I was just wondering if possible a noise source could be produced from the Cal output
to connect through a dut to look at its spectrum? - even if a bit rough, just to get an idea

Colin, its an interesting idea. To be investigated in case a substantial HW update is planned, which is not the case at the moment.
Space will be a problem, also power and cost.

But then, noise sources are easy to build and used externally or bought cheap on the internet. Why bogging down the TinySA with it?

If they are so easy to build, I would think it would not be a burden, and everything would be self-contained...

Easy to build if you have:
- space
- power
- money
May I suggest you open your tinySA and try to find space for the 3 amplifiers stages required to get some dynamic range?.
And try to find a component configuration that is stable, even with the huge gain of the cascaded amplifiers.
