Hi,does anyone know about dso1511e+? It looks interesting. Support fft and square wave generator. From the video demonstration, it is better than FNIRSI-5012H.  https://item.taobao.com/item.htm?spm=a230r.1.14.329.61624c4ephX9fa&id=623012823156&ns=1&abbucket=20#detail

Just do not believe anything they tell exept perhaps price until you have real documented trusted ecvidences about example bandwidt and samplerate. They have many times stretched these. Example fnirsi 1GSa/s what is total lie. Also if some use chinese ADC MXT2088 it is 100MSa/s max 200 when interleaved. Same as 100MSa/s versuion Analog devices 9288  except that Fnirsi perhaps use 40MSa/s classified version running it with 100MHz clock.
Also it is well known that many Taobao sellers mostly do not know or understand anything what they sell and they can lie all specifications. Also feedback  is many times fake. In western world seller is responsible but in china here is partially still old outside street markets culture. Buyer is responsible. If buyer is stupid... well, it is easy money to seller. And this can see example in Taobao. In Tao there is Tmall side what is perhaps bit more safe. Still I have find some nice things from Taobao and I take these with me when I travel back to homeland. Example some amazing good SDR receiver (totally in different class compared to SDR-RTL toys)
Also NanoVNA V2 was good (and not at all cheapest one, quite honest and well done "clone"). Of course other case is also in Taobao if purchase well known brand machines like Haier better models and Gree better models and so on,  taobao do not of course make big brands bad. EXCEPT some sellers do not tell they purchase example from JD 7 day rules free returned items and try sell them as new ones. Also there can but Rigol and Siglent and they are same as always EXCEPT that they are not for overseas sales. Example some Siglent scopes what are bit more cheap but they are "webstore" models like SDS1000X-C with reduced performance, example half normal and sequence wfm/s speed but looks like E models.

Last time I try purchase some wires. Here they also many times use AWG dimension. But they do not know or care what is AWG.  Las time I buy some wire... AWG18... oh well outside dimension was roughly AWG18, not copper. Mostly if they sell AWGxx  in true it is 1 - 3 step down.

And yes, cheap set of SMA connectors and "nice looking" nicely advertised SMA attenuators. Shit. Total crap bottom class shit.
But then I purchase again. Functionally almost same things, and now quality is like top class western brands like Suhner - Rosenkranz - Lemo etc. But, price was also over tenfold and some even more. Still not as high as buy same quality in my homeland.


If you see price what is "too good to be true" it is mostly not true. Some peoples still think here in china all is cheap. Bullshit - yes it is still cheap. Nothing else.

[MiroS]

Bullshit - yes it is still cheap. Nothing else.

Even this may not be true.

I had to buy something and I found  that I can buy staff  cheaper  locally than on aliexpress . On top of this shiping cost ...

It end-up that I have locally 30% cheaper and it will arrive tomorrow  to me, 2 days ... not 2 months, no tax issue,  EU law protection (guarantee, retrun policy, no warries for fake  ...)

Here's a review of the DSO1511E+. Not very in depth
and, to my ignorant eyes, the UI looks a bit clunky.

[Ivanko1]

Does  DSO1511E+ better then 1C15? I think 1C15 is defenetly better then 5012H.)
Can some of them be used to repair power supplies? Currently measuring ripple and noise?

[lcp]

Minimum vertical sensitivity: 5012h=50mV, 1c15=20mV, dso1511=10mV.
Regardless of software or hardware, I prefer to choose dso1511e+.

Hello.
I'm new to the forum, but I've been around here for quite a long time.

I'm a happy owner of a Rigol DS1054Z, and it's the one I use normally, but sometimes I feel the need of something more portable, I really like the form factor of these cheap Oscilloscopes (and it's isolated nature is needed for some measures).

I really Know that none of these cheap DSOs is going to have the advertised sampling rate and BW, but as I've seen in some reviews, all of them seem to be able to handle 20-30Mhz BW decently. That is enough for my portable DSO needs.

But, for me, one of the mandatory features of a DSO is a reliable single trigger mode. And these scopes seem to all fail in this regard.

