The Amplifier Research FP5080 is a battery-operated broadband Isotropic Electric Field Probe designed for use in
Radio Frequency Interference / Electromagnetic Compatibility (RFI / EMC) test system applications. This probe
uses optical isolation to minimize field perturbation during measurements.
The Amplifier Research FP5080 probe assembly consists of a spherical casing, containing the sensor, which is
mounted on one end of a shaft; the other end of the shaft is attached to an extrusion which houses the electronics. The sensor and electronics housing operate - and are calibrated - as a unit.
The Amplifier Research FP5080 measures the field strength in each of three axes. It performs a vector addition
calculation on the readings and sends the resultant to the receiver via a fiber optic cable. Frequency response of
the Amplifier Research FP5080 is 80 MHz to 40 GHz; dynamic range is 1 to 300 Volts per meter (V/m).
