Chapter Overview
In contrast to the fully general multiple source control approach (see Multiple Source Control (Option 007)) and the algorithm-specific NxN approach (see NxN Application), the mixer wizard and (guided) mixer setup approach help to setup common mixer measurements with a simplified, yet still accurate, calibration methodology. The prime objective of the guided mixer setup is to help configure the frequency plan of the measurement using easier to understand diagrams. The mixer wizard goes a step further and helps configure measurement channels to handle any of a suite of possible mixer measurements and to list the required calibration steps. Both of these tools are coupled with a mixer calibration menu system that enables both scalar and vector corrected measurements.
