Problems solved by technology

Since domestic CTA, CMCC and other certifications require EMC testing, the EMC testing is a test of electromagnetic compatibility performance, mainly a test of harmonics, but the microwave anechoic chambers used by many domestic manufacturers to detect antenna microwaves only have OTA (over the air) test capability, and the OTA test is a test of the electromagnetic characteristic parameters of the mobile phone or tablet in the air. Many manufacturers do not have a microwave anechoic chamber for EMC testing, which brings great changes to the self-test.
[0003] At present, EMC testing can only be achieved by building a new EMC testing system or testing in advance to a third-party certification body, but both of these solutions require more money and increase certification costs.

Embodiment Construction

[0020] The specific implementation of the microwave testing system provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Please refer to figure 1 , is a schematic structural diagram of a microwave test system in the prior art.

[0022] Described microwave testing system comprises: computer 103; Comprehensive tester 105 and turntable 102 that are connected with described computer 103; Polarization switch 104 that is connected with described comprehensive tester 105 and computer 103; The connected antenna 102 ; the microwave anechoic chamber 100 , the turntable 101 and the antenna 102 are arranged in the microwave anechoic chamber 100 .

[0023] The microwave testing system can only test the electromagnetic characteristic parameters in the air (OTA test) for mobile phones or tablets, etc., but cannot detect harmonics.

[0024] Based on the above-mentioned microwave testing system for OTA testing, the present...

Abstract

The invention discloses a microwave test system, comprising a control end, a harmonic detection device and a turntable respectively connected with the control end, a first antenna connected with the harmonic detection device, an integrated tester, and a second antenna connected with the integrated tester. The microwave test system is low in construction cost and compatible with a test system for testing aerial electromagnetic characteristic parameters.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a microwave testing system. Background technique [0002] Many mobile phone and tablet manufacturers need to complete performance self-inspection before submitting their mobile phones or tablet computers for inspection, so as to ensure that they can successfully complete domestic CTA, CMCC, etc. certifications and obtain sales licenses. Since domestic CTA, CMCC and other certifications require EMC testing, the EMC testing is a test of electromagnetic compatibility performance, mainly a test of harmonics. However, the microwave anechoic chambers used by many domestic manufacturers to detect antenna microwaves only have OTA (over the air) test capability, and the OTA test is a test of the electromagnetic characteristic parameters of the mobile phone or tablet in the air. Many manufacturers do not have a microwave anechoic chamber for EMC testing, which brings great changes to th...
