Very basic error, don't know his reason

Hello

I use your Express measure to calculate the amplitude and frequency of the signal to simulate for verification of the base.

Here if I connect the control of the frequency of the signal of the simulation, the vi correctly while when I disconnect the frequency of the signal to simulate, the measure of your Express does not have a correct reading for the Amplitude and frequecny. While the graph is displayed correctly.

Is this a bug or a mistake in the programming.

Pls help out.

Thank you

I did to change the number of samples to 400:

and then I get to the values that you used (8 Hz, 21 amp frq) this signal and correct estimates:
