There are also many guides from Agilent/Keysight and B&K Precision on line. Do you want to have modulation and different wave shapes (square, triangular, arbitrary as well as sine)? It is worth reading up about how these things work - an article I found most helpful was : I don't know if the link is working but Google the title. Apart from bandwidth you need to decide whether or not you're bothered by jitter, whether you want low phase noise at audio frequencies, if you will want more than one channel and whether you might want to play back long arbitrary waveforms or perhaps have short pulses spaced by large intervals (which can be problematic for some signal generators). ![]() To look at 50MHz square waves (say clocks) needs a scope that can show 3rd harmonic and perhaps 5th harmonic without too much attenuation so I (a bit extravagantly) went for a 350MHz scope but my signal generator is the Agillent one that goes to 30MHz including square waves. So I decided I wouldn't be doing GHz rf stuff but might want to run things up to around 50MHz at most.
