200kHz, and with the 002 option, the range is extended to 0.005Hz. Each channel of the 3360 Series is a selectable low-pass or high-pass, 4-pole filter providing an input gain to 50dB, and an output gain to 20dB selectable in 0.1dB steps. Standard response types are Butterworth and Bessel. (read more)

The Krohn-Hite Model 3945 programmable filter provides one Butterworth channel of low-pass, tunable over the range from 170Hz to 25.6MHz; and two independent Butterworth or Bessel channels of low-pass, high-pass or bypass, one channel of band-pass or band-reject, tunable over the range from 3Hz to 2MHz.

The Krohn-Hite Model 3940 programmable, dual channel, Butterworth/Bessel filter is a GPIB/benchtop filter covering a cutoff frequency range from 3Hz to 2MHz. Attenuation slope is 24dB/octave per channel. The 3940 will accept input levels of ±4.5V peak. Pre and post-filter gains of 0dB or 20dB is also provided. All functions are front panel or GPIB bus controlled. (read more)

The Krohn-Hite Model 3955 programmable, dual channel, low-pass filter is the first dual low-pass programmable filter of its kind, covering the wide cutoff frequency range from 170Hz to 25.6MHz with 2 digits of resolution. The 3955 is a 4-pole, maximally flat (Butterworth) filter, with an attenuation slope of 24dB/octave and a stopband attenuation of >100dB referred to 1Vrms input. (read more)

The Krohn-Hite Model 3944 is a 4-channel, Butterworth/Bessel filter providing GPIB/benchtop filtering covering a cutoff frequency range from 3Hz to 2MHz. Passband gain is unity, and the attenuation slope is 24dB/octave per channel. The 3944 will accept input signals of ±4.5V peak providing input and output gains of 0dB or 20dB selectable via the front panel keyboard or the GPIB bus. (read more)

The Krohn-Hite Model 3988 provides a tunable frequency range from 0.03Hz to 1MHz in the low-pass mode and 0.03Hz to 300kHz in the high-pass mode. Both low end frequency cutoff is 0.003Hz with the 002 option. Each channel of the 3988 is an 8-pole, wide range, low-pass/high-pass filter or an amplifier providing gains to 70dB in 0.1dB steps.
