Title: Hantek2000 bugs and wishes (2c42,2d42,2c72,2d72)
Edited by AxGxP at 2019-12-13 07:00

Fixed firmware avaliable:
[attach]3311[/attach]

My Hantek2c42 often doesn't pass the calibration. It freezes on it! I wait for more then 5 min, nothing changed. Fixed!
A problem also with DMM. In "DC mA" is not zero even when i cross the probes. It always show 0.02-0.05 mA, without probes also. Fixed! (the flux between +battery (J1) and shunt resistor 1 Ohm wasn't washed)

Please make some changes in the new firmware:
0. Add some functionality to export saved oscillograms to PC.
1. Add Menu hide (toggle) on second pressing "Menu", "Trig", "Channel", "Time". (MyFix)(HantekHTXAxGxP0001)
2. In Channel mode change LEFT<->RIGHT buttons, in Time menu UP<->DOWN! (MyFix)(HantekHTXAxGxP0001)
3. Add horizontal scale settings during operation. At least option to see all the signal on the screen but not a part of it! (somesing like 1:1 or 1:10 in analog scopes)
4. Make working icon about channel coupling AC,DC, Gnd. (~,–,x). Fixed! (2019022001)
5. When menu is hidden. Make changing of arrow buttons usage: "F1" - CH1 changing, "F2" - CH2 changing, "F3" - trigger changing, "F4" - time changing. Without showing this menu! Only arrow buttons function changing! (MyFix)(HantekHTXAxGxP0001)
6. Change word "Double" to "Both" in triger edge selection.
7. DMM Buzzer mode. Bug with sound, after shorting it say "Pi-pause-piii" but not single "Piii". Very slow measurement near 8-10 sec before value is stopped. It better to mesure voltage, not resistance.
8. In "Trigger" mode change buttons "<-" and "->" form changing trigger level to changing trigger position, like it does in "Time" menu.

What about adding some new not documented features, for example X-Y mode etc. Can it be possible? Fixed! (X-Y pressent in2019030201)

399V problem is solved. Resistance measurement was with error.
There was burned resistor R15 (1k).
It was a little brownish, and was changed to new one.

关于bug的反馈：
二极管档测量LED灯，灯不亮，不显示导通电压。二极管，三极管测量很鸡肋。
万用表功能经常处在假死状态，比如测量电阻时，偶尔用手碰一下，或者立马换一个电阻，就会像是死机一样没反应，需重新按键激活。
示波功能：采集刷新太慢，表现为：测试晶振时，正玄波不圆润，变形，同时频率显示不停的变化幅度太大。

有什么方法请告知，把二极管测试提高到2-3v。我接受改装，这个功能在维修工作中占据着很重要的位置。
还有下面的问题：
1：就是设备连接到上位机以后，拔下来，示波器会初始化为出厂设置。
2：示波器的波形，测试晶振波形时，不是很圆滑的正弦曲线，感觉有点变形，且可以看到频率在一直的刷新。一般示波器测试12m，基本上就是12.或者多一点点，很稳定的数字，这个示波器就是11m--12多，这样不停刷新。
最近没怎么使用，忙完这段时间，深入使用后，我通过微信发送售后，总体来讲此款示波器做的是比较符合需求的，开关机速度，人性化，上位机，功能等。需求做的没什么问题，很符合使用需求。只是细节方面希望更提高一点。

Dear amy

I understand that it is impossible to execute all the Wishlist, but the display in the measurement of the amplitude value was a more correct decision. If we add to it the root-mean-square value of the amplitude would be generally wonderful.
And the minimum and maximum is needed mainly for measurements in the car and in everyday tasks of repairing radio equipment only interferes. And you can also make a long press of the menu button to close the status bar.

Feature request:
Possibility to route DMM inputs to the scope display, to get a visual readout of lets say amperedraw over time (for instance start-up current of a device).

Another device that does that:
ET201
C:\Users\Lars\Downloads\et201.png

And a data logging function, either "time-lapse" storing data at a given timeinterval or trigger-based that only stores a snap each time a threshold is reached. Could be integrated in the PC software, not necessarily in the Hantek2000 itself.

Hi

I bought this Scopemeter  2d42 mainly to use it as a multimeter I found that
on DMM mode it performs very slow when it comes to reading
Resistance and Capacitance.

Is there something that can be done to fix this? maybe in the firmware ??

