Dual Channel 4-Pole Filter
• Two Independent Filter Channels
One Band-Pass Channel
Attenuation: 24dB/Octave
Filter Modes: Low-Pass and High-Pass
Response: 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
Battery Operation Option
The Krohn-Hite Model 3362 Dual Channel 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 3362 two independent channels provide a tunable 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
Each channel of the 3362, offers selectable functions of low-pass
and high-pass 4-pole filtering with selectable input gains to 50dB
in 10dB steps, and output gains 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
Low-Pass Amplitude Response
With the Model 3362 the user can simply 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 are 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.
