CAT-5 Video Variable Filters
It is often beneficial to use a video driver at the output of a video encoder for power savings, line driving, and additional circuit protection. The video driver is typically configured as an active filter, also known as a reconstruction or anti-imaging filter. The purpose of the reconstruction filter is twofold: it blocks the higher frequency components (above the Nyquist frequency) that were introduced into the video signal as part of the digitization process and provides gain to drive the external 75 Ω cable to the video display.

Variable Power Supply
VS-10a
The VS-10a power supply is a light weight, portable, non-isolated “variable source” from 0 volts to 150 Vac or 0 volts to 150 Vdc and rated for up to 10 amps, thus the name VS-10a. It is comprised of an illuminated voltmeter that reads to the first significant digit, AC variable system output voltage, DC variable system output voltage, logic output voltage and one sense (continuity) contact monitoring points. Banana jacks for connection of test leads are spaced at intervals that allow the use of dual banana test plugs if desired. The VS-10a is protected by two levels of overcurrent protection; AC input, and ground fault protection by a GFCI. All circuitry is housed inside a custom designed case made from 16 gauge steel. An Internal fan dissipates heat buildup and exhaust through louvered side vents built into the case. The carrying handle is designed with a “spring return to rest” position and is padded for comfort. The case has been sized for optimum portability and is balanced from the handle during transportation. The case has a powder coated finish that is scratch, chemical and weather resistant. Rubber padded feet support the case when in the upright position and a convenience receptacle is located on the side of the case.
