Amplifier Research 20S1G4 The Amplifier Research 20S1G4 is a solid state, self-contained, air-cooled, broadband amplifier designed for applications where instantaneous bandwidth and high gain are required. It is housed in a stylish cabinet and designed forbenchtop use, but can also be removed for immediate equipment rack mounting.Features and Specifications of the Amplifier Research 20S1G4 include:

Features:

• Provides a minimum of 20 watts of RF power when used with a sweep generator
• RF input leveling circuit:
• Controls the RF input level to the RF amplifier first stage when the RF input level is increased above 0 dBm
• Protects the amplifier from RF input overdrive
• 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
• Digital display on the front panel indicates the operate status and fault conditions when an over-temperature or power supply fault has occurred
• Digital control for both local and remote control of the amplifier
• 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 connector on back panel
• Local/Remote switch on front panel assures positive control of local or remote operation
