Hi @gundanfans,

Actually, there are 2 NCOs. One is a “normal” which is controlled from “NCO” group. Another is a TSG NCO. It produces sine/cosine waves from 4 or 8 points. So, I would suggest to make this test:

1. Check **all** the check boxes in “Bypass” group;
2. Select “Test signal” in “Input source” group;
3. Select “NCO” in “TSGMODE” group.

What is the result?

And few more notes:

1. You can not set HBD/HBI to bypass. It should be 2^1. Otherwise MCLK frequency is not correct. This is very important!
2. Keep “Direction controls” from “LimeLight & PAD” -\> “Sample position & Clock” sub-tab default.
