DAQmx read connect Spectrum Measurement



I have read the national instrument video on youtube which shows the measurement of power spectrum of an analog input:


I tried to build a similar program, only using DAQmx to make it. I tried to connect DAQmx Read to Spectrum Measurement, but I couldn't get a real time display of the Spectrum. 


Attached is my VI. Could somebody give me an adivce on this??

Hi MatthewTang,


In the link below you will find a community example that demonstrates how to perform a measurement of power spectrum of an analog input using the DAQmx API. Please take a look at it and let me know if it helps.


Warm Regards,
