Mouse just plug in via USB???

Which one is better ?

The RIgol not autoscaling after the Bode plot is a real let down. Keysight EDUX1052g does the autoscale after bode. Is there an option to rescale after the run?

omg

handheld camera are you kidding me

What is the fan noise like on this DHO924s?

I just got my 924S and so far so good. When you're used to trying to get a Hantek MSO just to trigger reliably, this scope makes me wonder what I've been wasting my time doing for the last few years LOL. Anyway have you tried/managed to upgrade the firmware at all. Mines on 1.02 and there is (according to eevblog) a 1.03. But I can't for the life of me get it to download. I've tried all the suggested links and I just get an XML error. On the official Rigol website, following the support links they only show V1.02. You seem to have to have the direct link to get to the V1.03. And ye I'm logged into my Rigol account. Not too worried because I don't seem to be bothered by any of the reported bugs, but still... Nice video series BTW 🙂

So can we expect some big review of these two models with tests?

Hi Steve, I've read a lot of comments about bugs in the firmware of the DHO800/900 series. Would you still recommend buying this oscilloscope for fairly frequent use to generate bode diagrams and use mostly in linear electronics? If not, do you have any suggestions at a price of less than $1250 CAD? We look forward to hearing from you.

Rigol all the way!

How about FAN noise in the 924 which have been present in earlyer model?

Hi Steven, thanks for the comprehensive series comparing the older DS1000z series vs the DHO900. I had the DHO900 previously and returned it after a while. Too many bugs, odd options and no DOT mode. The DS1000z series is even nowadays quite amazing and very useful. Even though I have a Siglent DSO I will get the DS1000z because of the nice history mode. Do not count on that Rigol will implement on the DHO900. Maybe in 5 or 6 years ;-).... DHO800 & DHO900 series only there for 12bit ADC. The rest is very questionable. Average users will perhaps like convenience like touchscreen, mouse operation etc.... But for a 12bit the Siglent SD800X HD is a way better DSO versus the DHO900 from Rigol. Thanks for your effort here. Kind regards...

Nice video. I'm a beginner, and just got into electronics. I purchased the "DHO 804" model. It would be nice if you could record a beginner tutorial on how to use the scope properly and what should I do with the information I get from it.

se fosse un problema di sovraccarico del sistema Android si potrebbe migliorare , con un algoritmo più efficiente . Purtroppo penso che sia un difetto del front-end analogico e resterà per sempre

Steve, how did you enable the cursors in FFT view? On my DHO804 it doesn't work.

Steve, just increase the memory depth up to 25MPts or more in Wave view and you'll see the dancing there, too. I clearly can see the "smearing" in Wave view.

Why no comparison with Rigol DHO814 which is its more direct competition at its price point?

Are these changes persistent after reboot?

Hi, is it possible to have it output a signal, connect that to a breadboard then also connect a channel to the breadboard to measure the signal. So you can use it as a signal generator and oscilloscope at the same time. E.g I don't need another oscilloscope to monitor the signal?

I recently purchased the DHO924s and found that the RS232 serial decode does not work if I set the probe to x10 and scope to x10. I could not find a decode threshold setting that would make it decode the RS232 data. If I have the scope set to x1 but the probe is still at x10 it is able to decode the RS232 if the decode threshold is about the same as channel 1 trigger level. I think it must be a bug in Rigol's firmware for this scope. My scope has the latest firmware v1.02 released early 2024.

Not always You need to isolate generator. But always You will have ground loop, which can make bad measurements on higher frequencies (like 1 MHz or more).

Hello friend, can you clear my doubts, with this compatible probe I can read TTL signals below 1.5v or 1V Thank you for your attention

which is better one?

that’s really cool

I guess filtering 1,2,3 bytes in i2c triggering is okay for the cpu. filtering 4,5 bytes binaries can be a very troublesome task for the cpu. But maybe it's a bug not a cpu thing.

1.30 - 1.32V is the dead trigger voltage zone for this Ebay logic probe. Thanks for sharing! Very useful! And you found a "bug". Hopefully they can fix it. Cheers!

Dumb question - which scope is quieter?

Hello. I recently got the same oscilloscope and your videos are very instructive. Rigol recommends using a transformer to match the impedance between the generator output and the circuit to which the signal is sent. However, unless I'm mistaken, the datasheet gives no information on the electrical characteristics of the transformer to be used. I used the output of the generator without a transformer on a 455kHz ceramic rejection filter. Its input impedance is quite high, around 100kohms, and the Bode diagram was produced without any problems. I understand the use of the transformer in the typical switching power supply diagram provided by Rigol, but if a transformer is required to protect the generator output, Rigol should give the electrical characteristics of this output. Is it that fragile, and if so, what is it made of? Unless the electrical characteristics of this output are available, but I haven't found them. Thank you for your videos and best wishes for the future.

I am looking forward for this comparison. Especially the power analysis of the siglen. J'attend la comparaison des deux scope. Surtout la fonction de power analysis de siglent.

Very interesting! Could you pls. do me a *big* favour and check if SPi Decoding works with your DHO924S *together with the LA* ? I'm asking because I own a DH0924S in conjunction with an original LA Modul from RIGOL but I wasn't successful to use the SPI Decoder by just using the LA's channels alone. Everything works fine as long I feed MOSI, SCLK and CS into the *analog* channels. But If I feed in these Signals into 3 LA Channels and assign them within the SPI Protocol Decoder the Decoder will not show any decoded values as I successful got when i used the Analog Channels (with appropraite Threshold values). The LA Traces show the SPi Signals just fine but the SPI Protocol decoder will ignore the signals from the LA. May you pls. give this a try with your Setup? I'm very curious if this is a FW Bug which I suspect. Thank you very much in advance! BR - Peter from Munich, Germany - ;)

Are you happy with the Siglent?

Nice, i've been waiting for the siglent to release that scope and see some reviews against the rigol, there are quite a few things that i didn't like in the new rigol.

Hi How did you call up the clock and date on the DHO924S?

Very nice!

Great presentation. Continue your great work.

How have you managed to have the time and date displayed in the bottom right corner, I don’t think my 914s does that!

It will be useful to mention the firmware version as well.

LA part of DHO900 seems to be... quite bad honestly. Especially considering the price of the probe. Hardware may be solid but UI is buggy and somewhat cumbersome. Support by external software would be amazing (sigrok?) but there is none so far. Please test the decoders. I wasn't impressed when I tried them on analog channels (DHO800) but maybe I did not put enough effort into this.

Merci Steve pour la démo 👍

Interesting... Merci pour la vidéo and happy to follow your channel... ✌

Make Video On SPI Communication with Oscilloscope Setting...

Looks like a very good scope, but the only 2 things I feel is missing is a switch to 50 ohm termination on the inputs, and a functionsgenerator to 60- 80 Mhz - then I would smash my piggy bank immediately

Where to find this file? could you share link pls?

Where is the data coming from? You didn't say anything about what is connected to the scopes at all.

Just use a a separate data analyzer , a scope ia a scope not a data analyzer , you can not do much with the results

I use a separate procol analyzer much better solution

The Rigol DHO924s seems like a very nice oscilloscope? The interesting spec is 12 bit vertical. Are you pleased with this oscilloscope? Thank you.

useful and practical information
