The steps of the recommended procedure at the customer factory and in-field
operations are listed below. Reference to the relevant flow diagram in the Appendix
section has been provided for each step.
- Saving RF INIT calibration results at customer factory.
- The flow diagram for this
step is conceptually illustrated by Figure 7-1.
- Offsets measurement at customer factory
- Inter-channel imbalances
measurement concept is illustrated by Figure 7-2.
- TX phase shifter error
measurement concept is illustrated by Figure 7-3.
- Restoring customer factory calibration results in-field.
- The flow diagram for this
step is conceptually illustrated by Figure 7-4.
- Host based temperature drift effects mitigation in-field.
- Mitigation of
inter-channel imbalances is conceptually illustrated by Figure 7-5.
- Mitigation of TX phase
shifter error is conceptually illustrated by Figure 7-6.
Each of the above steps is elaborated with details in the following sections.
