Amplifier Research 1000A225 Amplifier – Unmatched Performance
Introducing the Amplifier Research 1000A225, a cutting-edge self-contained, air-cooled, broadband amplifier meticulously engineered for high-demand applications requiring instantaneous bandwidth and elevated gain. This amplifier is ideally suited for RF susceptibility testing, antenna and component testing, watt meter calibration, particle accelerators, plasma generation, and communications.
Advanced Circuit Design
Constructed with push-pull MOSFET circuitry throughout its high-power stages, the 1000A225 effectively reduces distortion while enhancing stability. You can expect a seamless performance that meets the rigors of demanding environments.
Digital Control Panel (DCP)
Equipped with a Digital Control Panel, users benefit from both local and remote operation. The DCP features a 3¾-inch diagonal graphic display, menu-assigned softkeys, a single rotary knob, and four dedicated switches for POWER, STANDBY, OPERATE, and FAULT/RESET functions. The display offers real-time operational insights, including Forward Power, Reflected Power, and internal amplifier status reports.
Versatile Monitoring and Control
The Amplifier Research 1000A225 comes with gain control and an internal automatic level control (ALC) featuring front panel adjustment options. Users can monitor RF performance through RF Sample Ports for forward and reverse power, while all amplifier control functions and status indications are also available remotely via GPIB/IEEE-488 format, RS-232, fiber optic, and USB connections. A keylock on the front panel ensures secure control for local and remote operations.
High-Efficiency Power Supply
The amplifier is powered by high-efficiency, universal-input, power-factor-corrected switching power supplies, providing excellent DC power to all internal subassemblies.
