Traditional VNAs introduce latency between the VNA and ATE system’s control PC, resulting in an increase of failure points. USB VNAs deliver the same level of accuracy and performance as traditional instruments, while reducing space utilization, points of failure, and latency and complexity within ATE systems. The same PC that is used for an ATE system’s control and data processing and analysis, can be used for running and automating the VNA software application. Automation scripts can be developed in various programming languages, including MATLAB, Python, C++, Visual Basic (Excel), LabVIEW, and many others. Automation is available via COM/DCOM (ActiveX) or TCP socket server.
