I am working on DAC bench automation.I am sending a digital signal at some sampling frequency to DAC(Digital to analog) board.
The output from the DAC board is connected to Spectrum Analyzer(Agilent E4440A).
Using LabVIEW driver I am able to get the Frequency domain signal in my Graph.
I wanted to calculate the THD,THD+N,SFDR,Harmonics and SNR.Please anybody suggest how i can get these values.I am having below information:-
1. Sampling Frequency
2. The amplitude of the received signal is in dBm and base (X-Axis) is in frequency.
3. Fundamental Frequency.
4. Start Frequency and Stop Frequency.
5. There is the attached sampled data and snapshot of the frequency domain graph.
