DAQmx read connect Spectrum Measurement

[MatthewTang]

Hi, 

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??

Best,

Matthew

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.
