Hi,
I own a GW-Instek MDO 2072 and use it for HF and VHF projects. I use mostly the spectrum analyser option which runs to 500 Mhz. It also has a function generator which runs till 25 Mhz. It works quite well but the spectrum analyser is a extended FFT that is it looks like and works like a real spectrum analyser but uses FFT to generate the picture. For HF and VHF work (till 146 Mhz) it works good but you have first to use the scope to get a good signal and then put it to spectrum analyser. Some times when the signal is to strong you get wrong result in the spectrum analyser. Thats why I first check the signal in scope function. The one thing that is lacking is that the functiongenerator cannot function as tracking generator
. That would have been great, but I now use a nanovna for that.
So if you are on a low budget and need a scope / spectrumanalyser this is a bargain. If you have 2k to spare I would consider two seperate instruments. But I have lots of fun with this scope.
