Hello,

you can lower your noise level about a factor 1.4 if you add both channels.

The signals in the sum is doubled, but the noise is only about 1,4.

Cool trick, I like it!
It is nice..
A bit more on the topic.


Thank you for the interesting article attached, food for thought.  Simple averaging can work near miracles, but the cross correlation techniques described sound like actual miracles!

Here is some more data on the LNA-10. Should work fine for your purposes.

Thanks. Mine is on the way. I chatted with the engineer Bill Lee on the phone for a while today. He figures for 100khz bandwidth I will be able to measure down to 0.4uV RMS. Impressive unit for the price. Not sure why anyone would need to spend $8000 on the Lacroy box. Dave should have mentioned this unit in his ripple and noise video. It's pretty much a no brainer to use something like this. The big advantage is the differential mode with 90db CMRR. Common mode noise will be way less than the signal.

5: Made in the Czech Republic in R&S's own quality controlled factory rather than a 3rd party Chinese factory like the Keysight

Are you sure that is made in Czech Republic? Does this referred to his label?

All our 1000/2000/3000/4000 scopes are made in the Czech Republic, about three hours from the design teams in Germany.
