3202R Krohn Hite Filter
The 3202R is a Filter from Krohn Hite. Electronic filters perform a variety of signal-processing functions with the purpose of removing a signal’s unwanted frequency components, enhance desired ones, or both. There are many types of electronic test equipment filters, including those that are passive, active, analog, digital, low pass, high pass, linear, and nonlinear. Linear filters are the most commonly used for most electronic equipment applications.
The Krohn-Hite 3202R Dual Channel Tunable Filter is an all solid-state variable rack-mounting electronic filter with low-pass, high-pass, band-pass, and band-reject capabilities plus continuous tuning range of 20 Hz to 2 MHz. The basic frequency response characteristic of this filter very closely approximates a fourth-order Butterworth with maximal flatness for cleanest filtering in the Frequency Domain. To meet the requirements of Time Domain, a switch changes the basic response to simple R-C to provide superior pulse or complex (transient) signal filtering. Pass band gain is unity and single-channel attenuation slope is 24 dB per octave. The individual channels may be interconnected to obtain band-pass and band-reject modes or to achieve 48 dB per octave high-pass or low-pass slopes.
