Rigol's New DHO800 Oscilloscope unbox & teardown

[akkk44]

I tried the new image and it works as intended, Thanks a lot!

A little disappointing - you'd think that with Android the keyboard support would come more or less for free.
Even so that wouldn't be a deal killer for me.

Confirmed, keyboard is detected and a few keys are accepted, but you can't enter numbers into entry boxes for example. Basically it's not implemented.

Thanks a lot, I will try it later, no worries whatsoever!

Very much looking forward to the final result

Probably the UI toolkit they used.

I agree that "vertical" isn't the ideal angle for typing on touch screens. I use a stylus when I work with my touch laptop.

then we need to put in a request for rigol to improve the keyboard support in their android app... and check it's not any better on the higher models (hdo1000 & hdo4000 series)

I'll bet a million Ohms that it's exactly the same.

[RAPo]

well there must be someone on this forum who has such an oscilloscope ....

[dreamcat4]

1 million waveforms per second = Keysight DSOX3024A

but how about: 1Mhz
Because my current scope is only 40khz effective bandwidth

Well, success!

Thanks to @hubertyoung's fw 1.14 image I was able to convert my DHO804 to DHO924 with no vertical offset issue. There was a vertical offset issue for some of the channels when I replace the vendor file but this time I performed the extended cal and the offset issue went away. None of the channels have any offset issues for all the voltage ranges.

Having this on screen would really annoy me:

Did you got a new SD card to write the new image or you wrote over the existing one ?
What SW version was before as mine seems to be 1.0
Are there any other advantages to use the DHO924 firmware other than the increase bandwidth? (likely requiring different probes to take advantage off).
Not sure if there is extra sampling memory or just allows more in 4 channel mode.
Did you notice the strong plastic smell. I left mine outside since yesterday I need to check if there is any improvement.

Can someone link to the image file please? Thanks.
Is it really just as easy as overwriting the SD card with a DHO900 image and then running the 10min calibration?

Here is the DHO804 FW1.14 image (Thanks to @hubertyoung) with the DHO924 vendor file preloaded. Extract using 7zip then flash using HDD Raw Copy Tool (compressed image). If there is an vertical offset then use self cal or extended self cal.

Hi,

• This is what I've done:
  1. Run the Win32 Disk Imager
  2. Backup the SD
  3. Flash the SD with the image from the link
  4. Run the claibartation (offset gone) - device identifies as DHO804
  5. Connect the scope to ethernet
  6  Run adb:
      6.1 adb devices
      6.2 adb connect 192.xxx.x.xxx:55555
      6.3 "adb pull /rigol/data/vendor.bin"
      6.4 backup the generated vendor bin file from the adb folder to a new location
      6.5 copy in the adb folder the  DHO924 vendor.bin file
      6.6 "adb push vendor.bin /rigol/data"

I still wonder if it's possible to do it without disassemble.
I'm gonna to keep the warranty.

Cracking vulnerable stickers is much easier than using software. You guessed it right. This 924 bin file was the first batch I purchased. I posted the disassembly pictures at the beginning of the forum. I disassembled it losslessly through technical means. Unfortunately, I did not directly back up the 924 image file. Finally, I backed up the bin through the adb command. I chose to return it. I hope rigol doesn't see this comment.

Thank you very much for improving the download content, which is very friendly to newcomers.

I'm curious, if I directly use someone else's 924s image to directly overwrite the SD card, it should be cracked. It's just that I don't have a 924s oscilloscope. If anyone has it, please share it (the SN will be exposed).

Was shooting the review video and this happened, WTF!
EDIT:  It's NOT the DHO800 at fault! Follow-up video shot on the 2nd channel.

 
David! Possibly on the first channel there is poor soldering of the printed circuit board with the BNC  connector

I've seen very flaky stuff like that before. I'd bet the BNC connectors or the cable crimping. You can't see the quality of work inside the adapters or the crimps. I've had to throw out junk and replace with new. I've found many cheap adapters that aren't made to exacting specs (I know shocking) and have very weird connection problems.

Having this on screen would really annoy me:

You should get used to this. I think all software currently has been cracked. As for parameter comparison, which requires help from others, volunteers will then need to compare the 924s to complete the hardware IC and restore it to the real 924s.

I'm very sure it's possible to hack just the bandwidth without those extra features.

Right now what they're doing is copying the entire 924 firmware so they get those artifacts.

[Fungus]

We need a copy of as many  different vendor.bin files as possible to compare them and see how individual features are enabled.
