Amplifier Research 35S4G8A The Amplifier Research 35S4G8A 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 35S4G8A Amplifier include:
Features:
- Provides a minimum of 35 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
- Provides standalone performance for RF testing
- Can be configured to be used as a sub-amplifier in higher power amplifiers:
- Yet still be used as a standalone 35-Watt amplifier
- RF output connector must be configured to the rear panel to be used as a sub-amplifier
