The Amplifier Research (AR) Model 100A250A is a self-contained, broadband Radio Frequency (RF) amplifier designed for laboratory applications where instantaneous bandwidth, high gain, and moderate power output are required. Solid state technology is used exclusively to offer significant advantages in reliability and cost. When used with a frequency-swept signal source, the AR Model 100A250A will provide 100 watts o f swept power output from .01 to 250 megahertz (MHz). Typical applications include antenna and component testing, wattmeter calibration, electromagnetic interference (EMI) susceptibility testing, use as a driver for frequency multipliers and higher power amplifiers, and use as an RF energy source for Magnetic Resonance Imaging (MRI) studies. The Model 100A250A can be operated locally by using the unit’s front panel controls, or remotely by using its built-in IEEE-488 or RS-232 interfaces.
