what's the best way to generate the spectral density plot eg dBuV/200Hz?

[steveADI]

There are great vis for PSD but is there an easy way to produce a spectral density plot with units dBuV/200Hz?

Hey steveMAX,

If you have the hardware which can acquire these voltages then it should be too difficult. You could use the Spectral Measurements Express VI to produce the data. This will automatically give you the output in dB. You may then need to resize the axis on the graph indicator you create so that you can view the correct data and label the axis appropriately.

Yes,

It was really just a metter of setting the up the resolution bandwidth of the Digister to match the spec.  It's all up and running now including limit Mask on the Mag/Log plot. 

Thanks for your advise.

Steve
