spectrum graph

[Chelectro]

How can we make a graph of labview look like a spectrum graph. I'm trying to measure the Voltage Vs Frequency with Labview but I would like to have the same results as when I measure with spectra plus.

To make the graph look like that you can right click on the spectrum graph and select properties from the menu, there you can change the scaling of the x axis to be logarithmic and other display settings. To get the spectrum to display up to a frequency of 20k your sampling frequency will need to be at least 40k. You might want to also play around with the different windows, Hanning is usually used.

Thank you so much, I believe the software needs some adjustment to see the High and Low frequencies more intensive in gain. I will try to figure it out but

could I contact you if I have more question?

Thanks again.
