This Kemo VBF-8 series dual filter unit is still being produced in it's 5th generation unit called benchmaster. You can read about the use of this model unit in many prestigious papers published at major institutions the last few decades.

The VBF-8 is a dual filter unit, each configurable as either a low pass or high pass filter with a 3 digit dial in setpoint that covers .01Hz to 99.9Khz in range, using a 5 position range switch. It has an input impedance of 1Meg ohm, 2% cuttoff accuracy, low noise, two position gain switch, an output monitor for each unit, and a 50 ohm output. An additional function switch allows for the filters to be placed in series (for bandpass) and parallel (for notch filtration).

These are very high end units with remarkable performance.

In the video I introduce the VBF-8, walk you around the unit and demonstrate it's use in a couple of scenarios.