Thanks

Hey amy. There is a wish to refine the firmware. If I use a generator and an oscilloscope for the circuit under study and I need to quickly change the frequency of the signal, then I cannot do it.

For example.

I need to scan the oscillating circuit in frequency from 35.00 kHz to 45.00 kHz. I run the AWG at a frequency of 35.00 kHz, go to the Scope page and look at the picture. Ok. Then I return to the AWG page and I want to set 35.01kHz, but I can't! First I need to go to the tab such as the "Amp" of the generator and then return to the "Freq" tab.     
And only after that I can change the frequency of the signal.

Some way to hide (toggle) menu on the screen. For example by pressing menu button second time.

Please swap buttons left and right in channel menu mode. LEFT button must increase volt/div. RIGHT button must decrease volt/div.

Please swap buttons up and down in time menu mode. UP button must decrease time/div. DOWN button must increase time/div.

Author: wolfallein    Time: 2019-8-1 20:51
Dear Amy,

It is very good that you still improving the firmware of the oscilloscope. For me, there are three things that I miss for my daily work:

1. FFT in one of the channels on the scope screen. I know that it can be done on the PC, but would be good to have it on the oscilloscope screen as well.
2. An SDK with a DLL like you have for some oscilloscopes to integrate it with LabVIEW for instance. I think that your PC software already uses a DLL to communicate to the scope, it is just necessary to document the functions that can be accessed by a user program.
3. A small data logger for the DMM. A feature to record a few points in specified interval time, like minutes, and make a small graph on the screen. When I bought this oscilloscope I looked to the manual (v.1.4) and on the page 4, in the front panel section, there is a picture with the scope in what looks like a data logger that I wish, I bought the scope but I cannot find this function.

Please, let me know what can be done in future revisions of the firmware.

Best regards,

I also would like to add a vote to weight in favor of some improvements to this device, specially:

- Hide menu on second press of button [Menu]
- I agree that it is more intuitive and make more sense to use Up-Down keys to change volts/div settings and left-right to change the time base, but then you would have to use other combination of buttons to move the trace level or the vertical trigger on the screen, so I understand the choises made by Hantek.
- Add a few more options to the "measure" menu, at least the ability to get RMS and peak-to-peak values.
- FFT could be useful, but I don't think the hardware is capable of handle the calculations in a way to make it usable, so I wouldn't bother. The PC software is also buggy and sluggish, so if you really need FFT it's better look else where.
- The PC software can log the multimeter data, but it is very basic and you can't chose time interval nor stop the capture (software bug)
[attach]3037[/attach]

- And my main request: please, please, please open source the software or at least release the comunication protocol documentation so people can improve the PC software or write an alternative.The software provided is very limited, what is a shame since the hardware is not bad (for its price range) and this device could be a lot more interesting with a better software support.




Author: wolfallein    Time: 2019-8-3 06:37
I totally agree with you OASJ2YSeeEhBQo1,

On top of the list of wishes:

- open the communication for the user to develop own software.

I really think that this can be done. The PC software comes with some DLL that the oscilloscope probably uses for communication, and this oscilloscope probably has some similarities with the USB oscilloscopes line that comes with SDK. I think that they don't really need to open the code, they just need to document how to use the DLL.
If we have access to it we could develop custom programs to make better data logger, FFT, etc... Hantek could use it in their favor as we would develop it for free, and I would share my code if someone is interested. Everybody wins, Hantek wins because we help them to develop the software, the user wins because we can adapt to our needs, the community wins because we could share the codes. This would be a big selling point of this oscilloscope for future buyers.

I also agree with:

- Hiding the menu
- Add more options to the measurements

About the FFT, I just like to have a quick look in some frequency components of my signal sometimes (even if it is very small), nothing complex, a rough curve would be ok for me. Of course, if I want to go deeper I have to look for a spectrum analyzer instead.

Thanks to all the developers who created such a good and portable oscilloscope! I bought it recently. I disassembled it, and was delighted with the circuitry! I use and rejoice. I look forward to your continued software support. If anything is needed, I am ready to redo the circuit, install the cd card, wi-fi module, or any other components, write to the firmware controller and test the performance. I am a radio mechanic engineer by profession, I have been working for 17 years. A little knowledge is available.

You didn't understand me about Up-Down keys.
I am speaking not about changing UpDown to LeftRight.
I am about exchanging Left and Right in voltage mode.
Also exchanging Up and Down in time mode.

