Problems solved by technology

When the third harmonic energy of the radio frequency signal reaches the third resonance of the antenna, these useless harmonic energy will be radiated out, resulting in excessive spurious
For smart terminals, once there is a problem that the radiation spurious of the whole machine exceeds the standard, the positioning process is an extremely complicated and long stage. In many cases, there will even be a state that sometimes does not exist, resulting in the judgment and resolution of the problem. its unreasonable

Abstract

The invention provides an electronic equipment radiation stray source positioning method, which comprises steps: a conductive extension piece is additionally arranged on a to-be-positioned device of the electronic equipment; the radiation stray value of the electronic equipment is detected; the radiation stray value is compared with a predetermined value; if the radiation stray value is larger than the predetermined value, the device is judged to be the radiation stray source; and if the radiation stray value is smaller than the predetermined value, the device is judged to be normal. The electronic equipment radiation stray source positioning method can quickly find out the radiation stray source.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a method for locating stray radiation sources of electronic equipment. Background technique [0002] Radiation spurious, as the current mandatory certification index for electronic equipment, is the most complicated and difficult problem among all certifications. Especially for the GSM frequency band, because its own power is particularly high, it is easy to excite strong energy in an instant, which will cause the radiation of spurious harmonics to exceed the standard. In actual engineering, we also mainly encounter that the third harmonic of GSM900 is easy to exceed the standard, and the second or third harmonic of GSM1800 exceeds the standard. [0003] For radio frequency signals, the signals we transmit will not only contain usable signals (GSM900), but also often contain second (1800GHz) / third harmonic components (2700GHz). Most of the actual engineering is The...
