« Last post by Mechatrommer on Today at 08:30:56 am »Somebody just added a full screen mode to the Rigol...charming indeed but... the hidden complication is "not signed" app meaning no access to system file, cannot do screen capture. thats why be careful making post like this in beginner section. i know there's post about deactivating signing but i dont want to dig deeper until they finalize it. its still in R&D stage.
What was the topic again?discussion about nyquist, that lead to proper Sinc reconstruction reveals siglent DHO800X can do it properly unlike Rigol, this can also can help user make decision whether this is important or not. this discussion can also make newbie aware of some technical and theory informations. for me Sinc reconstruction is important when signals contains spectral near Sr / 2, let alone if more than that.
Question for a friend...
Since we are so far off topic, I guess it's okay for me to ask an incidental question. While all this conversation is quite interesting and instructive, I'm curious how many people actually use or need bandwidth or sampling beyond 100 MHz and 312.5 S/s?you never know what lie ahead of you. not so long ago, i deal with opamp circuit that experience oscillation beyond nyquist limit, granted BW limited siglent may suppressed this signal, but with rigol, i saw some nasty oscillation, but with betterer Sinc reconstruction, it may help distinguish some of signal near nyquist limit. if you can limit yourself to arduino circuit, you may not be aware of this and you are safe with rigol. but if you dont have enough belt color, unaware probing 250MHz spectral at 312.5MSps may bite you. ymmv.
