Amplifier Research 500W1000B Amplifier - Unmatched Power and Precision
The Amplifier Research 500W1000B is a robust, self-contained, air-cooled amplifier engineered for demanding applications requiring instantaneous bandwidth and exceptional gain. This broadband, completely solid-state amplifier employs advanced push-pull circuitry in all high power stages, ensuring reduced distortion and improved stability. When paired with an RF sweep generator, the 500W1000B delivers a minimum of 500 watts of swept power, making it an essential tool for various testing environments.
Key Features:
- Digital Control Panel (DCP): Designed for both local and remote control, the DCP includes a user-friendly digital display, menu-assigned softkeys, a single rotary knob, and four dedicated switches (POWER, STANDBY, OPERATE, and FAULT/RESET) for comprehensive control and status reporting. The display provides real-time readings of Forward and Reflected Power, as well as internal amplifier status.
- Advanced Control Options: Featuring internal/external automatic level control (ALC) and front panel ALC threshold adjustment, the 500W1000B also supports pulse input capability and RF output level protection. An internal RF detector outputs for self-testing or operational modes.
- Remote Operation: All control functions and status indications are accessible remotely via GPIB/IEEE-488 format, RS-232 hardware, and fiber optic connections. The amplifier incorporates a keylock on the front panel to ensure positive control over local or remote operation.
- Stylish and Functional Design: Housed in a sleek contemporary equipment rack, the 500W1000B is ideal for RF susceptibility testing, antenna and component evaluation, watt meter calibration, and as a driver for higher-power amplifiers.
