Analyzer kits measure modulated electric fields
Test & Measurement World Staff - September 18, 2012
Comprising an isotropic field sensor, glass fiber-optic cabling, a miniature tripod, and a processor unit, electric-field analyzer kits from AR RF/Microwave Instrumentation measure modulated electric fields, as well as CW (continuous wave) electric fields. The isotropic field sensor samples the composite field and transmits its amplitude digitally over optical fiber to the processor unit.
According to the manufacturer, the FA7000 series of analyzer kits delivers a sample rate of 1.5 Msamples/s—significantly faster than RF field probes—enabling it to accurately measure pulsed electric fields in the microsecond range. Each kit provides a web-based oscilloscope-type display of the instantaneous electric field strength (V/m over time) and calculates the minimum, maximum, and average field strength of the waveform as displayed.
Correction factors for many frequencies are provided with each kit and can be applied to improve the device’s amplitude accuracy. These factors are loaded and stored in the processor unit to automatically correct the field strength readings at user-specified frequencies.
