ELECTRONIC MEASUREMENT APPARATUS
Video signal distribution amplifiers type WZ-22 and WZ-28.
Devices are designed to amplify video signals transmitted by coaxial cables on long distances . The amplifiers can be also used for signal level equalization in cable transmission lines of different leghts. Devices can be also applied as video signal distributors. Output signal level of WZ-22 and WZ-28 distribution amplifiers can be set independently in each channel. Thanks to this it is possible to tune the signal amplitude in certain points of the cable installation. The feature of gain redundancy of amplifiers make possible to use them as noise and interferences reductors in vision signals transmission systems. WZ-22 amplifier has one input and two outputs, while WZ-28 amplifier is it’s quad version - of four inputs and eight outputs. The WZ-28 model can be configured by user in several different modes - as for example: four independent, two output ports distribution amplifiers, one, six output ports distribution amplifier and one, two output ports distribution amplifier , one, eight output ports distribution amplifier.
