Hantek DSO2C10, DSO2C15, DSO2D10, DSO2D15 (DSO2000 series): firmware updates and best use practices :-BROKE If you are considering buying one of these Hantek DSOs, or have just bought one, you might find the information below useful. Note that all these models are based on exactly the same mainboard. The DSO2D1x models populate the mainboard with components for an Arbitrary Waveform Generator (a rather basic 12-bit function generator with limited functionality), the DSO2C1x models don't. And the DSO2x15 are good to 150MHz, while the DSO2x10 models are software limited to 100MHz. The DSO2000 Series User Manual can be found here: http://www.hantek.com/uploadpic/hantek/files/20210409/DSO2000%20Series%20Digital%20Storage%20Oscilloscope%20User%20Manual.pdf This thread is a restart of the previous https://www.eevblog.com/forum/testgear/new-hantek-dso2x1x-models/ thread, which got too confusing for people searching for essential information on firmware updates and general use hints and tips for these "value" Hantek DSOs. :-// Note that if you are specifically interested in hacking your Hantek DSO2x1x, you should look into this thread: https://www.eevblog.com/forum/testgear/hacking-the-dso2x1x/ See the next post for firmware update recommendations, the third post for links to reviews, and the fourth post for bugs, limitations and other issues. Also see DavidAlfa's post below for tons of relevant information which he has collected through extensive research into his DSO2D15. |

WARNING! Before you update the firmware on your Hantek DSO2x1x, you may want to consider the following: 1. Some firmware updates have been shown to cause various annoying problems and decrease the stability of the DSO internal software. 2. The firmware update process can for various reasons fail, leaving your DSO in an unusable state (i.e. "bricked"). 3. In principle, it is always possible to "unbrick" a "bricked" Hantek DSO2x1x, but it's better not to "brick" it in the first place. ;) 4. Before you get started on any firmware update, take a picture of your DSO "system information" screen. 5. Last but not least, remember the old adage: "If it breaks, you get to keep the pieces." ??? This is the firmware update procedure described in the Hantek DSO2000 series User Manual: --- Quote ---2.14.1. Update Firmware This series of oscilloscope can upgrade the software by the USB flash disc, which needs about 5 minutes. The firmware is upgraded by the following steps: 1. Plug the USB flash disc in which a firmware program is saved in USB Host interface on the front panel of the oscilloscope. 2. Press [Utility] button to skip to the Utility menu. 3. Press Update -> Update Firmware softkey. 4. Select the file and press Multifunctional Knob to confirm. Then press Start updating softkey to update the firmware. 5. Reboot the machine after finishing upgrading, and the software version is upgraded. The oscilloscope should be self-corrected once after upgrading. --- End quote --- At present there are two repositories for Hantek DSO2000 series firmware updates: 1. The Hantek official website at hantek.com: http://hantek.com/DownLoad 2. DavidAlfa's GDrive folder: https://tinyurl.com/ytteeyj7 Which is the recommended firmware update? Unfortunately the answer is "it depends..." As of June 2021, there is no single firmware update that will reportedly work perfectly on all Hantek DSO2000 Series models. List here the firmware updates available and recommendations. Explain the "fool proof" firmware update process. Explain the "fool proof" unbricking process. |

This is a list of known bugs, limitations and other issues. Bugs The following is a list of verified known bugs: * The DSO will lock up when switching ranges too fast! Known bug and Hantek has been notified. Limitations Hantek have cut quite a few corners to lower the cost of the DSO2000 Series scopes. So there are some limitations, some obvious, some not. * The DSO2000 series are shipped by Hantek with a single probe! Yes, that's right. You have to buy a second probe separately. * The embedded ARM CPU does not have hardware floating point. Indeed, but that should not change much in terms of general operation of these DSO. * The function generator in the DSO2D1x models performs poorly. Again, that's correct, it has limited performance and functionality. If you need a function generator with better specs, use an external one. Other issues * Hantek have been slow in coming up with firmware updates that fix well known problems. Patience! Hopefully as the number of units sold increases, they will accelerate the firmware updates. |

Various bits and pieces of information that don't fall in other categories 1. My DSO2x1x came with just one probe, even though it's a dual-channel DSO! Hantek is delivering all these DSO's with just a single probe, so you'll want to order an extra probe when you purchase any of the DSO2000 Series models. Note that any standard oscilloscope probe will work, but you'll probably want to buy a Hantek PP-150 probe to match the one that came with your DSO2x1x. 2. Where is the FEL button located? (refer to the hacking thread to know what the FEL button does; it is not needed in normal operation) |
