SINAD analysis VI

Hi,

I 'm trying to use SINAD analyser. I 'm looking for rms value of noise (integrate noise over fs/2)+rms values of all harmonics. But I don't want to include DC. In the SINAD VI, if I use exported signals and use residue signals in export signal option, would the value coming out be excluding the DC component or its DC +harmonics +noise?

The output of the residue should be RSS voltage addition of integrated  noise +rms addition of harmonics. Can I get that? I can add individual harmonics but I can' t get the integrated noise over the bandwidth (fs/2).

 

I hope I'm able to drive my question.

Any inputs appreciated.

Thanks inadvance

Read the "Using the SINAD Analyzer VI" section in this link. It is clear that the output is except the  DC component.

The "SINAD (dB)" and "THD plus noise" outputs are calculated with the DC value excluded. The exported signal spectra, however, do not exclude the DC component. I believe that this is causing some confusion when referring to the "outputs" of the vi.
