Siglent SDS1104X-E vs. Rigol DS1054Z Advice?

[KungFuJosh]

Yeah you get that if you're in too much of a hurry capturing screenshots. A USB stick with an LED can let you know when the Save has finished.

BTW, the channel tab for the screenshot of the 100x probe earlier shows input attenuation set to 1x as you hadn't set that up before saving however it won't make any difference to the displayed overshoot.

Haha, yeah, I hadn't found that setting yet. I did retry after finding it but, as you said, the results were the same.

I'm not worried about the screenshot thing; it's a good thing. On the Rigol it took 3 to 5 seconds to record the screenshot and you couldn't do anything while it was doing it. The Siglent is basically instant and you can still use the scope while it's doing it anyway.

[KungFuJosh]

The Rigol does the exact same thing. 

(push the horizontal timebase knob and you get zoom mode)

Cool! I dunno why I never pressed that button on the Rigol. lol

[Fungus]

I didn't even realize it captured anything yet, so I hit the button again and captured two images. Oops.

Or ... a good user interface would show a popup confirmation message on screen.

It does, but it's fast and I looked away. Speed is good.

OK, I think I can see where this is heading.

You were too repulsed by the Rigol's ugly case to actually learn how to use it.

Psshhh. You're going to turn ad hominem because I missed one button? I've been very fair regarding the pros and cons of both units. You're far too defensive of a product you didn't design. The Rigol is an inferior product. Get over it. It still has its place.


...in the dumpster.

Have you tried viewing the X100 trace at the same time as a X10 trace on the same 1kHz signal.

I can imagine(guess!) that the scopes 1kHz is expectiing to be driving a 15-20pF scope probe, rather than just the 5pF of the X100. And of course 3V pp is very low signal for a X100 probe, keeping square waves perfect over a very large dynamic range is very difficult.

Hey! The Rigol has an overshoot measurement, pretty handy while calibrating probes! I got it under 1%, don't remember the exact number, but that suggests about 1 LSB, which seems good enough for me.

Oh, dear. It looks like the Siglent is missing that one!

Edit: My bad, it's there, Siglent calls it "FOV" instead of "Overshoot"



FWIW: I just counted the number of measurements on the Rigol. It has 37 compared to the Siglent's 28.

Well they do both have their pros and cons. Point for the Rigol if you need more measurements. Does the Rigol do standard deviation also?

[JPortici]

Translation for simple people like me:

Hi Res: Scope lowers bandwidth and averages some crap to pretend to be better quality.

Average: Scope removes data and averages some other crap to pretend to be better quality.

Despite how you translate it at some time each of these tools will be found to be indispensable ! 

Maybe, but you gotta admit it's a pretty good translation.

Hi, i use hi-res also as a digital filter
This is when i don't want to be bothered to do "good" probing because i want to probe several signals at a time and i don't have four hands, so i can get rid of high frequency noise.
high frequency noise can come from MCU programmer during debug, laptop power supply or some bastard here with an FM repeater that is messing up all my measurements, just to make an example.

First i make sure that with good probing the signal is indeed as it should be, then i resort to lazy probing and enable high-res.

PS: a friendly advice, fungus has been in my ignore list for a long time

Does the Rigol do standard deviation also?

Doesn't look like it, it shows max/min instead.



(Stats mode shows the box at the bottom of the screen)

That's all good. I'm sure both companies can add more math functions if they want to.

Lazy probing, now you're speaking my language!

Oh, wait... it has it. You have to select the type of statistics. 

[Fungus]

I haven't really delved much into the statistics before. There's a lot in there, you can actually enable a rolling graphical display of measurements over time to go with the stats.



(they aren't changing much there because it's just the probe compensation signal but the yellow lines are advancing across the screen)

[KungFuJosh]

That's all cute, but with the Siglent, there's more usable screen space, a useful 1M FFT, and you can view all of that with measurements and statistics on screen all at once...

[KungFuJosh]

...but holy crap does it annoy me every time I see "Curr" on screen instead of Mem for memory depth. Morons.

You know that lies do not walk long... so why. Or is it just only fun.

Siglent 38.

And WHAT "one" is Siglent missing? 

FOV  Overshoot after a falling edge
ROV  Overshoot after a rising edge
RPRE Overshoot before a rising edge
FPRE Overshoot before a falling edge

[Fungus]

FFT+stats+measurements in a more sensible layout:



OK, it's only 16kpoints FFT. Siglent wins there.

[Fungus]

Siglent 38.

Try counting again...

[KungFuJosh]

FFT+stats+measurements in a more sensible layout:

That's a matter of opinion. I checked the thesaurus, ugly isn't anywhere under "sensible." The FFT on the Rigol still isn't 1M or very useful. Look how small that usable screen area is by comparison. You need a screen magnifier with the thing.

I didn't buy my Rigol for the FFT, I'm just comparing the two for fun ...

FFTs need detail so all 8-bit ADCs are inadequate, IMHO. 1Mpts helps but it's only a band-aid compared to having more bits.

Siglent 38.

No, I know but it is not my head ache if you can not read and count. Where is your blind spot.

Rigol do not have Stdev measurement. (I do not mean measurements statistics dev but signal data Stdev what is very useful feature. If know where and how to use it.

You can start lesson one here, page 14,  and count: Take your fingers for help. Oh but wait...how you count to 38 using fingers. Perhaps you can mark every 10 so that instead of 28 you finally get 38... exercise...exercise...

Sorry. My band for not looking "FOV" up in the Siglent dictionary. I guess I'm just used to "Overshoot" being labelled, um, "Overshoot".

(Is there a reason they call it that? There's obviously enough room in that menu to just write "Overshoot". Rigol managed to squeeze it onto a tiny button.)

Oh, snap! Looks like Siglent gets the math point too. 38 math functions for Siglent, and only 37 for Rigol.
