Power Spectrum vi

[Luca Notini]

Hi,

Can anaybody tell me the maximum size of an array that can be accepted by
the Power Spectrum vi in the signal processing toolset?

I find that it does not produce an output if an array size of over 5 million
elemnts is used, however it produces the required output when the an input
array of 4 million elemnts is used.

Additionally, when an array of 5 million element and over is used as the
input:

1. No error message is produced.

2. This occurs even when averaging is activated.

Thanks,

Luca

I am not sure which VI you were using exactly. Is Power Spectrum.vi on the palette Function>>Analyze>>SIgnal Processing>>Frequency Domain? I have tried this VI and do not have the problem you mentioned.

Would you attach some testing VIs?
