TMS320F280049: SFRA: MATLAB script in control SUITE didn't seems to convert SFRA output to what I want

Part Number: TMS320F280049
Other Parts Discussed in Thread: SFRA, CONTROLSUITE

Hi expert,

I am investigating in SFRA and doing some test on "buck_F28004x" example. My purpose is to convert SFRA's RAW data to transfer function in MATLAB. Issue I met is what I get from MATLAB script provided in "C:\ti\controlSUITE_3_4_9\libs\app_libs\SFRA\v1_20_00_00\Scripts" is different from what is shown in SFRA. As shown below.

May I know what is the problem here?

Thanks

Sheldon
