KROHN-HITE 3944
The Krohn-Hite Model 3944 is a high-performance, 4-channel filter that redefines precision in signal processing. Offering both Butterworth and Bessel filter characteristics, this unit is perfect for applications demanding maximum fidelity and accuracy. Covering a remarkable cutoff frequency range from 3 Hz to 2 MHz, the 3944 allows you to tailor your filtering needs precisely to your specifications. Whether you require the maximally flat response of a Butterworth filter for clean frequency domain filtering or the superior phase response of a Bessel filter for optimal pulse and complex signal filtering, the Model 3944 excels in both scenarios.
This adaptable filter features a unity passband gain and a steep attenuation slope of 24 dB/octave per channel, making it ideal for a wide variety of applications. The input signal range of ± 4.5 V peak enables it to handle diverse signal types, while the selectable input and output gains of 0 dB or 20 dB can be easily adjusted via the intuitive front panel keyboard or over the GPIB bus for seamless integration into automatic test environments.
The Krohn-Hite 3944 is engineered for flexibility, allowing users to configure it in multiple ways: operate all four channels as high-pass or low-pass filters, use two channels for versatile band-pass or band-reject filtering, or combine various configurations for custom setups. When connecting the four channels, you can achieve an impressive 96 dB/octave of high-pass or low-pass filtering, elevating your signal processing capabilities.
One of the standout features of the Model 3944 is its 99 groups of non-volatile memory, allowing users to store and recall custom front panel setups with ease. These configurations are backed up by a battery-supported CMOS, ensuring your preferences are preserved. Additionally, the unit performs comprehensive self-test diagnostics upon power-up, checking its internal memory for any potential issues. In the event of a failure, the display promptly indicates which ROM or RAM component requires attention.
Applications for the Krohn-Hite 3944 are extensive, encompassing anti-aliasing, random noise testing, sound measurements, sound recording, and interference suppression in audio communications circuits, among many others.
