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.

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 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)
