ni5660 read average power spectrum

[StoneAntony]

Hi,

I'm usig the ni5660 Vis for frequency domain meaasurement, I create a simply VI to view immediatly some signal in freq. but I don't know how to perform a peakhold (maxhold) fuction. I attached the file so maybe it more simply to resolve the problem.

Thanks.

ok, I resolved whit the attached .vi file, I think it's correct...but if there are other solution, tell me. 

Thanks.
