March, 21, 2012. AR RF/Microwave Instrumentation says its new multi-tone RF test system can reduce radiated immunity testing from days to hours. The multi-tone system, the Multi-Star MT06000 (80 MHz to 6 GHz), includes all the necessary instruments to perform radiated immunity testing per IEC 61000-4-3 except for the required amplifiers, antennas, and directional couplers. Amplifiers are selected and sized based on your required field levels and testing needs.
The system mimics real-world threats with the ability to expose EUTs to more than one frequency at a time. By testing multiple frequencies simultaneously, a user is able to maximize efforts during dwell time to increase testing speed. The AR Multi-Star is capable of testing up to 10 frequencies at once. The number of tones that can be tested simultaneously is limited only by the signal-generator bandwidth (150 MHz) and the size of the amplifier.
The multi-tone software includes automated routines for field calibration and maximizing the test speed, while still maintaining the linearity and harmonic requirements of the standard. In the event of an EUT failure, thresholding or margin investigation and traditional signal-tone testing can be performed.
The MT06000 is available as a self-contained system or can be integrated with amplifiers and accessories into an automated test system. To learn more read Application Note #61, “Multi-tone Testing Can Save Both Time and Money.”
