Informationen
The Krohn-Hite Model 3901 programmable, two channel,
high-pass/low-pass elliptical Filter voltage gain Amplifier is one of a family of programmable Filter from Krohn-Hite.
As an elliptical Filter the Model 3901 has two independent Filter channels, one low-pass and the other high-pass,
allowing for band-pass operation with atunable cutoff
frequency range from 1Hz to 99kHz and a role-off rate of
115dB/octave.
Each Filter ection has aminimum stopband attenuation of
>80dB and apassband ripple oftypically
0.22dB. The 3901 provides either a single-ended or
differential input with a common mode rejection of >60dB.
Input gains up to 40dB in 10dB steps and output gains to
20dB in 10dB steps are also provided. The 3901 will accept
input signals of ±10V peak at 0dB gain and has selectable ac
or dc coupling. The Filter is GPIB bus programmable and is
complimented with non-volatile memory for storage of up to
99 front panel set-ups. Overload detectors are standard and
assist the user in detecting excessive input signals or
incorrect gain settings.
The 3901q is also a programmable voltage gain Amplifier for
applications that require a low-noise Amplifier The Amplifier has a bandwidth of 1MHz and gains to 60dB,
selectable in 10dB steps, and a wideband noise <100μν.
Typical applications for the Model 3901 are: distortion
measurements, separating specific bandwidths of information,
enhancing signal-to-noise ratio, low noise pre-amplification
and many more.
