The Microsoft .NET-based application programming interface (API) is provided to enable systematic and efficient configuration of complex WLAN 802.11a/b/g/j/p/n waveforms. The API allows programmatic setting of signal parameters by importing custom data sets or using programming loops and mathematical functions rather than manually entering data in the Signal Studio graphical user interface. The entire signal configuration and playback process can be automated easily in your own programming environment using the API.
