AR RF/Microwave Instrumentation has introduced the Model 350AH1 solid state amplifier. This portable, self-contained, 350 watt/10 Hz - 1 MHz unit provides power, durability and dependability along with the versatility for a wide range of applications.

Designed for test and other laboratory applications where instantaneous bandwidth, high gain and moderate power output are required, the potential uses for Model 350AH1 are many and varied. When configured for IEC 61000-4-16 testing, the 350AH1 functions as the RF section of the test setup, making it ideal for test levels 1 through 4, for Continuous Disturbance testing; and levels 1 through 3 for Short Duration Disturbance. In addition, the 350AH1 may be used to perform magnetic susceptibility testing defined by CS114 (4 kHz to 1MHz range) of MIL-STD-461F, antenna and component testing, watt-meter calibration, or as a driver for higher power amplifiers.

The unit has both over current and over-voltage protection to avoid damage. The RISC microprocessor controller board provides IEEE-488 (GPIB), USB, Ethernet and asynchronous full duplex RS-232 communication control of all amplifier functions.

Two 350AH1 amplifiers may be used together in a bridged output configuration by supplying the same signal to both amplifiers and using the internal signal inversion feature of one amplifier. The amplifier output grounds are connected and the load is placed across the two amplifier outputs.
