Embodiment Construction

[0032] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] To test the radiated stray power ERP or EIRP of wireless products, the main test is the power radiated from the antenna end of the wireless product to the surrounding space, and the test cannot be carried out directly with the receiving antenna close to the product antenna, but at a certain distance. Measures the power transmitted from the antenna end of this wireless product. The power emitted by wireless products will inevitably attenuate within this distance, so accurate values ​​cannot be obtained. However, since the site is fixed, the receiving antenna and the cable between the receiving antenna and the receiver during the test are also fixed, so the attenuation and line loss of these sites are also fixed. The various attenuations between the wireless product to be tested and the receiver include: the spa...

Abstract

The invention relates to the test field of wireless products, and discloses a method and device for testing the stray radiant power of a wireless product. The method comprises the following steps: receiving a wireless signal of a to-be-tested wireless product through a signal receiver, and reading a power value Rn and a frequency value fn of the wireless signal, wherein the to-be-tested wireless product is placed at a position where a transmitting antenna is located during calibration and is in a normal working state; substituting the frequency value fn in a linear relation between a decay factor Fn and the frequency fn to obtain the decay factor Fn at the frequency; and compensating the decay factor Fn in the power value Rn to obtain a stray radiant power value of the to-be-tested wireless product: ERPn or EIRPn = Rn + Fn. The device for testing the stray radiant power of the wireless product disclosed by the invention comprises a receiving module, a calculation module and an output module. Compared with the prior art, the method and the device improve the test efficiency and reduce the manpower input and the site occupation time of the test item.

Description

technical field [0001] The invention relates to the testing field of wireless products, in particular to a testing method and testing device for the radiation stray power of wireless products. Background technique [0002] Now with the development of electronic technology, wireless products have been integrated into our lives. As the factory of the world, China undertakes a lot of research and development, production and export of electronic products. Wireless products exported to Europe and other foreign markets must undergo professional and rigorous testing, among which radiation spurious testing is the most difficult item for many wireless products to meet the standard requirements. This test item is relatively cumbersome, and many laboratories cannot complete this test item efficiently, quickly and accurately. [0003] The frequency is below 1GHz to test the radiation stray effective radiated power ERP (effective radiated power), and the frequency is above 1GHz to test ...
