We have the ships.

We have the weapons.

We need soldiers.

Soldiers like Lieutenant Dave Jones.

I think it would be appropriate considering the vast rigol 1052e support. It would be nice for dave to get down to his 1052e roots. I've started to feel a bit disconnected from the blog because of all the high end gear that is being reviewed.

You covered the 100mhz mod, so why not this? Especially now that you have a real spectrum analyzer.  8) 8) 8) 8) 8) 8) 8) 8) 8)

You can use a DSO as a spectrum analyzer, but you'll have to spend a whole lot to get a bandwidth equivalent to that of even the most basic spectrum analyzer. Good spectrum analyzers also have very good dynamic range.

What might be interesting would be to make a spectrum analyzer by connecting something like a modified satellite or cable TV tuner to a low cost scope and having a PC control the whole thing. (Add further stages of downconversion and you might be able to use a sound card, although it would take longer to perform a sweep.)
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

That would be an interesting comparison, its most to see how good dexter's software is.

Since eevblog may have a Rigol SA still handy, it could be worth a look:

Should this be moved to the suggestions section? It might be more likely to get on Dave's radar there.

Using cable TV tuners to make a spectrum analyzer was done quite a few years ago, NiHaoMike. The project is called the Poor Man's Spectrum Analyzer. The website is http://www.science-workshop.com/.
