The Krohn-Hite 3988 provides a tunable frequency range from 0.03 Hz to 1 MHz in the low-pass mode and 0.03 Hz to 300 kHz in the high-pass mode. Both modes are extended down to 0.003 Hz with the 002 option. The frequency response characteristic is either maximally flat (Butterworth) for clean filtering in the frequency domain, or linear phase (Bessel) to provide superior pulse filtering.
Each channel of the 3988 is an 8-pole, wide range, low-pass/high-pass filter or an amplifier providing gains to 70 dB in 0.1 dB steps. The 3988 will accept input signals of 10 V peak at 0 dB gain and has selectable AC or DC coupling.
Overload detectors are standard and assist the user in detecting input signals or incorrect gain settings. Ninety-nine groups of non-volatile memory for storage of front panel set-ups are stored in battery-backed CMOS which can be recalled with a simple command.
