Amplifier Research 15S4G8A The Amplifier Research 15S4G8A is a self-contained, air-cooled, broadband amplifier designed for applications that require instantaneous bandwidth and high gain. It is housed in a stylish cabinet and designed for benchtop use, but can be removed for equipment rack mounting.Features and Specifications of the Amplifier Research 15S4G8A Amplifier include:

Features:

• Provides a minimum of 15 watts of RF power when used with a sweep generator
• Front panel gain control provides convenience of setting desired output level
• RF input leveling circuit:
• Protects the amplifier from RF input overdrive
• Controls RF input level to the RF amplifier first stage when RF input level is increased above 0 dBm
• RF amplifier stages are protected from over-temperature, due to cooling blockage or fan failure, by removing the DC voltage to them 
• Digital Display on front panel indicates operate status and fault conditions when over-temperature or power supply fault occurs
• Digital control for both local and remote control of the amplifier
• Control System is a 16-bit RISC microcontroller board:
• Handles primary functions of the amplifier
• Interprets commands sent to it from an 8-bit remote interface board:
• 8-bit microprocessor controlled board provides IEEE-488 (GPIB) and RS-232 control of all amplifier functions
• Expandable power technology provides upgradability
