The LO Configuration tool is available from the Tools menu, but only if privileged operations are enabled. It is an interface to the algorithms used by the OT to generate tuning solutions. At its most basic, the centre frequencies of up to four basebands can be entered and a tuning solution (LO1 and LO2 frequencies) requested. Figure 7.6 demonstrates the use of this tool to derive a tuning solution for three basebands at Band 9.
