Introducing the Amplifier Research 1200A225A 1200 Watts CW
The Amplifier Research 1200A225A 1200 Watt CW is a solid-state, self-contained, broadband amplifier designed for applications where instantaneous bandwidth, high gain and linearity are required. The amplifier is air-cooled using internal self-contained liquid cooling for high performance and reliability. A stylish, contemporary enclosure allows for easy portability.
Key Features
All amplifier control functions and status indications are available remotely through the included Remotes Package. The Remotes Package includes GPIB/IEEE-488 format, RS-232 hardwire and fiber optic, USB, and Ethernet. The bus interface connector is located on the back panel and positive control of local or remote operation is assured by a Local/Remote key switch on the front panel of the amplifier. Also included with the Remotes Package is a safety interlock circuit for use with external safety switch interlocks. This circuit prevents the amplifier from going into operate mode unless the external connection is made. A jumper plug is provided for cases where this functionality is not needed.

Full VSWR–tolerant
CE & RoHS Compliant
Key Benefits
The Model 1200A225A, when used with a sweep generator, will provide a minimum of 1200 watts of RF power. Included is a front panel gain control which permits the operator to conveniently set the desired output level. The 1200A225A is protected from RF input overdrive by an RF input leveling circuit which controls the RF input level to the RF amplifier first stage when the RF input level is increased above 0dBm. The RF amplifier stages are protected from over-temperature by removing the DC voltage to them if an over-temperature condition occurs due to cooling blockage or fan failure. The Model 1200A225A is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the amplifier. The DCP uses a color LCD touch screen display to indicate the operate status and fault conditions if an overtemperature or power supply fault has occurred. The unit can be returned to operate when the condition has been cleared.

The CDG 7000 is a new test generator for all standards on immunity to conducted disturbances induced by high-frequency fields – including BCI tests (ISO 11452-4). One of the very few combined IEC 61000-4-6 test systems that contain the RF signal generator, an RF power amplifier, a 3-channel RF voltmeter, and a directional coupler at a very affordable price. IEC 60601-1-2 calling out IEC 61000-4-39 magnetic immunity for close proximity testing requirements can also now be met with the 10 kHz unit.
