6.4     Rotation examples with source tuning

QW-BHM allows joint modelling of load rotation and source tuning. The heat_rot_man.pro example can be transformed into heat_rot_tune.pro analogously heat_auto.pro as has been transformed into heat_pulse.pro and then heat_tune.pro in Sensitivity to the tuning and Syntax of tasker file:

- waveguide port is re-defined as one with reference plane,

- its excitation is changed to a pulse of spectrum 2.3÷2.6 GHz,

- S-differential postprocessing is activated in the band 2.4÷2.5 GHz.

In fact, a faster way is to convert heat_tune.pro into heat_rot_tune.pro by adding rotation details as shown in Fig. 6.4-1.
