This sale is for a Krohn-Hite 3362 Tunable Active Filter, Dual Channel with selectable HP/LP Butterworth Bessel. Foam packing fee still applies. · Filter Mode: Selectable Low-Pass and High-Pass · Response: Selectable Butterworth and Bessel · Input: Differential and Single-Ended · Input Gain: 0dB to 50dB in 10dB steps · Output Gain: 0dB to 20dB in 0.1dB steps The Krohn-Hite Model 3362 is a two channel filter. The 3362 provides a tunable frequency range from 0.1Hz to 200kHz. The frequency response characteristic is selectable to either maximally flat (Butterworth) for clean filtering in the frequency domain, or linear phase (Bessel) to provide superior pulse for complex filtering. Each channel of the 3362 is selectable low-pass or high-pass, 4-pole filter providing an input gain to 50dB, and an output gain to 20dB selectable in 0.1dB steps. The 3362 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. BAND-PASS/BAND-REJECT OPERATION can connect two channels in series to achieve band-pass operation or connect the two in summed parallel for band-reject operation. Applications of the Model 3362 is anti-aliasing, ultra-sound measurements, random noise testing, sound recording, suppressing interference in audio communications and related fields of medical, geological, geophysical, oceanographic, military and many more. The following specifications apply to each channel. Low-pass filter, high-pass filter. 2 and 4 channel models provide one and two channel (s) respectively of band-pass or band-reject via external connections. Type: 4-pole, Butterworth/Bessel. Tunable Frequency Range fc: 0.1Hz to 200kHz; (option 002, 0.005Hz). Frequency Resolution: 0.001Hz, 0.1Hz to 0.999Hz; 3 Digits, 1Hz to 200kHz, (option 002, 0.001Hz from 0.005Hz to 0.1Hz).
