Wireless Integrated Tester

Abstract

The invention provides a wireless integrated tester comprising a test circuit which comprises a master control unit and business modules of which working or testing is controlled or performed by the master control unit. The business modules comprise a test module which comprises transmitting unit modules and receiving unit modules. There are one or multiple transmitting unit modules and receiving unit modules which are independently arranged respectively. The transmitting unit modules and the receiving unit modules are proportionally arranged correspondingly according to testing time ratio of receiving units and transmitting units of devices under testing. According to the wireless integrated tester, the transmitting unit modules and the receiving unit modules are proportionally arranged correspondingly according to testing time ratio of the receiving units and the transmitting units of the devices under testing, and one or multiple transmitting unit modules and receiving unit modules are independently arranged respectively so that quantitative proportion of the transmitting unit modules and the receiving unit modules is flexibly configured according to different testing time of the transmitting units and the receiving units of different devices under testing so that maximum testing efficiency and highest equipment utilization rate can be realized.

Description

technical field [0001] The invention relates to a wireless testing instrument, in particular to a wireless comprehensive testing instrument. Background technique [0002] The comprehensive tester is a multifunctional instrument integrating the functions of various radio frequency instruments and conventional electronic measuring instruments. A comprehensive tester usually integrates conventional functions such as a frequency meter, a power meter, a radio frequency signal generator, an audio signal generator, a modulation meter, a signal-to-noise ratio meter, a digital voltmeter, a distortion meter, and some also have a spectrum analyzer, an oscilloscope, etc. , receiver, tracking signal source, signaling analysis, simulated base station, dedicated test mode and other functions.

Problems solved by technology

[0003] Existing wireless test instruments usually use a set of Tx+Rx circuits inside. With the advancement of technology and the improvement of integration, some wireless test instruments are put into two sets of Tx+Rx so that two sets of Tx+Rx can be tested on the spot. The wireless module of the device with wireless function is tested, but generally a set of Tx and Rx are usually set in pairs, and the set of TRx (transmitting unit) is independent, there is no between two sets of TRx (transceiving unit) associate

Due to the different working hours of Tx and Rx tests, the usage rates of Rx and Tx are generally different. For example, the time used by Rx (receive receiving unit) will be several times that of Tx (transmit transmitting unit). During the test, the Rx (receive receiving unit) circuit will be insufficient, and the Tx (transmit transmitting unit) will be idle for a part of the time

However, wireless test instruments are generally very expensive, and improving test efficiency and utilization of wireless test instruments is what manufacturers are most concerned about.

[0004] For example, when testing the wifi module of a wireless function device, the Tx of the DUT (device under testing) needs to calibrate the power accuracy. Usually, it is better to calibrate several power levels, while the DUT (device under testing) Rx does not need to be calibrated, just verify the test, and usually the time of calibration is several times that of the test, so the usage rate of the Tx module of the wireless test instrument will be relatively low (the wireless test is used when testing the Tx of the DUT The Rx module of the tester, the Tx module of the wireless tester is used when testing the Rx of the DUT); not only wifi, but for other wireless systems such as 2G, 3G, 4G, although both Tx and Rx need to be calibrated, the time difference is also large
