3500 Krohn Hite Filter


The 3500 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.

Additional Features:

The Krohn-Hite 3500 Band-pass Filter has both high and low cutoff frequencies independently adjustable over the range from 20 Hz to 200 kHz. The response characteristic approximates a fourth-order Butterworth with maximal flatness for optimum filtering in the frequency domain. For pulse signal filtering, a switch is provided to change the response characteristic to damped Low Q response for transient free filtering of pulse type signals. The calibration accuracy is ±10%, insertion loss is 0 dB, maximum attenuation is 60 dB, and features floating (ungrounded) operation.
