The Amplifier Research FL7018 Electric Field Probe 3 MHz - 18 GHz is a smart, fast, and extremely accurate that contains an internal microprocessor to provide linearization, temperature compensation, control, and communication functions. Noise reduction and temperature compensation allow accurate measurements down to 1 V/m without zero adjustment. Microprocessor based linearization technology provides a 60 dB dynamic range. When rotated about its magic angle mount, the probe provides isotropic response of + 1 dB to 8 GHz. The FL7018 is laser powered to allow for continuous operation without recharging or battery replacement. The FL7018 communicates through gl ass fiber optic cables, up to 100 meters long, to the FI7000 interface. X, Y, Z, and isotropic readings can be returned through an FI7000 in 20 msec.
