Introducing the Amplifier Research 750W1000 Amplifier:
The Amplifier Research 750W1000 is an advanced, self-contained, air-cooled broadband amplifier that is expertly engineered for applications demanding instantaneous bandwidth and high gain. Utilizing push-pull circuitry in all high power stages, this amplifier is designed to minimize distortion and enhance stability, making it an ideal choice for rigorous testing environments.
When paired with an RF sweep generator, the Amplifier Research 750W1000 guarantees a minimum output of 750 watts of RF power, ensuring robust performance in various testing scenarios. Equipped with an intuitive Digital Control Panel (DCP), it offers both local and remote control capabilities via a color LCD touch screen and a user-friendly rotary knob. The DCP provides essential status reporting, displaying Forward Power, Reflected Power, and overall amplifier status, helping operators maintain optimal performance.
Key features of the Amplifier Research 750W1000 include a gain control setting, an internal automatic level control (ALC) adjustable from the front panel, and forward and reflective RF sample ports that facilitate precise power measurements. This amplifier is further protected by DC current level sensing in all output stages to ensure safe operation.
Remote control and status monitoring are accessible through GPIB/IEEE-488 format, RS-232 hardware, fiber optic, USB, and Ethernet interfaces. The back panel provides a buss interface connector, and a front panel keylock ensures secure local or remote operation. The compact design of the 750W1000 allows it to fit seamlessly into a single equipment rack.
This versatile amplifier can be used in various applications, including:
- RF susceptibility testing
- Antenna and component testing
- As a driver for frequency multipliers and higher power amplifiers
A rear panel connector is also available for implementing a safety interlock to enhance operational safety.
