AR 200TR4G8 (call for availability)The Amplifier Research (AR) 200TR4G8  is a self contained, forced air cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where instantaneous bandwidth and high gain are required. A reliable TWT provides a conservative 200 watts minimum at the amplifier output connector. Stated power specifications are at the fundamental frequency.The AR 200TR4G8 Amplifier’s front panel digital display shows forward and reflected output plus extensive system status information accessed through a series of menus via soft keys. Status indicators include power on, warm-up, standby, operate, faults, excess reflected power warning and remote. Standard features include a built-in IEEE-488 (GPIB) interface, 0 dBm input, VSWR protection, gain control, RF output sample port, auto sleep, plus monitoring of TWT helix cur, cathode voltage, collector voltage, heater cur, heater voltage, baseplate temperature and cabinet temperature.The modular design of the AR 200TR4G8 Amplifier’s power supply and RF components allow for easy access and repair. Use of a switching mode power supply results in significant weight reduction.The AR 200TR4G8 Amplifier is designed for 19 inch rack mounting, offers four side mounted carry handles, plus non-slip feet for bench top use. The AR 200TR4G8 Amplifier provides  readily available RF power for a variety of applications in Test and  measurement, (including EMC RF susceptibility testing), Industrial and University Research and Development, and Service applications.Features and Specifications of the AR 200TR4G8 Amplifier include:
