Embodiment Construction

[0017] The application software of the present invention includes bar code scanning application software, sensitivity test application software, power test application software, waveform analysis application software, throughput test application software, database generation application software and the like. These applications run on the standard Windows operating system. image 3 It is a block diagram of the overall flow of the software. Its workflow is as follows: After the installation of the test instrument and the machine under test is completed, the basic data initialization and barcode scanning tasks are directly performed. The overall software regards each test task as an event, and transmits messages between related software modules. Communication takes place and is scheduled by the operating system. During the test process, each module follows a similar process, the main branch is the operation of the instrument (including the sending of text commands and test data...

Abstract

This invention relates to a system for auto-testing wireless LAN RF index, belonging to auto-controlling technology field, which adopts WLAN test equipment as flat form, comprising frequency spectrograph E4445A, signal source E4438C, danamometer E4416A, signalyzerE8408A and programmable fader 11713A and so on, using IEEE488 bus and its communication protocol via software programming to actualize auto-test of WLAN RF unit. The software is composed of a basic driving block, a bar-code scanning block, a power-testing block, a waveform testing and analyzing block, a minimum sensitivity testing block, a throughput testing block and a database-generating block. The invention use present testing equipment to actualize the auto-testing of wireless LAN RF unit function, and judges the test and improves service efficiency of the system and productivity in batch.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to an automatic test system for wireless local area network (WLAN) radio frequency indicators. It is based on Agilent's WLAN test equipment as a platform, these test instruments include: spectrum analyzer: E4445A signal source: E4438C power meter: E4416A signal analyzer: E8408A programmable attenuator: 11713A, etc., using IEEE488 bus and its The communication protocol realizes the test automation of the WLAN radio frequency unit through software programming. Background technique [0002] Usually, in the production process of wireless LAN, for each test item, it is necessary to use the corresponding instrument to connect with the device under test, and then use the keys on the operation panel to conduct the test, and manually read the test results to make corresponding conclusions. Because RF test equipment is relatively expensive, and because test automation i...
