6.2 Main Calibration Flow Diagram Using the CDB5484
The following flow diagram shows the implemented of gain calibration using the CDB5484U and a PC as the
controller. The MTE source is used to provide the source voltage and load current. Each step of the flow shows
the CDB5484 GUI screen capture of execution and reading results. The register writes and reads are all identi-
fied for easy compares to the GUI screen. The GUI is not promoted for production level calibration but does pro-
vide an excellent debugger for customer flow evaluation.
