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.

Hello,

I would like to recreate your issue, but I am having trouble locating a "Spectral Measurement (picusb)" VI. Where did you find this file?

In LabVIEW 2012, the NI Example Finder has a similar example name found through: Analysis, Signal Processing and Mathematics»FFT and Frequency Analysis»Spectrum Measurements.vi .

The National Instruments examples do not have locked block diagrams, as we want our customers to learn from the code. Generally, you cannot modify a password protected VI. However, you might be able to use your example VI as a subVI and modify the example's outputs programmatically in the wrapper VI.