The ADS5012H looked very promising (I really liked the interface and buttons), but failed in this aspect because it lacked the required hardware (and also software in this case, as demonstrated by the better firmware developed by ataradov) to trigger reliably in single shot (at maximum sampling rate, without missing events).

I've seen some reviews for both the 1C15 and the DSO1511 (ADS1013D is not the form factor I am looking for, too big) and both seem to have similar capability. But no one tested the single shot trigger or showed the ADCs clock during single shot to see if the capture is continuous (not missing any trigger).

Does anyone know if the single shot mode is reliable in these models?

[visenri]

Both should be capable of sampling continuously and process triggers correctly, because both have quite capable hardware.
Both have ADCs connected directly to FPGAs.

So far, I've gathered this information (and I mark each feature with a + or - if it's better or worse than the other, IMHO):

FNIRSI 1C15

Hardware:
ALTERA MAX II + IS61LV12816L-10TL 2M-bit 128K x 16
GD32F103 up to 108 MHz - SRAM up to 96 KB

(-)Fixed square wave generator: 1Khz.
(+)Includes storage bag.
(+)Hotkeys (SINGLE shot, AC/DC).
(-)Joystick (some users reported they failed, and I feel rubber buttons are better and more comfortable to use)
   BNC is buried in:
     (-) Can't fit my bigger plastic BNCs.
     (+) Shock protected.
(-)Non-standard, extra long USB plug needed (I suppose you can cut the case if you want to use a normal one).
(-)It can save screenshots only to internal memory (May be also transferred through USB, but It's not described in the manual).
(?)I don't know if waveform can be moved in STOP mode.
(+)The manufacturer has a web page, manuals, and has released a firmware update.



SigPeak DSO1511E+

Hardware:
FPGA LATTICE LCMXO2-1200HC-5TG100I
CPU Allwinner F1C100s ARM926EJ-S (ARMv5TE) up to 533MHz - 32MB of embedded DDR SDRAM.

(+)FFT
(+)Square wave generator, adjustable: 0-2Mhz.
(+)Very compact.
(-)Reduced number of buttons, no hotkeys.
(+)Battery seems bigger, but both are rated at 3000mAh.
   Protruding BNC:
     (+) Big plastic BNC can be used.
     (-) Not protected against shocks.
(+)Regular size USB.
(+)It can save screenshots to internal memory and can be transferred using USB.
(+)Waveform can be moved in STOP mode.
(-)No manual, no manufacturer page, no firmware updates.
(?)Internal TF card slot for unknown purpose.

What do you think about the hardware?
Has anyone found any info of the SigPeak manufacturer?

I bought a dso1511e+ last month and I really like it. You can use the "Power" button to combine other buttons instead of hot keys.

Thank you very much for the information, I had already seen the videos, but not the shortcuts sheet.

These shortcuts compensate almost completely the lack of extra buttons (I only miss the single trigger one).

Where did you get the shortcuts image, is it from the printed manual?
Is there any information about the manufacturer in the printed manual?
Did you test the single shot mode with a very short event (1us pulse for example) occurring only once?

Yes, but I did not find more information about the manufacturer in the manual.
The single trigger mode works well for me. It did not miss any events.

Ok, thank you, I ordered my dso1511e+ last night  .

When I test it, I'll put here my mini-review.

Now, I'm looking for an storage bag for this new toy!

Looks interesting.

Should probably have it's own thread...

Have you received it yet? I'm interested in the FFT function. I want an fft display for my audio analyzer and would like to see how well it works. There is a demo video but that's using it as an RTA not a spectrum analyzer.

Yes, I received it last week and I've done some tests and posted the results here:
https://www.eevblog.com/forum/testgear/dso1511e-review/

I did no test of the FFT function.

Right now I'm doing a simple test using the included square wave generator and it shows that it does not seem to show accurate-reliable-measurable results in the whole audio spectrum. I suppose that the limited sample memory is a limiting factor here.

Very poor also from a usability point of view:
I've seen no cursors or on screen information to take frequency or amplitude measurements.
Also, no indication about current amplitude or frequency range depending on the time base.
Nothing, just the FFT graph, no extra information present in the manual.

I ordered one from eBay for $94 delivered which is an OK deal. I hope I can find the FFT useful. If not it will go in the bag of other stuff that was not too useful. . .
