AR RF/Microwave Instrumentation has upgraded its line of laser-powered star probes with a new electric field probe, that replaces the previous model FL7018. The new model, FL7218, contains an internal microprocessor to provide linearization, temperature compensation, control and communication functions. The probe’s noise reduction and temperature compensation allow accurate measurements down to 2 V/m without zero adjustment. Microprocessor based linearization technology provides a 54 dB dynamic range. When rotated about its critical angle mount, the probe provides typical isotropic response of +/-1.5 dB to 18 GHz.Learn more from AR.
