Spectrum Analyzer sample rate.

13 views (last 30 days)
How do I change the sample rate of the spectrum analyser in a circuit? I cannot do this in either simulink or simscape. I keep getting an error that says it cannot open because the sample rate cannot be either continuous or zero.

Hello Paul,
Please check the signal type of inport signal connected to Spectrum Analyzer Block. It must be a discrete signal. It is also written in the documentation.(see below)
If the signal is continuous and you want to change it to a discrete signal, please use Rate Transition block.(see below)
I hope this will help.

Hi Paul,
When you right click on the Spectrum Analyzer block and click on the "Properties" option, the following window will pop up:
After you click on the highlighted link, it leads you to the Spectrum Analyzer1 window which looks like the following:
On the top-left corner you can select Spectrum Settings(highlighted using Yellow) and then you can set the sample rate using the option as shown on the right (highlighted using Red).
Hope this helps!

This did not work. The sample rate box just shows Inherited and I cannot change it.
thanks though.
