[QUOTE="vma, post: 993361, member: 256592"] Hi, The best is you take a look at this video: [MEDIA=youtube]4edLLw_7NRg[/MEDIA] If you use 1000 samples, it takes around 4 seconds for the whole span (no matter what frequency range) to refresh. Taking 500 samples takes about 2 seconds. Taking 250 samples takes about 1 second. Taking 100 samples takes less than 0.5 seconds. You cannot consider it "realtime" with more than 100 samples selected, but even with 500 samples it is pretty OK. For you to get an idea: with 500 samples selected, it is faster than the spectrum of a Kathrein MSK33 and just slightly slower than a KWS Varos 109 (while showing the spectrum at a higher resolution). Definitely useable! Regards, vma [/QUOTE]
