• 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. 
  its pure eevblog!

• 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.)

• 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/.
