The Video Separator is a signal booster & splitter that is used to take video input from a single source & direct it to two video outputs for monitors using analog signals. The signal boost obtained by using the VS-102 means that you can not only split the signal but to extend the distance so that you can send the signal to about 210 feet. This makes public broadcasts from a single computer very feasible. If you want to display the same information on many monitors at once, such as in a classroom environment, or at a demonstration, this product performs incredibly well. Bandwidth is the term that is used to describe the signal capacity of these units. In general, bandwidth is directly proportional to the amount of data transmitted per unit of time. Specifically, in analog signals, bandwidth is the difference between the highest-frequency & the lowest frequency components of a giving signal. For example a voice telephone signal has a bandwidth of 3000 Hz (or 3000 cycles per second), where an analog TV signal has a bandwidth of Approx. 6 M Hz (or 6 million cycles per second) which is Approx. 2000 times greater than a simple voice phone call. These units have a bandwidth of 250 M Hz (which is 250 million cycles per second) & that is almost 42 times greater than a simple TV signal. This huge bandwidth allows for the transmission of large amounts of information at a very high rate of speed, & thus you can use the very high resolution setting of 1600x 1200 in 24 or 32-bit true color mode at a refresh rate of 70 Hz. Please note: networking components such as switches, routers, UPS & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
