ADXL1001 Noise Calculation

Hello,

 

I'm a student working with the ADXL1001 Accelerometer for vibration measurement (using LabView). I am trying to measure the noise of the sensor. As per my understanding so far, this is what I have done:

*Mounted the sensor

*Measured the output (under no input vibration conditions)

*and then measured the output of the sensor.

 

The standard deviation of the voltage output signal around the mean gives me the RMS noise of the sensor. I would also like to compare the noise calculated from the Power Spectral Density with this RMS noise. But I am not sure about how I can obtain the RMS voltage from the PSD graph. Could someone please explain me that?

 

The document that I used as a reference is this one: https://wiki.analog.com/_media/mems/reference_document_on_achieving_best_noise_performance_with_adxl1002.pdf 

 

P.S.: Feel free to correct me if I was wrong anywhere, I'd be happy to learn!

 

Thanks in advance
