Product Overview

RENT AMPLIFIER RESEARCH 120S4G8 (Call for Availability)

The Amplifier Research 120S4G8 is a self-contained, air-cooled, broadband, solid-state amplifier designed for applications that require instantaneous bandwidth, high gain and linearity. 

Features and Specifications of the Amplifier Research 120S4G8 include: 

• Features:
• Provides a minimum of 120 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 graphic liquid Crystal 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 a dedicated on/off switch
• Offers extensive control and status reporting capability
• Special features:
• Gain control
• Internal/external automatic level control (ALC) with front panel control of the ALC threshold
• Pulse input capability
• RF output level protection
• Internal RF detector which provides an output for use in self-testing or operational modes
• All control functions and status indications are available remotely in GPIB/IEEE-488 format, RS-232 hardwire and fiber optic, USB, and Ethernet
• Bus interface connectoron back panel
• Keylock on front panel assures positive control of local or remote operation
• Low spurious signals, linearity, and load tolerance make it ideal for these various uses:
• RF susceptibility testing
