Amplifier Research 150A400 Amplifier
The Amplifier Research 150A400 Amplifier is a state-of-the-art, self-contained broadband amplifier crafted specifically for demanding laboratory environments. It excels in applications where instantaneous bandwidth, high gain, and moderate power output are essential. The innovative push-pull MOSFET circuitry significantly reduces distortion, enhances stability, and enables safe operation across a wide range of load impedances without the risk of damage.
When paired with an RF sweep generator, the AR 150A400 delivers a minimum output of 150 watts of swept power. Its user-friendly integrated digital display provides real-time information on operational status and alerts for critical fault conditions, including over-temperature and power supply issues. Once any fault is resolved, the unit can quickly return to operational status. The amplifier is equipped with advanced digital control systems for both local and remote functionality, featuring an 8-bit RISC microprocessor-controlled board that supports IEEE-488 (GPIB) and asynchronous, full-duplex RS-232 control of all amplifier functions.
Comprehensive remote control is facilitated via the GPIB/IEEE-488 format, ensuring a seamless interface for all amplifier control functions and status indications. A keylock on the front panel guarantees secure management of local or remote operations. The Amplifier Research 150A400 serves a variety of RF applications, including RF susceptibility testing, antenna and component testing, watt meter calibration, and functioning as a dependable driver for higher power amplifiers.
