Abstract

The invention relates to a measuring device and method for radio frequency line transmission factors based on atomic energy levels. The invention aims to solve the technical problems of big measurement error and complex calibration processes in a conventional radio frequency line transmission factor measuring process. The method comprises the steps that alkali metal atoms generate an EIT spectrum by the action of two laser light sources; the EIT spectrum forms intersecting points of spectral lines by the action of a radio frequency electric field; a voltage value Vo, i of a radio frequency source is read and the electric field intensity value corresponding to one spectral line intersecting point is calculated according to Eo, i=Vo, i/d (d is the distance between parallel electrodes); the value is compared with a theoretical electric field value Ei to obtain a radio frequency line transmission factor ti=Ei/Eo, I corresponding to the intersecting point; by computing the average of the tis of different spectral line intersecting points, the precision of the radio frequency line transmission factor t can be further improved. Self-calibration measurement based on an atomic energy level structure is achieved; measurement does not require external equipment and is free from influence of external environment; the method is simple to implement.

Description

technical field [0001] The present invention relates to the technique of measuring the transmission factor of radio frequency lines, in particular to a measuring device and method for the transmission factor of radio frequency lines based on the atomic energy level. Background technique [0002] In the radio frequency signal transmission system, if the radio frequency transmission line and the signal source cannot be completely matched, it will cause signal reflection, interference, ringing effect, antenna effect, attenuation, superposition, etc. In the case of signal distortion, the measurement effect of the transmission factor of the radio frequency line is very important. [0003] At present, network analyzers are mainly used to measure the transmission efficiency of radio frequency lines. By connecting the two ends of radio frequency lines to the signal output terminal and signal receiving terminal of network analysis, the transmission efficiency of radio frequency lines...
