Abstract

The application discloses an automatic test system and method for Bluetooth module radio frequency parameters. The system consists of a vector signal generator, a spectrum analyzer, a module fixture and a control master PC machine system. For a Bluetooth radio frequency module, testable items include carrier frequency offsets, error vector magnitude (EVM), transmitting power, transmitting power spectrum density, RSSI at 1 meter, and receiver sensitivity. A control master PC machine disclosed by the invention realizes cooperative control of multiple instruments based on a virtual instrument technology, also gives a friendly human-computer interaction interface, and is perfect in function and convenient to operate; the system can automatically retest to confirm for unqualified indexes; and thus the test time and human resources can be greatly saved.

Description

technical field [0001] The invention relates to the technical field of automatic testing based on virtual instruments, and more particularly relates to a radio frequency parameter automatic testing system and testing method for bluetooth modules. Background technique [0002] The development of automatic test system has gone through three main stages today. The first generation is a dedicated test system. The system itself is tailor-made for specific test requirements. It is mainly used for repeated tests with a large workload, to improve test speed or to be used in harsh environments that are difficult for testers to enter. Since there is no standard bus interface, the control computer and the test system are connected by a proprietary interface; the second generation is a desktop instrument building block type, and the emergence of standard buses such as IEEE488, VXI and PXI makes the main control computer communicate with multiple The test instruments are connected, and ...
