TMS320F28034: SFRA related variable

Part Number: TMS320F28034
Other Parts Discussed in Thread: SFRA

Hi,

my customer tested SFRA without GUI according to the app note below:

part 7: Using SFRA Without SFRA GUI Integration

//------- SFRA Related Variables --------
float plantMagVect[SFRA_FREQ_LENGTH];
float plantPhaseVect[SFRA_FREQ_LENGTH];
float olMagVect[SFRA_FREQ_LENGTH];
float olPhaseVect[SFRA_FREQ_LENGTH];
float freqVect[SFRA_FREQ_LENGTH];

They read out the variables above, freqVect is good, but for MagVect, PhaseVect, the number is very big (several thousands).

So they wonder if the number is correct,

If it's correct, do we have an equation to convert MagVect number to the real Magnitude(db) number shown below?

do we have an equation to convert PhaseVect number to real Phase(deg) number shown below?
