content: I am a beginner in electronics and wanted to buy an oscilloscope. A 4 Channel DHO800 In my country costs roughly $580 usd. Where as a Ds1054-Z costs roughly $480usd. My budget is tight and contemplating which one to get. I do not know if ill be actually making use of the 12bit on dho800. I will hopefully reach a stage where i would be analyzing spi, i2c signals within 4 months. So evidently ill be moving at a fast pace and im skeptical if the 12bit is needed if i continue learning at this pace. My learning would strictly be restricted to digital, analog electronics, audio electronics. My end project would be to "hack" a ps5.Reasons I want the 1054 over the Dho800:1) Build Quality2) ReputationIf i want a dho800 for around 480$usd then it would have only two channels.Please help im really confused. An oscilloscope is a big investment for me. Please help me choose one over the other.

content: Please note typo. DHO804 in the title and not DHO800. DHO800 only for the last second sentence

content: Hi,I own the DHO804 and have the DS1054Z here from work for comparison.I´ve tested the DHO804 over 6 weeks and I must say, it would be worth to spend a bit more for it.It´s in nearly every case above the DS1054Z, decodes from the memory, way better screen....If you want to know something else, let me know.

The DS1054Z is an antique by comparison.eg. You mention serial decoding: The serial decoding on the DHO800 is a whole other level compared to the DS1054Z.Quote from: mkosett on November 27, 2023, 07:42:12 pmSame build quality. Same reputation.(I've owned both)

content: As im a beginner, i am scared that i can destroy the oscilloscope by bad connections/overvoltage etc. Is the 1054Z more resistant to getting destroyed than the dho800? And what about repairability, which is better self repairable than the other?

content: Quote from: mkosett on November 28, 2023, 05:03:20 amRemember: Always use probes in 10x mode. This divides the voltage by 10inside the probe.ie. With 10V input, only 1V will arrive at the 'scope.Quote from: mkosett on November 28, 2023, 05:03:20 amBoth are 300V rated. With 10x probe it takes 3000V to overload it.Quote from: mkosett on November 28, 2023, 05:03:20 amNeither are very repairable.The thing most likely to fail is the power supply. The DHO800 uses an external USB-C for power supply and can run off suitable phone chargers, etc. You can even use a USB powerbank to power it from battery.

content: Quote from: Martin72 on November 28, 2023, 11:38:22 amThe probes supplied with the DHO800 are clearly labelled:Saying 10x300=3000 is a mathematical fact. Nobody was asking about measuring 3000V, nobody was saying it was OK to do so.

content: Quote from: Fungus on November 28, 2023, 03:32:20 pmno! its saying the probe is only designed for 300V at probe tip at 1/10X setting... that means only 30V will reach dso... no such thing as 3000V is implied over there.

content: Quote from: Fungus on November 28, 2023, 08:07:25 amThis statement is totally irresponsible, especially when responding to someone that identifies as a beginner, and likely and open door for liability!! The PV3150 probes provided with the DHO824 are rated Cat II for 300V at 10X, and 150V at 1X as are most generic scope probes!!Only specialized scope probes rated for higher voltage should be applied beyond the 150/300V ratings, this is quite dangerous lethal territory!!Hope folks recognize this, and also recognize the source of such dangerous misinformation

content: he (that statement) is correct though if using specialized probe rated for 3KV at 1/10X... but not for your normal joe rigol probe.

content: Since I have been looking at 800 up through 2000 series, the DHO804 is bare minimum to buy, you can then "upgrade" it to the 814. Also limited to 100MHz spec, -3db should be somewhere near 180MHz. Albeit single shared ADC.As for mixed signal, sorry just have to comment on it, the SDS1104X-E is on sale now and comes with digi bundle SDS1000X-E-FG and SDS1000X-E-16LA for $475. This SDS can also be "upgraded" to 200MHz. Dual ADC.Each has their own learning curve and are different, but nothing drastic.

content: Quote from: Randy222 on November 28, 2023, 05:33:14 pmI haven't used any of the scopes of this thread, but I think it's relevant to point out that, as a hobbyist, the licenses for the AWG and LA are pretty much irrelevant, as they can be activated rather easily.The actual hardware modules, which are external, arenotin any promotion.

content: Quote from: mkosett on November 27, 2023, 07:42:12 pmVenerable as it has been, the DS1054-Z is made effectively obsolete by the arrival of the 800 series (although, history suggests that Rigol will continue to sell it for some time yet). Obsolete tech is not a good investment. Neither of course is bleeding edge tech but in this case, the 800 shares some pedigree with its bigger siblings (DHO1000/4000) and with it some of the software maturity. Still some way to go by all accounts but useable, especially by a beginner.That said, the second user value of the DS should start to fall accordingly, so if you're prepared to wait for the right time/opportunity, the economics of the choice may be different.

content: Quote from: Antonio90 on November 28, 2023, 05:38:20 pmYes, true, but the sale price of the unit is still $475, bundle or not. I am in that hobby boat, 1104X-E or the 804, knowing "upgrades" can be done to them and the price diff is about $100.I think if you add in the "mso" component in requirements, the SDS is a tad more friendly and has Bode.I myself though am looking to get the 804.

content: Quote from: Mechatrommer on November 28, 2023, 04:08:17 pmI'm guessing that's why joe rigol probes have "300V/150V" stamped on them.I'm also guessing that anybody who owns a 3000V, high energy supply is either aware of the dangers or has bigger problems than using the probes supplied with the DHO800.

content: Quote from: Fungus on November 28, 2023, 07:52:47 pmYou need think about this more.....Tell me what is rectified mains potential in most parts of the world ?~325 VDC which in a switching supply might have back EMF peaks superimposed on it and therefore for the sake of personal safetyandinstrument protection it is wisest to use 100x probes of which few would offer a 3kV rating.1000x probes are also not that expensive....

content: Quote from: tautech on November 28, 2023, 08:10:01 pmAll I said was that with a 10x probe it will take 3000V to kill one of these. That's a mathematically, factually, correct statement.At no point was it mentioned that OP was thinking of doing that,orthat I was saying it was OK to do it with the supplied probes.
