DBS-Band Gen IV Klystron High Power Amplifier for Satellite Communications D BS- Band The Gen IV High Power Amplifier Unmatched Efficiency Uses less power and produces less heat than any other K-HPA. Features Power Saver and Power Tracker, optimizing K-HPA efficiency to meet your operating condition. New Features and Options Scopescreen provides a graphical log display. The Ethernet Option provides higher speed connections, can update and coordinate all clock settings, and enables a snapshot feature where user can create a file containing all settings, alarms and faults at a single point in time. Greater efficiency and exceptional thermal margins have enabled CPI to design the smallest KPA on the market --- without the threat of overheating or a shorter klystron life. Acoustically Quiet The quietest K-HPA in the industry. Greater Reliability Low temperatures are the key to longer lifetimes for klystrons and electronic parts. The CPI power supply design and high efficiency, multi-stage depressed collector klystron make these lower temperatures possible. Worldwide Support Backed by over three decades of satellite communications experience, and CPI's worldwide 24-hour customer support network that includes fifteen regional factory service centers. Useful Displays Large, high quality, color, graphical display has a wide viewing angle and asharp appearance. All important functions are clearly displayed, and an event log is included. Integrated Protection Switching Redundant switch controller eliminates the cost of external controllers. System status is shown on the display and switch controls are implemented locally on the front panel touch-pad, or remotely via the digital serial interface. 811 Hansen Way P.O.
