Hi,
I have some probleme with the vi FRF which computes Frequency Response. In the cluster "spectrum info", the channel name is not modified when the vi FRF is in a loop. It seems that this problem is when the polymorphic selection of the vi is defined on "1 stimulus, 1 response.
The attached vi shows my problem for a better understanding of the "bug".
The channelname (and maybe other properties of the spectrum) is not modified. I would like to store the result of the FRF vi in a TDMS file with the polymorphic VI "Write in TDMS" available in the toolkit Sound&Vibration. The Spectra should be saved with all the properties and the channelname should change....
Anybody has an idee to correct this problem ? Maybe I do not use the Frequency Response as it should be, but it seems that there is a bug in the vi.
Thanks for your help.
Mathieu

Hi,
I found what was wrong in my code.
In order to have the correct "spectrum info", I have to put the input "restart averaging" on the True value on the Frequency Response vi.
