Sure it does.  Low level measurements are only one of the hundreds or thousands of use cases for a good oscilloscope.

It would be worth while finding out what is casing your noise though.  Then when you do need to make low level measurements you can disable/disconnect it.

My normal environment is quite noisy to,  in order to take the measurements I did today I had to turn quite a few things of around the house.

None at all. What you have now is fully capable for these tasks and better than most and offering 500uV/div sensitivity.

I don't think he's considering upgrading.  I think he means his Sgilent is the "expensive" scope.

It's all relative.  Compared to a Hantek or a Fnirsi it is or even to lower end Siglents and Rigols. It's 10 times the price of a DSO154 Pro!!
