I want split wave form.

[yeers]

currently, I'm using alazartech company SDK
it makes A+B sin waveform by function generator and generate FFT 
but I want Split A and B wave and display A and B signals separately

I used below 
but these didn't work

1. signal selector

 - it did not show signal2 and signal 1 is A+B wave form.
2 array index

-  just display A+B two wave from
3. SDK copy and paste

- last setting make wave form, if select A lastly wherever, display A
4. Array Subset

- just display A+B two wave from

5. split signal

- just display A+B two wave from

my english is short, It's my apologize.

You show a truncated code picture and nothing is labeled A or B.  You need to be much more specific.

here is full code PDF

PDF is no better than an image, in terms of LabVIEW, sharing the VIs is the best.

[yeers]

here is the vi file

but you should be in error.

because you don't have SDK file

but If you can analyze it, I am wiling to help.

We still don't know what A and B is. Are you talking about the blue wire forming the Y of the waveform? How does the data look like? Can you wire an indicator there, run the program until it displays the data, stop the VI and turn the indicator into a constant and attach the VI again so we have something to look at?

It seems you are trying to find two frequencies with a hairball of code. Once we know how the signal looks like, it will become more clear. Does the signal contain two major frequencies? How much noise is there? For Frequency 2, you probably need to add the index of the first frequency.

[yeers]

Yes, I'm talking about the blue wire forming the Y of the waveform,

and

below refer to the A, AB, and B signal image

and currently,the A signal is not working. but it is device problem. don't care about that

[altenbach]

So your waveform contains two equal parts, both with an offset of about 37000. The first looks like noise and the second with a large amplitude high frequency that we cannot see because it just looks like a blue filled square. No way to tell more unless you actually attach some real data.

I would think you should split first, then fft each half separately.

[yeers]

What kind of real data?

I can't understand.

I can attach file as possible as I can.

if you ask me for specific order. I will make it.
