Hantek DSO2D10 - short review
« on: February 03, 2021, 12:46:52 pm »
" alt="" class="bbc_img" />The Hantek DSO2D10 is a low-cost two-channel digital oscilloscope with a built-in arbitrary signal generator. It belongs to Hantek's new family of low-cost oscilloscopes. Models are available with a generator - denoted by the letter 'D' and without a built-in generator - denoted by the letter 'C'. The family includes oscilloscopes with a claimed bandwidth of 70, 100 or 150 MHz. The described model has a declared bandwidth of 100 MHz.
 
We have to admit that, for a device costing less than $200, the parameters seem quite satisfactory. My doubt is that in models with declared bandwidth of 150 MHz the sampling rate is only 1 GSa/s (500 MSa/s in dual channel mode). This seems too low to reproduce the waveforms well.

Oscilloscope:
Bandwidth: 100 MHz
Sampling rate: 1GSa/s - single channel, 500MSa/s - dual channel
Maximum record length: 8Mpts - single channel, 4Mpts - dual channel
Time base mode: YT,XY,Roll
Rise time: 3.5ns
Mathematical functions: Add, subtract, multiply, divide, FFT
Clipping windows for FFT: Rectangular, Hanning, Hamming, Brackman, Bartlett, Flattop
Screen: 7", 800x480 px

Built-in generator:
Resolution: 12 bit
Sampling rate: 200 MSa/s
Sinus frequency: 0.1Hz to 25 MHz
Number of available arbitrary waveforms: 4
Arbitrary waveform length: 8 KSa

The decoding of UART, LIN, CAN, SPI, IIC transmissions is a positive feature. Measurement can also be triggered using the above interfaces. Although the record length of 4Mpts (for two-channel mode) does not allow observing long transmissions, the possibility of decoding messages should be considered a definite plus.

I placed my order in China in mid-December when the oscilloscope still had preorder status. I had to wait for shipment almost until the end of January. The device itself arrived in good condition, solidly packed. I had the package at home about a week after shipment.

The first impression was moderately positive - the build quality is simply correct. Nothing creaks, nothing squeaks, the plastic is thick and feels solid. The knobs work smoothly, with a nice "jump" but could be more stable. Slightly annoyingly, the USB connector is mounted upside down. Apart from these details everything seems to be in perfect order. The device itself looks just nice but that's a matter of taste.

After starting it up and playing around for a while, we can say that the oscilloscope works as it should. Unfortunately, I do not have access to an external generator, so I based my measurements on the one built in Hantek. Certainly, the multitude of functions is satisfactory, in the oscilloscope itself you can adjust many settings related to display, data acquisition or measurement settings.

During several hours of play, it happened twice that some menu function got "stuck" - it was impossible to change it. Entering another menu and returning to the jammed function helped. It also happened that the "Auto set" function selected completely wrong settings.

Overall, my impressions are quite positive and, for the price, the oscilloscope behaves correctly. The problems detected so far are related to the oscilloscope software, so one can hope that the manufacturer will fix them in a newer software version.

Oh, good, someone with the actual unit.

Can you check a couple things:
1. Is there a fan? How is the fan noise? Is the fan on all the time?
2. In a single trigger mode, does pressing "RUN/STOP" button re-arms the trigger?

I know that (2) is like a given, but apparently Owon did not think so, and it is very annoying.

@ataradov I have a DSO2D15 I received in the end of January.

1) There is no fan, the unit uses surface mount chips that have passive heat pads onto the PCB below them. They all run quite low power, with the whole unit being totally silent and running only lightly warm.  There is the usual fan spot in the metal chassis if you wanted to mod in a 5V fan from the power supply.

We've captured and discussed a few internal pictures in this thread:  https://www.eevblog.com/forum/testgear/new-hantek-dso2x1x-models/50/ (see page 3)

2) In Single Trigger mode, pressing the Single SEQ Button again will rearm the Single sequence trigger, and light orange to show an armed trigger. There is also a Force Trigger button if needed.
Pressing run/stop will switch back to auto/normal capture mode.

Its got most of the useful trigger options. So far so good with it, especially considering the class and price its built to. Only issues I have encountered are likely future software updates and improvements. Mostly with the odd sample rates it picks as you adjust the time base / memory depth. There needs to be an option to (re)set the sample rate to what it should be, besides the hitting the auto set button, or default setup button to put it right again.

Great! Thanks for the response. We'll see how long SDS1102 trigger can annoy me before I give up. No fan is the key feature here for me.

Here is a more full internal view I didn't post in that other thread, with the internal shield cover removed. You can see the open mount point where a fan could go, if you wanted to add one.

Quite the opposite, I don't want to have one.

But looking at this picture, it looks like the scope is quite wide. Once thing I like about Owon is how slim it is. It takes very little space.

A bench scope needs to be deep enough to stand up without being easily tipped over.  What I'd like to see is an over/under format so the entire device is no wider than the screen.  That would save bench space in a direction I care about.

My only experience with Hantek was a 6022BL.  The software was so poor it never ran on my PC.  Yup, the software just would not run at all.  You gotta respect a company that ships products entirely reliant on the program running on a PC that simply won't run. 

Of course they have zero support and the documentation is only slightly better than none at all. 

I'm not at all sure why anyone would consider a product from such a company.

I would not consider anything PC-based from any company.

This is a standalone unit with is a finite set of features. It either works or does not. If reviews tell me that it works and does what I need it to do, then I don't see why I would not consider it.

How’s the waveform update rate on screen? It was quite slow on DSO5102... Did they improve on that?

The allwinner Processor holds it back a bit, but the screen refresh rate is quite usable. Looking into the hardware, and the interfaces, there is quite bit of potential for improvement s in software performance. My main concern I find is that measurements are based only on the subset of data the cpu pulls from the capture engine to update the screen with.. so measurements change based on your time scale setting. You need to adjust things to get a clean waveform to get an good measurement. Again this could be improved in software. The mystery remains the LemonTree2090 and its capability and role in the capture engine. At the moment it appears to be just acting as sample capture memory, when it's size would suggest so much more capability for processing independent of the Allwinner. In all respects I can see in the hardware design, this scope seems capable of more far more speed than its software is currently allowing.

I am trying to setup this oscilloscope in XY mode such that it has X=X-Y and Y=Y... possible? Basically I want that purple axis that is generated by math function to be X axis and it is calculated by X minus Y and Y remains Y. There is no way to use the calculated axis as one of them in XY mode?

I don't think that's possible.
The only way I can think of is to load the samples to the PC via SCPI and do the calculation and display there. But it's not easy, if it works at all.

Btw: The main thread for this scope is here: https://www.eevblog.com/forum/testgear/new-hantek-dso2x1x-models/
