Simulink question about generating 14 bits digital codes from sine input

[yen]

I have a question.
I have a sine input and I want to generate 14 bits digital codes.
How do I control that 14 bits digital codes have 500 or 100 count.
Thank you.

My input is a sine wave.
It is an analog signal.I want to transfer it to a digital signal.
My digital signal is 14 bits.
How many datum do it generate?How do I control.
Maybe I just 500.but it generate 1000.

Re: simulink question

I advise to debug model on small number bit.
For example, I have made your model on 3 bits.
Look the appendix.

I measure SFDR.I do FFt (1024 point) and I use hanning(1024) window.
If I want to measure SFDR, which window is suit for it?
I have a question.I have a picture.Which one is my SFDR.
why? Thank you.

Dear gevy,
I can't open this file. There are some warnings during opening a file.
And I can't see any picture.Thank you very much.
