--- Quote from: Fungus on July 15, 2024, 06:17:46 am ---That completely goes away after a week or so. (OKl, I left mine powered on for a week in a spare room so it was warm so YMMV but the smell definitely goes away) No idea why they chose that plastic. Is it still the same in new ones...? --- End quote --- In my case the smell was there, very intense (especially when the scope was turned on) after 6 month or so! I've kept it in the solar light on a balcony with 30 degrees or higher temperature. Also I kept it running in a free space for few days in a row without luck. So I've tried what I could to get rid of that but no luck at all. The trouble with the smell is there is no way to know about it in advance. Simply there are no specifications for it. And if does exist, nobody can guarantee it will gone after a while. Coming back to SDS824x HD, do you (or others) know if this scope has a similar smell (if you smell DHO804 you know what I mean by "similar smell")? Thank you. BR, Cristian |

--- Quote from: Martin72 on July 14, 2024, 10:10:15 pm --- Let's get back to your main concern, the measurement of "speed", the FPS. I still don't quite know what you mean by that, as you mentioned realtime spectrum analyzers as a comparison. --- End quote --- Hi Martin72, Forget about real time or however we call it. Let focus on what I want to find out by this post. Say you have a certain FFT settings (you name it). I want to know how long it will take to solve and display that FFT on both scopes (same settings), SDS824x HD and DHO804. I hope now it is much more clear what I need. Can you (or others) answer to this question please? If possible without arguments from theoretical point of view (no need for theme). Thank you. BR, Cristian |

--- Quote from: tautech on July 14, 2024, 10:00:18 pm --- There are many examples of FFT use here: https://www.eevblog.com/forum/testgear/sds800x-hd-review-demonstration-thread/ --- End quote --- Hello Tautech, Thank you for the answer. I know the above thread. I could not see a speed comparison (how long it takes to compute and display the results) for a given FFT settings between SDS824x HD and DHO804. If you find such post, please point me to it but please, if it is possible directly to the message, not the whole thread (with tens or hundreds of messages!) It could be useful. Thank you. BR, Cristian |

It seems like FFT is the primary goal here - perhaps the solution is to purchase the appropriate test gear ie an actual Spectrum Analyzer ? As others have pointed out, the FFT feature on entry level scopes is more of a math channel operation on the acquired signal. |

In fact I have pleased with its FFT speed (update speed on the screen) and I simply want to know if I can expect the same speed from SDS824x HD. That is all. Can you answer to this question please? You have the scope, that I want to buy it and I'm in stand by after this FFT clarification. Thanks for help. |
