content: *** I posted this in "metrology" initially, but was scorned about it being OT there, so here it goes... ***I'm looking at Rigol DHO800&900 series against Siglent's SDS800X-HD & 1000X-HD - top models within the line ( 4 channels, may available bandwidth)1. AWG and logic probe asde, looking at pure scope functions is there any substantial advantage on Rigol's side ?Rigol has only 1.25Gs/s max sample rate vs Siglen't 2Gs/s. And this evaporates quickly with number of active channels - so it halves at 2 channels and quarters at 3 ch or more.Even though Rigol924 has declared 250MHz bandwidht, this obviously has to falls with 3 or more channels. SIglent's has only 200MHz bandwidth and it has more sample rate to begin with.Siglent also has 2x memory depth - 100Mpoints vs Rigol's 50 Mpoints - both models share them for all channels.So, is there some significant advantage on Rigol's side ?2. What's the fundamental difference between Siglent's SDS1000X HD and 800X HD series ? 1000X HD series is priced significantly higher and I can't figure exactly why... 🙄3. Is there any other significant competition in this price segment ?

content: I previously owned a Rigol 1054z. I was thinking the Rigol DHO804 would be it, but after reading and looking at things finding out the Siglent SDS804X HD was available, that became my choice.The better specs was part of my choice, but also it was a more traditional form factor and UI also swayed me. Everyone has different opinions. But I'm sure this will be an interesting thread.

content: Trying to startanotherflamewar.Neither is "better", it's a question of taste. Choose the one you enjoy using the most.From what's been argued in the past: Rigols are easier to use and get results faster, Siglents have more parameters and things to fiddle with but you need to know what you're doing and enjoy fiddling with parameters.The one that suits you best will depend on YOU,andyour history with 'scopes. Nobody can answer that for you.Both of these are "entry level" now. If you're an advanced user then maybe spend more.PS: You don't have to buy the high end model of either brand. Buy the lowest model and unlock it.

content: Wow ! What an ingenious answer ! Buy all the options, play with them and then actually use the one that suits you best !Who could have thought of that ? I guess that's what the forums are for, right ? 🙄

There is a big list-o-differences between the SDS800X HD SDS1000X HD right here:https://www.eevblog.com/forum/testgear/sds800x-hd-review-demonstration-thread/Side comments:Rigol NA typically has a huge clearance section with free shipping. Earlier today there was a DHO804 for $279. Proceed with "liberation" and you'll get a lot for your money. But they can be known for big bugs and being slow to fix them.Siglent seems more "mature" as a company and with their products. "Liberation" is also common of course.The 800 series from both companies are a bit small if you're planning to do serious work.

content: Quote from: Hella_Wini22 on September 08, 2024, 06:04:51 amYou missed the Rigol DHO 1000X-HD which compare with Siglent SDS 1000X-HD. 2 GSa on both but Rigol does not have LA capability.To see the difference between SDS1000X-HD vs SDS800X-HD you need to look at them. That is the main difference + 50 ohm input. If that worth the price this is another discussion.
