Help with Siglent SDG1025 Ouputting "Pink Noise"

[Tacheon]

Greetings EEV'ers and Dave, thanks for all you do down unda.

I just purchased a Siglent SDG1025 Func. Gen, and I like everything except the noise feature. I expected it to be "White" noise, and was simply going to run it through a passive filter to convert it to pink noise for audio testing. Unfortunately, I made the wrong assumption, and it turns out the unit outputs Gaussian noise, which doesn't work for me. I contacted the company, and they did attempt to provide me a spread sheet in .CSV format which was supposed to simulate pink noise. I loaded the file, but it seems that there is a sawtooth signal associated with it. I think it just might be number crunching it over and over, at the start point and I am seeing the math, but not sure. I wanted to use easywave software, and try to have the unit crunch an equation from the noise signal that the software provides, but I am not sure how to do that. Might anyone have an idea or work around on how to get this unit to output Pink Noise?

Here is a link for the equation: http://en.wikipedia.org/wiki/Pink_noise

Attached is a .CSV file from Siglent

Help?

Hi Tacheon,

I'm just a Newbie so I don't know if you still need an answer to this question.
Anyway, my attempt at a solution was to change the CSV file using a fill down column formula like this;
=20*RAND()-10
I've attached the modified CSV

"I wanted white noise, but I got Gaussian noise" makes no sense. The Gaussian noise will almost certainly be white. If you don't want Gaussian statistics, what are you looking for?

Doh! (as I slap my forehead). White noise has a flat spectral density, but in pink noise the frequency spectrum falls off as 1/frequency. I forgot to include that factor in my previous response, sorry. In fact the way I attacked the problem was a complete failure (sorry about that too).
The maths is too hard for me but interesting; See here http://www.firstpr.com.au/dsp/pink-noise/
