Abstract

The invention relates to a test system and a power calibration method thereof. The test system comprises a control unit and a measuring unit; the control unit is coupled with a wireless module and controls the wireless module to emit a radio signal having preset power, wherein the wireless module is a calibrated wireless module; the measuring unit is coupled with the control unit and coupled with the wireless module through a radio frequency cable; the measuring unit is controlled by the control unit to set a measuring mode of the measuring unit; the measuring unit is used for measuring the radio signal to output a measured power value to the control unit; and the control unit adjusts the preset power according to a measured result; therefore, the power loss caused by the radio frequency cable can be compensated.

Description

technical field [0001] The present invention relates to a test system, and in particular to a test system of a wireless module. Background technique [0002] In modern times, wireless devices are used more and more frequently, thus improving the convenience of life. In each wireless device, such as a wireless mouse, a wireless phone or a mobile phone, a wireless module is configured to transmit wireless signals to a receiving end. Moreover, when the wireless module is performing quality control, it will go through a step of power measurement to measure whether the power of the wireless signal transmitted by the wireless module is accurate. [0003] Generally speaking, wireless signals decay quickly in the atmosphere, so measuring the power of wireless signals in the atmosphere will be very inaccurate. Accordingly, the transmitting end of the wireless module is generally connected to the measuring instrument through a cable. Since the attenuation speed in the cable is lower...
