Product Overview

RENT Amplifier Research 125S1G4 (Call for Availability)

The Amplifier Research 125S1G4 is a portable, self-contained, air-cooled, broadband, and completely solid-state ampifier designed for applications that require instantaneous bandwidth, high gain, and linearity. Its push-pull circuitry is utilized in all power stages lowering distortion and improving stability.

Features and Specifications of the Amplifier Research 125S1G4 Amplifier include:

• Features:
• Provides a minimum of 125 watts of RF power when used with a sweep generator
• Digital Control Panel (DCP):
• Provides both local and remote control of the amplifier
• Uses a digital display:
• Provides operational presentation of Forward Power and Reflected Power
• Provides control status
• Provides reports of internal amplifier status
• Uses menu assigned softkeys
• Uses a single rotary knob
• Uses four dedicated switches: POWER, STANDBY, OPERATE, and FAULT/RESET
• Offers extensive control and status reporting capability
• Gain control and RF output level protection
• All control functions and status indications are available remotely in GPIB/IEEE-488 format, RS-232 hardwire and fiber optic, USB, and Ethernet
