Model 1000A225, M1
1000 Watts CW
10kHz–225MHz
The Model 1000A225 is a self-contained, air-cooled, broadband, completely solid-state amplifier designed for
applications where instantaneous bandwidth and high gain are required. Push-pull MOSFET circuitry is utilized in all high
power stages in the interest of lowering distortion and improving stability.
The Model 1000A225 is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the
amplifier. The DCP uses a 3-¾ inch diagonal graphic display, menu assigned softkeys, 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 automatic level control (ALC) with front
panel control of the ALC threshold and RF output level protection. RF Sample Ports are included to monitor forward and
reverse power.
All amplifier control functions and status indications are available remotely in GPIB/IEEE-488 format, and RS-232 hard
wire and fiber optic and USB. The bus interface connectors are located on the back panel and positive control of local or
remote operation is assured by a keylock on the front panel of the amplifier.
High-efficiency, universal-input, power-factor-corrected switching power supplies provide DC to all internal sub-
assemblies.
Housed in a stylish, contemporary enclosure, the Model 1000A225 provides readily available RF power for typical
applications such as RF susceptibility testing, antenna and component testing, watt meter calibration, particle accelerators,
plasma generation, communications and use as a driver for higher power amplifiers.
The export classification for this equipment is EAR99. These commodities, technology or software are controlled for export
