Amplifier Research FA7000 Electric Field Analyzer 100 kHz – 60 GHz
Description
Amplifier Research FA7000 series of Field Analyzers represent a new patent-pending approach to more accurately measure modulated electric fields as well as CW electric fields. This innovative approach uses an isotropic field sensor to sample the composite field and transmit its amplitude digitally over optical fiber to a processor unit. The sample rate of the FA7000 Field Analyzer is 1 .5 million samples per second – significantly faster than conventional RF field probes – enabling them to accurately measure pulsed electric fields in the microsecond range.
Each of the FA7000 series analyzer kits 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. Each kit consists of an isotropic field sensor, glass fiber-optic cabling, and a processor unit. The processor unit stores all of the necessary amplitude corrections for its associated field sensor.
Correction factors for many frequencies are provided with each kit. These factors can be loaded into the processor unit to automatically correct the field readings at user specified frequencies. When correction factors are applied, the true accuracy of this device is realized.
