Abstract

The invention provides an agitator for a reverberation chamber device and a reverberation chamber device. The agitator adopts the form of a single-plate folding leaf. A field sensor calibration devicewith a field strength range above 1000V / m can be established by setting two sets of special-shaped single-folding leaves, so that the magnitude transfer and traceability of the high field strength measurement are realized, the accuracy of the field strength measurement of the electromagnetic environment is ensured, and the uniformity satisfies the limit requirement. In addition, the test requirements of medium equipment are met, and the size of the working area of the reverberation chamber is not less than 800 mm x 500 mm x 600 mm.

Description

technical field [0001] The invention relates to the field of electromagnetic compatibility, and more specifically, relates to a stirrer for a reverberation chamber device and a reverberation chamber device. Background technique [0002] For the calibration of field sensors from 1GHz to 18GHz, the IEEE Std 1309-2013 standard specifies the microwave and millimeter wave standard field method. The microwave and millimeter wave standard field method uses a signal source with stable frequency and amplitude and a calibrated standard gain antenna to establish a standard field that can be calculated in a fully anechoic chamber that simulates free space. Then place the field sensor to be calibrated in the established standard field to calibrate the field sensor. [0003] For the microwave and millimeter wave standard field method established by using the standard gain horn antenna and the full anechoic chamber, the calibration of field sensors in the lower field strength range can be...
