Earth Station SATCOM Satellite Dish Communications and Power Industries Inc. (CPI) - formerly known as Varian Electron Device Business, originated in 1948 as the founding technology group of Varian Associates. From it's inception in 1948 until August 1995, this group established itself under the Varian name as the world's technological leader in microwave and x-ray generating devices and in electronic equipment to drive these devices. In August 1995, the Varian Electron Device Business and it's six Divisions became CPI Inc., with the mandate to continue to grow it's tradition of technology, leadership, and manufacturing excellence.
