400S1G4 - AR Worldwide Amplifiers

AR Worldwide 400S1G4 Overview

The Model 400S1G4 is a self-contained, air-cooled, broadband, completely solid-state amplifier designed for applications where instantaneous bandwidth, high gain and linearity are required. Quadrature coupled circuitry is utilized in all high power stages in the interest of lowering distortion and improving stability. The Model 400S1G4, when used with a sweep generator, will provide a minimum of 375 watts of RF power. The Model 400S1G4, is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the amplifier. The DCP uses a digital display, menu assigned soft keys, a single rotary knob, and four dedicated switches (POWER, STANDBY, OPERATE and FAULT/RESET) to offer extensive control and status reporting capability. The display provides operational presentation of Forward Power and Reflected Power plus control status and reports of internal amplifier status. Special features include a gain control, internal/external automatic level control (ALC) with front panel control of the ALC threshold, pulse input capability and RF output level protection. Also included is an internal RF detector that provides an output for use in self-testing or operational modes. All amplifier control functions and status indications are available remotely in GPIB / IEEE-488 format and RS-232 hardwire and fiber optic.
