Compatible with select handheld analyzers, isotropic antennas employ tri-axis sensors, cover 9 kHz to 6 GHz range, and support Electromagnetic Field (EMF) radiation measurements to ensure wireless networks are in compliance with national standards for personal safety. Each of 3 sensors, positioned orthogonally inside antenna housing, transmit/receive spherical radiation pattern. Internal RF switch, MCU, and memory are controlled by firmware in Anritsu handheld analyzer via USB cable.
