Problems solved by technology

Therefore, this method cannot intuitively obtain the results we need, but can only be obtained after multiple calculations. The test efficiency is low, and it is not conducive to batch testing.
[0005] Therefore, the test process of the existing radiation stray power test method is very cumbersome, takes a long time, takes a lot of manpower, is inefficient, and cannot meet the requirements of batch testing, automated testing, and independent testing.

Embodiment Construction

[0022] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] The invention includes a method for testing the spurious intensity of radio frequency signal radiation of wireless products in a laboratory. refer to figure 1 and figure 2 , using the radiation spurious automatic test method of the present invention, when the radiation stray power of the object under test is tested, the object under test is placed on the test bench 2 of the anechoic chamber 1, and the object under test 4 is received by the antenna 3 under the working state The emitted electromagnetic wave signal is transmitted to the signal analyzer 6 by the coaxial signal line 5; the control computer 7 analyzes the received signal, detects the harmonics and intermodulation products and other spurious signals, and measures these spurious signals. The frequency and field strength of the stray signal; the conv...

Abstract

The invention relates to the field of wireless product testing, and specifically relates to an automatic test method for stray radiation. The automatic test method comprises the steps of receiving electromagnetic wave signals which are transmitted by a tested object in an operating state; analyzing the electromagnetic wave signals, detecting stray signals in the electromagnetic wave signals, and measuring the frequency and the field intensity of the stray signals; and finding out transformation parameters from a transformation parameter list according to the frequency and the field intensity, and calculating equivalent omnidirectional radiation power of the stray signals according to the transformation parameters. The automatic test method provided by the invention enables a stray radiation test to be more convenient and more efficient, the test efficiency is improved, and the labor input and the field occupation time of a test project are reduced.

Description

technical field [0001] The invention relates to the field of wireless product detection, in particular to a radiation stray automatic test method and a radiation stray automatic test device. Background technique [0002] Now with the development of electronic technology, wireless products are more and more widely used in our daily life and work, and the quality assurance of electronic products largely depends on the various detections, radiation stray Detection is one of the most important ones. This test item is relatively cumbersome, and many laboratories cannot complete this test item efficiently, quickly and accurately. There are two main methods for detecting radiation spurious in existing wireless products. [0003] The first is the substitution method. Each measurement needs to use an alternative antenna and signal source, and adjust the frequency and output power of the signal source so that the signal received by the antenna is equal to the frequency and field str...
