Amplifier Research 900S1G4 The Amplifier Research 900S1G4 is a portable, self-contained, air-cooled, broadband, completely solid-state ampifier designed for applications that require instantaneous bandwidth, high gain and linearity. The highly versatile 900S1G4 amplifier consists of three 350S1G4 sub-amplifiers housed in a single equipment rack with a controller. The 900S1G4 can function as one amplifier or be separated and operate as three separate 350S1G4A amplifiers which can be used independently. Features and Specifications of the Amplifier Research 900S1G4 Amplifier include:

Features:

• Provides a minimum of 900 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
• Provides a 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
• Buss interface connector is located on the 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
• Antenna/component testing
• Communication technology testing
• As a test instrument covering multiple frequency bands
• Suitable for communication technologies including CDMA, W-CDMA, TDMA, GSM, UWB,WiMAX etc.
