CPUOSM calibration
A SMARTer UOSM scalar vector mixer calibration using a calibration unit, a power
meter and a calibration mixer.
Same procedure as described in
on page 1623; just replace
VPUosm
by
CPUosm
.

Mixer measurement
The following example is a remote implementation of the tasks the
performs at the GUI.
The power meter and a four-port calibration unit has to be configured beforehand.
