Software Developer's Kit
The SDK document outlines the API specification for the G35DDC (Excalibur Ultra) series of WiNRADiO receivers, including the interfacing syntax and examples for C/C++ and C# programming languages.
The coherent mode SDK document describes the API that allows to use the device in coherent mode.
This makes it possible for a third-party software developer to gain complete control over the G35DDC receiver. This includes tuning the receiver, controlling the attenuator and gain, as well as reading the signal strength, gaining access to the digitally down-converted data stream and the demodulated signal.
