Only the bottom menus can be hidden as they don't show the more important RHS operational settings while the bottom settings show far less important info unless you're documenting screenshots or coming here seeking help where the more settings you can show is more helpful for us to give guidance.

I have the spec sheet and the manual for X-E and X-U and for the small increase in price the X-E is a no-brainer (US is about $100 difference and here in the UK it's £50). The manual shows the menu on/off but the operation isn't described. It makes perfect sense that it turns the menu at the bottom on/off and it's close to that area too.

I couldn't find anything to suggest that the X-U has less capable processing capability (it would have been nice to know that they didn't save a few cents on this) - I get it that the input is simplified and doesn't have a second sampling chip. At this price point sampling with two chips is cool. So pretty much sold on the idea of an X-E. I can see that the X-U will be an option if the budget was for 2 channels because it's a small increase to go to 4-channels.

I get that there is a hack for setting it at 200MHz BW, perhaps there are downsides to doing that? I read that the supplied probes rated at 100MHz are actually quite good ones, so no need to rush to replace them even with the hack (I was nervous about doing it but if it's reversible, why not?).

Simon, you have a good handle on specs and capabilities and certainly with X-U pricing little more than the 2ch 200 MHz SDS1202X-E it's a no brainer to get the 4ch X-U if the additional BW is not required. But the SDS1104X-E is a better spec'ed and more capable scope.

I feel the X-U capabilities are only throttled back rather than a result of lesser HW although the likes of the missing webserver, Bode plot and lesser FFT specs matter to some however they are another $100 for the 4ch X-E but you also get the additional ADC and its additional 7 14 Mpts of mem support.

When using either there is no noticeable difference in performance for general scope use. One only needs to watch the sampling rate when all channels are active in a X-U at higher frequencies to keep an eye out for aliasing.

To me that's all definitely worth $100 and are some of the best distinguishing features for Siglent.  A first-time user may not notice for while, but those are all pretty handy if you think about them.  For example, USB WiFi + webserver = way to safely float scope!  >:D
A 3.5 digit 4.5 digit 5 digit 5.5 digit 6.5 digit 7.5 digit DMM is good enough for most people.

If you totally overlook the fact that it has an isolated output with a ±42 Vpk isolation rating.
Please do show us a similar device for similar cost.

That's isolation with respect to earth ground, right?

The UTG962 would qualify since it's driven by a wall wart (and thus can be driven by a battery for as much isolation as you want), but since it can't be used with the Bode plot function of the SDS-1104X-E, it doesn't count.

So this is a fair point.

Correct.

Now that the isolated SDG5000 series is withdrawn SAG1021I is the only isolated AWG Siglent produce until they release the SDG7000A however they will certainly not be a widely affordable priced instrument like SAG1021I is.

This thread has drifted somewhat from its title..

Siglent SDS1202X-E or Rigol DS1202Z-E

So, back to the original question. Am I correct in assuming [as its near impossible to find the answer simply] that the Siglent SDS1202X-E IS the 'same' as the SDS1104X-E, just its 200Mhz and 2 channels? Is the rest the same hardware and software? Does the 2 channel version miss any of the software features?

Likewise with the DS1202Z-E vs DS1054Z - same basic hardware ?

Oh, and whoever designed the website at https://siglent.co.uk/ needs to realise web design has moved on since 1997 and MySpace.  :-DD

Several.

Thants.

Please kick whoever thought of your model numbers/suffix.  |O  :box:

No the SDS1202X-E is not the same as the SDS1104X-E/SDS1204X-E, below are some of the differences.

Single ADC so no Dual 1GSa\s (It is 500+500)
No support for the optional AWG or DSO
No Bode plotting
No Browser control

I'm sitting here thinking if I would ever need Browser control, or Bode plotting. I assume to Bode plot you need the optional AWG?

You need an either the optional AWG or a supported Siglent standalone AWG. (There are work arounds with other brands of AWG, but hardly plug and play)
If you don't need browser control (Useful if you have a DUT and want to monitor it from another room) or bode plotting
then ask yourself would you like 2 ADC's for dual channel 1GSa\s and also would 4 channels be useful?

So its more like a 2 channel SDS1104X-U.

Yes.
Except for SDS1202X-E has higher sensitivity and better FFT.

The X-E range appeared after the SDS1kX range that had 8" displays and 50 Ohm capable inputs however they didn't have the Xilinx processor that has taken over in all these cheap scopes and permitted snappy operation and additional functionality and improved UI's.
SDS1202X-E led this development and SDS1104/1204X-E, SDS2202/2352X-E and SDS1104X-U followed.

The SDS1002X-E range was to be released to the west in several different BW's however when Dave got a prerelease SDS1102X-E and showed how to hack it to what we now know as SDS1202X-E Siglent withheld all other models and only released SDS1202X-E to the west.

Simon, you have a good handle on specs and capabilities and certainly with X-U pricing little more than the 2ch 200 MHz SDS1202X-E it's a no-brainer to get the 4ch X-U if the additional BW is not required. But the SDS1104X-E has better specs and is a more capable scope.

I finished my "homework" for the weekend - reading through the entire SDS1000X-E/U manual. Today (Monday) I opted for the SDS1104X-E and it should be arriving tomorrow.

Update

Arrived as expected yesterday (Tuesday). I had a brief "play" and I think they have done a good job with the SDS1000X-E series scopes. It has a fan that is always on which keeps the scope cool and you can tell by the exhaust temperature that it's required. It weighs (without leads/probes) over 2.4Kg, so that's almost 1.8Kg more than a Hantek - this surprised me. Good as it is to get "stuck in" with the manual, it will require more reading, for sure.

Hantek RIP (02.06.2021 - 16.06.2021) :-BROKE

Today (Wednesday) my Hantek DSO2D15 was posted back to Amazon UK. I also sent the 250MHz Hantek probe I ordered separately (because Hantek only provides one probe) back. Amazon notified me that both refunds should be with me in a few days (not going to be out of pocket). As they say (and Jack Yellon wrote), "Happy days are here again!"
