The New Standard in EMC Test Performance

The Model 3170 Intell-I-Tune™ Antenna Solution sets a new global benchmark for MIL-STD-461 RS103 compliance across the 30–200 MHz range, uniquely delivering the required 200 V/m @ 1 meter from the fundamental frequency—not harmonics. This patented, algorithm-driven system also supports DO-160 and ISO 11452-2 testing configurations. Unlike traditional fixed-length antennas that suffer from narrow band performance and degradation across frequencies, Intell-I-Tune uses stepper motor-driven element tuning to mechanically optimize each antenna element for every test frequency and polarization. This results in optimal resonance across the band, ultra-low SWR (typically 1.5:1), and reduced amplifier strain, minimizing harmonic emissions by 25 dB or more.The smart auto-tune controller enables fast, precise, and hands-free tuning, storing frequency pro les and eliminating the need for technician oversight. The result: a powerful, efficient, and accurate test system that ensures confidence in your compliance testing.
