repeat swept sine

[MasterOfDesaster]

I 'm performing a swept sine task in a test sequenzer.
The swept sine measurement is realized with the given
example "SVXMPL_GettingStarted with Swept sine".
The first time i call that vi it works
correct. In all subsequent cycles the swept sine sub vi generates no data about the magnitute (NaN). I would be glad if sombody could help me with that problem.
If i use that example vi in a while loop i do have the
same problem.
I would be glad iv somebody could help me.

If some VI works correctly first time and then when you run again not then is a problem with initialisation of you input/output parameters ... the values are kept until you close LabView ... or release explicitly the memory ...

Hey Oriana,

thanks for your suggestion. Unfortunately the vi I use is an example from sound and vibration toolset. I just putted it in a test sequencer. For debugging I changed all inputs to constants and integrated it in a while loop. Nevertheless the error occurs.
