Krohn-hite 3800 narrow band tracking filter and manual
You are looking at one (1) Krohn-Hite Model 3800 Narrow Band Tracking Filter. The 3800 is a very narrow-band tracking filter with the unique ability to track without a reference signal. It can lock on and track an input signal buried 10 dB below the noise level. The Operating and Maintenance Manual is also included.
A quick review of the 3800's specifications:
1 Hz to 100 kHz frequency range
Selectable bandwidths from 0.001 Hz to 1 kHz
Locks on and tracks an input signal buried 10 dB below the noise level
Slope attenuation of 12 db per octave of bandwidth
Frequency response of a 4-pole Butterworth bandpass filter
Automatic gain control (AGC) over a dynamic range of 70 dB
Q factor as high as 100,000,000
Internal oscillator may be tuned separately or synched to center frequency
This item measures about 17 wide, 14 deep and 4 high. It is in very good condition with only a few very minor scuffs and scratches on the outer case. This filter was working when the lab closed. It does power on, but I do not have the necessary equipment to perform any additional testing. The filter requires a standard IEC power cord (not included).
