Had one and sold it. Screen is too small and FFT suck. Megazoom is nice though.
If Sir wishes to look into the frequency domain, then Sir should really look at a Spectrum Analyser. We have them in all types: 20kg, 30kg, and so on, but my personal favourite is the Alabama 'StaysFast' at 110 lb - American of course, but still a very
substantial instrument.
If Sir finds the screens too small might I suggest that Sir visits my cousin at his optometry practice, where Sir will also find some nice heavy vintage tortoiseshell celluloid frames - my cousin can even match the year of manufacture to Sir's favourite 3
1/
2 digit bench DVM or AvoMeter. If Sir
is into Americana, I believe that he currently has some rather fine original 1960s RayBan spectacle frames in stock, as well as the ever popular sunglasses of the same brand for when Sir needs to preserve his sight's dark adaption for viewing particularly fast and dim CRT traces.
