Spectral histogram of adc output

Solved!
Go to solution

G'day all

I have a LabVIEW task that I'm confident would have been dealt with before (many times). However, not for the life of me can I find a documented solution. It involves the display of a spectrum of channel hits from an ADC on a histogram (no, not the statistical flavour - the science spectral version).

I have a loop from the 8k ADC DAQ front end that (for the sake of this example) gives me the amplitude of an incoming pulse (a value between 0 and 8191). As part of that loop I'd like a real time 'live' spectrum of the accumulative number of hits per ADC channel.

I can think of ways using a 8k array and incrementing the bins manually but how to get the array data persistent in the loop... and actually display it.

If I have to invent my own wheel to solve this then that's OK but I'm sure like most of my coding brethren, I'd prefer to use somebody else's Smiley Wink

Cheers
Steve

Look at this example of a Histogram. Is that similar to what you need?

Thanks Broken. A round enough "wheel" to get me where I wanted.

 

Much appreciated
