RIGOL DHO804 - can the FFT reach 625 MHz?

[@VladyslavDatsii]

We are looking forward to more. Also, if there is an opportunity to do a similar test on the SDS802X/804X, that would be great.

Very capable device. Thank you!

No technician, but litle ham-radio background:I very much appreciate those short clips of info in English! Great!

Please, make more English videos.

Thank you so much for doing this video. I just received my Dho924s. This test is epic. Now we know the DHO800/900 is so capable of handling higher frequencies than it was labeled. By the way, for 433Mhz LoRa transmission, can we detect frequency hopping/jumping using FFT in this oscilloscope? Such as some basic analysis of hopping counts and timing? Thank you so much🎉 Good job!

I'm happy you liked it! That's a great question about the hopping. I believe it will be able to do it just fine in 433 MHz. I do not have a LoRa module that is enabled in region 4 (433MHz), but I have one that operates in region 1 (915MHz). So I could use a mixer to downconvert it to 433 MHz to demonstrate the hopping.

@@LiraLab that’s a nice approach for testing Lora. Your videos are very nice!

[@Upper_Room_Studios]

Yes! Please! More videos in English! I'm in the market for a scope and I heard you can hack these and the 900 and 5000 models. I cannot figure it our from the THOUSANDS of posts on EEV blog. English vids on that would be AWESOME!

[@TheRealHarrypm]

It can be hacked upto the hardware and firmware level of the DHO925S, upto 450mhz bandwidth also.

Merci pour cette vidéo très intéressante

[@LiraLab]

Merci Frank! La série DHO a la meilleure FFT des oscilloscopes d'entrée. Le traitement numérique est très rapide!

[@keen2461]

Great video. Please keep making videos in english. You'll have a much broader audience.

[@aviationodyssey1892]

Great stuff! Please make more english videos:)

Yes mate, the tech world speaks English. No abacaxi here, just pineapples....

[@LiraLab]

True! Still, cannot ignore 200+ millions that speak portuguese in my country.

[@LawpickingLocksmith]

@@LiraLab If they speak the Brazillian accent who knows. Perhaps second used tech language has become Mandarin. Dying tech nations include Germany, Japan, Italy and also Australia. The Dutch are hanging in!

[@LiraLab]

@@LawpickingLocksmith btw, I'm Brazilian and I live in Brazil.

[@LawpickingLocksmith]

@@LiraLab Good to see at least another country making good planes. I grew up in central Europe and am impressed by Portuguese youtubers like general knowledge.

@@LawpickingLocksmith I lived in France for a year during my undergraduate. I was able to travel around Europe. Amazing continent!
