CPI 900W L-Band TWT System for Instrumentation Applications Model VZL2780P2 L- Band Compact Provides 900 watts of power in the 1.0 to 2.5 GHz frequency band in a compact 19-inch rack-mount multiple drawer configuration for wideband testing. Efficient and Reliable L-Band Employs CPI dual-depressed collector helix traveling wave tubes, increasing efficiency by a nominal 20% over conventional single collector TWTs, and a power supply designed with a minimum number of parts for maximum uptime. Simple to Operate Integrated microprocessor control lets the user adjust and monitor all operating parameters from one easy-to-read local or remote panel, using straightforward menu-driven commands. Includes a built-in interface and serial bus for operation from the station computer. Safety Conforms to international safety and EMC compliance standards. Easy to Maintain Worldwide Support Backed by over two decades of satellite communications experience, and CPI’s worldwide 24-hour customer support network that includes sixteen regional factory service centers. 45 River Drive Georgetown, Ontario, Canada L7G 2J4 tel: +1 (905) 877-0161 fax: +1 (905) 877-5327 e-mail: [email protected] www.cpii.com/emc 900W TWT High Power System Modular design provides for easy installation and maintainability in the field.
