Plot Frequency Response limited to ~24 KHz

I was plotting a simple 1st order LPF at ~2 KHz and noticed the filter's response was abruptly cut off around 24 KHz.  My modules are running at Fs = 192 KHz.  How do I get the full bandwidth response?

Hello,

Are you using the LPF that's part of the SecondOrderFilterSmoothed module? If you right click the module and choose 'View Properties', under the 'Variables' tab you can change the 'Max' value for the 'freq' variable. This will increase the range that gets plotted when you 'Plot Frequency Response'. 

 

If you're using a different module and the steps above don't work, let me know.

Thanks

-Axel
