Product Overview

Rent Amplifier Research 125W1000 Amplifier (call for availability):


The Amplifier Research 125W1000 is a portable, self-contained, air-cooled, broadband, completely solid-state amplifier designed for applications where instantaneous bandwidth, high gain and linearity are required. Push-pull circuitry is utilized in all high power stages in the interest of lowering distortion and improving stability.


The Amplifier Research 125W1000, when used with a sweep generator, will provide a minimum of 125 watts of RF power. The Amplifier Research 125W1000 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 and a single rotary knob to offer status reporting and control capability. The display provides operational presentation of Forward Power and Reflected Power plus 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. Protection is provided by DC current level sensing of all output stages.


All amplifier control functions and status indications are available remotely in GPIB/IEEE- 488 and RS-232 hardwire and fiber optic, USB and Ethernet. The buss interface connector is located on the back panel and positive control of local or remote operation is assured by a key lock on the front panel of the amplifier.


Housed in a stylish, contemporary bench top enclosure, the Amplifier Research 125W1000 provides readily available RF power for typical applications such as RF susceptibility testing, antenna and component testing, watt meter calibration, and as a driver for frequency multipliers and higher power amplifiers. A safety interlock can be implemented via a rear panel connector.
