Amplifier Research 500W1000A Amplifier
The Amplifier Research 500W1000A Amplifier is a high-performance, air-cooled, broadband amplifier engineered for applications demanding instantaneous bandwidth and exceptional gain. Featuring a robust self-contained design, this solid-state amplifier employs advanced push-pull circuitry across all high-power stages, effectively reducing distortion and enhancing stability.
When paired with an RF sweep generator, the 500W1000A delivers a minimum of 500 watts of swept power, making it an ideal choice for rigorous testing environments.
Key Features
- Digital Control Panel (DCP): Provides extensive local and remote control with a user-friendly digital display, menu-assigned softkeys, a single rotary knob, and dedicated function switches (POWER, STANDBY, OPERATE, and FAULT/RESET).
- Operational Monitoring: Displays Forward Power and Reflected Power, along with real-time operational status and internal amplifier diagnostics.
- Gain Adjustment: Offers a gain control with a continuous adjustment range of 18 dB minimum, allowing fine-tuning to specific application needs.
- Internal RF Detector: Facilitated for self-testing or operational modes, ensuring optimum performance and reliability.
- Remote Control Capabilities: All control functions and status indicators are accessible remotely via GPIB/IEEE-488 format and RS-232, with a keylock mechanism for secure local or remote operation.
