Krohn-Hite Corporation 0.1Hz to 200kHz Single Channel Filter Model 3361

The Krohn-Hite 3361 Filter provides ease of operation and the reliability Krohn-Hite has been known for since 1949; along with a price that will fit any budget. The 3361provides a tunable filter with a frequency range from 0.1Hz to 200kHz; and with the 002 option, the range is extended to 0.005Hz. The frequency response characteristic is selectable to either maximally flat (Butterworth) for clean filtering in the frequency domain, or linear phase (Bessel) for complex filtering. The 3361 is selectable to function as a low-pass or high-pass, 4-pole filter providing a selectable input gain to 50dB, and an output gain to 20dB selectable in 0.1dB steps. The 3361 will accept input signals to ±10V peak at 0dB gain and has selectable ac or dc coupling. Memory is available for storing a set-up of the instrument which can be recalled with a simple command.
