Zoom FRF/FFT

Hello.  I am having trouble running the attached VI.  More specifically, the Real values of the FFT and FRF are not plotting to the graph.  Ideally, I would like to capture a signal at 50,000 samples/second for 1 second and output an FRF of the signal (or an input/output signal) between 0 and 500 Hz with the smallest frequency resolution as possible.  I have simulated two signals with these settings and set the zoom settings on the FFT and FRF to include frequencies between 0 and 500 Hz with a large amount of # of lines.  I'm stuck here, please help.

After installing the toolkit you should be able to explore the Zoom FRF examples which can be searched through LabVIEW. Type in "FRF" in the LV example finder for a list. Also, see the following similar post and page for helpful information.

By the way, your code runs just fine on my end and all the graphs are plotting.

Thank you for responding.  Could you please post a screenshot of the settings you used and more importantly, of the front pannel with the graphs plotted?

You are welcome, I didn't change any parameters, I simply ran your program.
