I just bought an SDS1104X-E and I'm still coming to grips with it, as it's my first scope, but I think it was definitely worth the extra cash for the other two channels.
Well, don't want to be that guy, but Dave's April fools are very early. Based on the upload time shown on my computer, even taking time difference into consideration, it still was uploaded on march 31st (11:30pm or so)
I just bought one of these. The menus are significantly different. I have everything set up, but no decoding is shown. I don't have a "display on" button in the menu (like at 3:13)..as a matter of fact, that menu only has one page. No list button, no format selection. Guess I'm going to have to find the manual..
Siglent makes some nice lab gear, but the programmer for the rotary might be the same as for my Siglent power supply: no acceleration, as it is really nice implemented in the Keysight scopes, and if you turn it too fast, it even misses positions or goes backwards for some ticks. Maybe I should ask them if they need a better firmware programmer.
Frank Buss encoder programming is always a tradeoff between debouncing and responsivity. Maybe they just use crappy encoders. (It's even worse in their signal generators, the encoder is only usable if you turn it slowly.)
For the usual rotary encoders with quadrature output, bouncing is no problem if you program it right, like sample the two outputs with 1 kHz and then use a state machine to calculate the transition, instead of what beginners do, like use one output as an interrupt source and then sample the other output, which is a sure way to miss pulses when it bounces. I've used cheap mechanical rotary encoders which bounces a lot without problems, even in the idle position, which I can filter with the state machine without extra code just by choosing the right table values, see here: www.instructables.com/id/Using-a-Quadrature-Encoder-with-an-ATtiny-2313-and/

too many comments on that $300K trash find .. BUT can you do the TAP test on it to see if it suffers from the same problem as cheep (in comparison too $300k) scopes ... like you did in EEVblog #983 ... or if $300K buys you insurance from these problems
The 1102x can only record 0.3 seconds in serial decode mode. Max. mem. depth is only 1.4 meg. points (tested on 9.6 kb/s). Does the - E model also have these bugs?
i bought the siglent 1202x-e I dont need 4 ch and this scope blows the 1054z out of the water as long you dont need 4 ch. Asking for a comparison of this vs the rigol is silly

I just bought an SDS 1202X-E thanks to your videos. The serial decode is what I really wanted right out of the box. It's been a great unit so far!!
I would love to see a shootout of all these new low-end (?) scopes versus the Rigol 1054Z

Hello Dave! Nice video as always. What would you recommend between this scope and a Rigol DS1054Z?
Now, of course, this is a serious video, because in Daveland, it's already April 3rd
Nope, Still April 1st
Random Model Making Channel careful, you'll have Dave giving another timezone lecture

Is there an ETA on a review of the SDS1000X-E or did I miss it?

What 4 channel oscilloscope 100/200 + 16 channel logic analyzer would you recommend? Siglent? Thanks for your videos!
And "the other budget scope" does it well even at 100ms/div (this one won't let you do that because it disables the decoder @ > 20ms/div)
Does this scope also have the "50Hz squarewave hardware bug" which the 1102x has?
Elektronik I sent e-mail to Siglent and got answer that it is fixed with new firmware (1102x), but I am not 100% sure.

Not in Kiritimati!!!

Hey for spi decoding siglent sds1104 or rigol ds1104 better choice
Or logic analyzer?
Please suggest right choice....
Where the X (not X-E) errs is when you do that at slow sweeps (20ms/div) and then zoom in the data you get garbage (at 57Kbaud or more).
Nice.... but need more channels. Really want the serial decode with respect to some signal of interest
So, if it's a budget scope, how much would it cost?
Did you find this DSO in the dumpster or is it a sponsored one?
Please tell me this thing costs more than the standard SDS1102.

Dave the red boxes are errors!

No. At least 3 years later, the 1202X-E doesn't have it.

First!!!! The decoding works well on my 2102, has a few bugs which I pointed out to siglent , they fixed some of them (the ones they could replicate)
I try to use your information
APRIL FOOLS!
I'm not falling for that trick again.. April Fool !!!!!
April fool's joke, no way this thing is decoding with all that rust inside.
second
you dont know what you are doing. It will do real time in auto, you have the wrong signal settings.
Wow. Great april fools' joke.
Is this a joke?
