I don't understand, it should work well:

Link in first post seems to work OK for me..
In real terms the noise floor shown IMHO is exceptionally low, wondering how that was accomplished.
This is essentially an advertisement for what is an interesting product, nonetheless it belongs in the commercial forums. Hence its move to vendors bazaar.
Sorry for having chosen the wrong category.

The efforts where done mainly on the analog front end amplifier, multiple galvanic isolation to get the same result even when the equipment under test is connected to earth, in the ground/earth routing and in the power supply noise.
Yes it has become a commercial product, but for DIYers it can be an alternative to expensive high end audio analysers.
For DIYers high level measurements can be done by a sound card but very low noise measurement can't be done properly by a conventional sound card.
