This is the design of a test GUI developed with National Instruments LabWindows CVI 9.0 GUI development software. This application is for manufacturing functional test of secure wireless network devices. I also aided in design of hardware circuit to control RF switches to channel connections to devices in a test chassis. I coded software modules in C language to control Xyplex Terminal Server, Dell PoE switch and Anritsu USB RF power Sensor. This configuration was to sign on to 18 different wireless RF radios and configure them to operate as wireless networks. The test then proceeded to connect to each wireless device and measure the RF signal strength and message throughput. The main goal of this test was to verify that the units were functioning properly and that the internal RF antenna connections were good.
