"Spectral measurement|" (picusb.vi)

[nalinda]

In the Example "Spectral measurement|" (picusb.vi) the VI send the data to the Device and Show the reply from the Device. So when device does not respond, once again shows the Ealier respond. How to avoid this.It shold not show any responce if Device does not respond. How to make this change in VI.(I cannot access the block diagram as it is password protected.) please advice.

Trust me, you are not going to like this: Get the password, or write a routine of your own.

The good news though is that if picusb.vi simply reads an analog input and then performs a spectral analysis of the aquired data, it might not be too hard.
