Abstract

The invention discloses a wireless product edge signal measuring system based on IQxel and a method thereof. The system comprises a PC loaded with an ATE_Release automatic yield testing platform, an IQxel tester and one or more power divider which are in signal connection in order, wherein the one or more power divider is connected with a tested wireless product; the QMSL Qualcomm QLIB library function is loaded on the PC. Through a testing system and measuring method developed based on the wireless terminal tester IQxel and the QLIB library in a QMSL module in the Qualcomm QDART, the edge signal in the power signal can be effectively analyzed, so that the measurement of the edge signal is faster, and the testing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of production and manufacturing of communication electronic products, in particular to an IQxel-based method for measuring edge signals of wireless products. Background technique [0002] The test for the edge signal at the Wifi end is a very important measure. If the test fails, the Wifi product cannot be certified and cannot enter the mobile communication network. The so-called edge signal can also be said to be a stray signal, which refers to all the useless signals transmitted from the wireless product terminal except the transmission signal required for normal operation. If such a signal is too strong, it will cause interference to other surrounding systems. These cluttered signals are diffused into the surrounding space through media such as hardware circuit boards on the wireless product side. The edge signal has a wide frequency range, even up to 4GHz. [0003] By analyzing different types of products, it c...
