FFT Reference Curve  

Application: Evaluation according to IEC61000-2-2, -3-3, IEEE519, etc. 

For 

Harmonic FFT analysis it’s possible to add a reference curve to the visualization screen. 

When selecting the quantities (1), you can add the desired reference curve at “Limits” (2). 

 

 

The limits are shown as circles in the visualization: 

 

For different graphs, different limits can be selected. 

The parameters can 

be shown in different quantiles (95%, 99%, 100% … definable) at the 

same time. 

Key Feature:

 IEEE519 requires different quantile calculations
