PC-compatible software with a graphical user interface (STSW-RFSOL003) allows the user to write and read all device registers. It can be downloaded from www.st.com. This gives direct control of circuit functions such as: operating frequency, reference frequency, input mode, charge pump current and low-power modes.
The user-oriented GUI aids understanding of the performance, features and characteristics of the STuW81300 device under test in a laboratory environment. The GUI instantly shows descriptions of its controls and indicators when the user hovers the mouse cursor over them.
