Change bandwidth on SVFA PSD VI

[martym]

I am using the S&V PSD VI to process 3 analog signals which are sampled at 15 kHz.  By default, the output of this VI is a PSD with a bandwidth of 0.1 Hz.  In order, to easily compare the data to some legacy data, I would like to have the data in ~15 Hz Bandwidth.  Is there a quick modification to the PSD VI I can do to change the bandwidth it outputs?  

Thanks,  Marty

The Power Spectrum Density frequency resolution is directly tied to the sampling rate and number of samples settings of your acquisition.  If you decrease the number of samples, this will in return lower the frequency resolution, but there is no direct way to specify this in the VI, it is just a result of the other settings.  Please navigate in LabVIEW to Help»Find Examples»Toolkits and Modules»Sound and Vibration»Analyzing and Processing Signals»Frequency (FFT) Measurements»SVXMPL_Baseband FFT (Simulated).vi and look at the result of changing these values in your simulated signal controls on the front panel.  You will see the result in Power Spectral Density.  Does this help?

Best,
