content: As models changing fast, please recommend,Siglent and Rigolscopes at around (a)400and (b)1000 USD for 4 channels.Logic probe add-on seem expensive (200 to 400 USD). Any choice for a third party "finished alternative", not solder kit.Are both price points 10 or 12 bits?Whatextra functionsthe 1000 USD has over than 400 USD, apart from bigger screen.Many thanks

content: Your Siglent 12bit low cost DSO options are:SDS800X HD, the lowest cost 4ch model is SDS804X HD.SDS1000X HD, the lowest cost 4ch model is SDS1104X HD.The SDS1000X HD models offer probe sense and 50 Ohm inputs along with the larger 10" touch and mouse capable display however both model series support touch and mouse along with a fully capable webserver.SDS1000X HD have a RTC whereas SDS800X HD support NTP time when connected to the internet.They both use theSPL1016SLA1016 16ch MSO module which to my knowledge has no copies....yet.

content: Quote from: Wilson__ on August 25, 2025, 08:00:37 amI prefer a seperate logic analyser, take your pick from the bunch of usb analyers available. I find that I rarely need to view analog and digital correlated on the same screen, and prefer the PC interfaces for logic analysers compared to scope.I'm selling a bigger screen 12-bit rigol which offers quite good bang for buck;https://www.eevblog.com/forum/buysellwanted/fs-uk-rigol-hdo1074-12-bit-4-channel-oscilloscope/

content: There's a couple generic options for the SPL2016 you can buy on eBay. I have one for sale in the for sale section, but it's probably not worth the shipping cost to the UK.I hate anything to do with Rigol, but if I was going to get one, it would be from voltsandjolts.

content: Is RigolDHO914andDHO924good nowadays?Heard that the 800 series had some bugs when newly released. Wonder if 9xx series is/was affected?I believe DHO9xx logic analyzer firmware is enabled by default and third-party PLA-2216 compatable is available.https://www.eevblog.com/forum/testgear/low-cost-compatible-rigol-pla2216-logic-probe-for-dho900-(and-hacked-dho800)/DHO9xx fits nicely under LCD monitor for firmware + hardware development.

content: HiThe new Rigol series are not good, problems with the front end and also Android crashes.Lack of accurate and correct information on the chips used

content: Quote from: KAKUL on August 26, 2025, 05:38:22 amNot true. Mine has never crashed that I remember.(and even if it did, the system restarts the app in a few seconds exactly where you were - you can use this to change models between DHO800/DHO900 models in a few seconds, just change the magic file and kill the main app using Android debugger commands over WiFi. It restarts as the other model)Quote from: Wilson__ on August 26, 2025, 05:13:04 am9xx series is the exact same hardware/firmware as the 8xx series, the only difference is the extra connector on the front of the 9xx. Any model can be switched to any other model by changing a single file on the internal disk. You can turn a DHO804 into a DHO924 by cutting a hole in the front and adding the connector.The 900 series is a bit underpowered when you turn everything on. Not very recommended if you intend to useall the features simultaneously. Think of a Swiss army knife - you don't open all the blades at once or you'll cut your hand.You need to look at your priorities:* If you mostly do digital/logic then the Rigol MSO5000 is much better than the DHO900.* If analog is your main focus and you're spending 1000 USD then Siglent is probably better.

content: This looks nice, big screen, high sampling rate, now promotion bundle to activate two AWS channels and protocol decode.I did not use this before. What effect is 500,000 wfms/s compare with other at 1,000,000 and 1,500,00?Document says this number determines "how long a user has to wait until the scope will finish capturing and find the glitch"? How this function works for capturing glitch as in the photo?The spec says, "MSO5000 series digital oscilloscope can provide the waveform capture rate of up to 500,000 wfms/s, so that the glitches and infrequent events in waveforms can be quickly identified"8G samples per second is really upper class. Is 8 bits resolution good for debugging digital signal SPI, I2C? To verify setup/hold timing is valid for SPI, 10 to 30MHz. Signal Hi/low voltages are valid. No two devices talking at the same time due to software mis-setting, etc.

content: How much is the noise of MSO5000?Just like to know the number.Likely, not an issue for design and development, fordesign-verification/debug of digital signals, SPI, I2C, etc. Some new generation 12 bits scope is 20 uV and I do not need that extreme.

content: Quote from: Wilson__ on August 27, 2025, 04:01:25 pmOff the top of my head, I think I see something in the order of 10 to 15mv sometimes. Not great but not an issue for the use cases you're looking at. I've a 'bandwidth liberated' MSO5k and it's just fine for the digital/microcontroller work that I do, which is similar to yourself in that it's generally low speed timing and integrity verification (usually below 100Mhz). Notionally, the higher sampling rate makes for better glitch capture, though I've not really had the need for that so far.I'm not affiliated with voltsandjolts in any way (no kickbacks here) but.. I'd take his DHO1000 series before I'd consider a new 800 or 900 series, if you decide you'd prefer a 12-bit model. Altogether a better value proposition, imho and you also don't mind losing the VESA mount and a bit more bench space.

content: Quote from: Wilson__ on August 27, 2025, 04:01:25 pmNot great, but it makes no difference for digital circuits and you get a ton of memory and 350MHz bandwidth in exchange.(nb. Get the base model and hack it to max features, you can even buy the 2-channel model and unlock the other two channels if you have a couple of spare probes lying around)Edit: I just looked on their web site and the 5072 costs the same as the 5074. Go figure...
