what equipment do you need to calibrate the oscilloscope when the above resistors have been changed. What is the procedure. Would the normal oscilloscope push button calibration do the job? I don't know much about what the calibration is other than you only have the power cable connected to calibrate.
Question: For compensation you refer to 3 components. Do you have to change all 3 components or you only have to adjust the trim capacitor?
I have finally ordered a Tekway DST1102B 100MHz oscilloscope from Pioneer.

I will let you all know how this purchase go, I don't anticipate any problems as Pioneer has at this time a 100% positive feedback, refer to the above link .
My God, I had visited this Aliexpress website . You can see how no care is made for packaging and handle electronics accessories like probes.
If people only concentrate the price, well why not proposing everything like a kit with components, case, bill of materials and serigraphy masks for each country!
Then people arrange by themselves (soldering, cleaning, testing) and everything is ok. Ok, men, we will give you a 300.00 EUR oscilloscope kit, and wish you good luck ! Just this policy is not ours: we change bad boxes, change power cord with 2.50m (Hantek/tekway is 1.50m, a bit short for convenience), change CD small pocket when this one is damaged. Electronics should be handled with care, not like trash...

Hi Pascal,
Question: do you give a three year warranty if we change the resistors and firmware in the oscilloscope?
Hi Pascal,
Question: do you give a three year warranty if we change the resistors and firmware in the oscilloscope?
hehe, RFman, knowing that a custom might play with the DSO internals is one thing, allowing up front is a different thing.
I would never allow it up front, therefore all my customers got a simple question "shall i do it for you?",
if yes i did it and i'm responsible for potential warranty issues, if no then i placed "tags" in NAND, PCB and input channels cover.
But well, the question is not what i think and allow, the question is what Pascal does.
I scanned the Chinese panel and replaced the characters with English.
I haven't tried it on for size yet, but it looks close!

Hi guys,
I heard that recently all the new DST 1062B from the traders have been with upgraded firmware version 2.06.3. The new version has hack-prevention which prevents illegal firmware update as we did for ver 2.06.2.
Although firmware upgrading with hacked fimware image by USB is not allowed anymore, , I guess by JTAG we still can backup the image and then change to hacked version, if CPLD and FPGA design are not changed from v2.06.2 to v2.06.3. Has anyone tried and confirmed this? Also kindly correct me if I'm wrong.
Thanks!
The Photoshop file is about 50MB if you want to play with it PM me your email address and I'll send it to you.

if you would spend 10mins to read this thread you will see that:
- yes we know it
- yes it works still over UART
- yes it can work over USB if you read carefully what i wrote
I dont think so, there are 24 pages with 350 answers,
it took me one afternoon to read everything,
result was: I know less than before!