In all normal oscilloscopes V/div and T/div are inverted for more intuitive using, but in this in not!

Я не думаю, что это станет возможным, особенно не в ближайшей перспективе. Судя по глюкам и ошибкам в прошивках за последние пол года, им уже катастрофически не хватает оперативы, динамические массивы налазят друг на друга... Тут нужно сначала оптимизировать и исправить то, что уже есть... Но похоже им впадло этим заниматься. Может причина в том, что они хотели запихнуть туда всего и побольше, а в итоге ничего толком не работает... Вот нафиг там этот глюкавый мультиметр нужен? А с компом соединение для чего, если даже нет возможности передать сохраненную осциллограмму? Гальванической развязки с USB то нет! А вообще, с таким подходом надо было ставить не STM32F103, а STM32407, тогда может уже можно было релиз рабочий выпустить. Повышенная производительность и увеличение памяти в некоторой степени компенсирует рукожопость программистов.

In X-Y mode, is there some way to enable "vector" mode? All I get are "dots", which is almost unusable in my application. I tried using the PC software and it too only does "dots" when in X-Y mode. It would be GREAT if X-Y mode did vectors.

When using the Cursor in Time mode, it would be helpful if the unit could toggled between time-difference and frequency (1/time) in the "Increment" result.  Maybe pressing F3 could toggle between time and frequency.  It would avoid having to do the math off the device to calculate a frequency with the cursor.

经过几天的琢磨使用2D72，我个人感觉是这样的，总体还可以，必定只是个几百块钱的东西（还没有一块好万用表贵）。它是以示波器为主，信号发生器和万用表作为附带综合在一起的，我一直在用汉泰产品，之前使用的是汉泰DSO1202B产品，感觉不错，就是个头有点大，拿着不方便，关键是没有信号源，所以再用汉泰2D72上手就特别快。首先谈一谈示波器，总体上手还是很容易，由于功能多，所以使用了很多综合键，出现一键多用，让人有点手慌脚乱，时不时记不住，会错按。它只能出现四组最常规的数值，电压最大值、最小值、频率、时长（时间）。有这几组可以推算出其它数值，如峰峰值就是最大值+最小值，如平均值就是（最大值+最小值）/2，作为维修有这些参数也足够用的了。本信号有2V输出，超过半导体通断门电压。信号发生器一般作为测试三极管和场管通断，向基极或控极提供振荡信号，或向设备提供信号也足够了，一般使用有效信号都在10K以内，高的基本上用不到，更何况它能提供70MB呢，这个功能很好，否则我不会购这块表。万用表功能有点不尽人意，我拿它与胜利86E作比较，电阻、电压、电流都不错，数字都非常接近，就是速度比胜利86E慢不少。它的垃圾点是电容档，测试的慢还非常不准，一点可靠性都没有。我从P法级到N法再到U法对很多电容进行测试，得出结果是这样的，1U法以下的电容很准确，1U法--10U法少了30%左右，11U法到100U法，就彻底崩溃，胡乱给一个数字。100U法以上就不工作了，连胡乱数字也不给了。不过说明书上也标定最大就是能测到100U法。这是个不靠谱的电容表，也许我的汉泰2D72是一个个例，也许是我中奖了。本人江苏泗洪，本表从闲鱼上购得590块钱包邮到家的，从内心来说感觉很是不错。对得起这个钱。

Hello,

my name is Thorsten, I am from Germany, and I am new to this forum. ;)

Yesterday, I obtained my new 2D72 and so far, it works.

I would like to see some additional features for the DMM mode:

1. Possibility of measuring and displaying relative values.
2. Possibility of additionally displaying min and max values.
3. Possibility of fading out the connection scheme and instead fading in a bargraph.
4. Datalogger for logging and displaying measured values according to the picture shown within the quick guide.



Best regards,

Thorsten

Hello,

How can I transfer saved data from the oscilloscope to a PC, for example in the form of a .txt file? I need to analyze the data obtained outside.

Thanks for help
Best regards,

Zony

Hi again,

sometimes, the Hantek2xx2 software V.1.1.13 starts with a "read allset failed" message. How can I cope with this?

Anothter bug that I have recognized is that if I am hotplugging off the USB-A connector from my Surface Book 2, the software allways crashes.
