Hacking the Rigol DHO800/900 Scope

I ordered mine today from the Rigol Website here in the EU.  What do you guys want me to post here on the thread?

What did you order?

Firmware version when you get it.

My apologies, I ordered the 804 version for €399.00 delivered. I will indeed post the firmware etc.

Ordered my DHO804 Dec 5th, arrived today with firmware 00.01.02.

Has anyone tried using this it on a battery pack?
Which model, what capacity, what autonomy ?
Please share your experience

Thank you for this link, but this video is almost useless!
No information about the powerbank he is using.
We know that will works, but as in comments but not with all.
I am looking for user feedbacks on various models of powerbanks we can buy.

I tested my 804 with Lenovo Go USB-C Laptop Power Bank, it work with no issues.

I had a look to the description of this power bank, really good but pricy  USB-C output 65W, that is enough the scope need 48W (12V 4A).
On Aliexpress for now I haven’t found anything, all was PD3.0 but only 12V/3A even they claim 65W or even 100W but that is only bullshit marketing.

Where I can download DHO914 vendor.bin? Can't find in this topic (

I found this tool https://github.com/zelea2/rigol_vendor_bin and successfully changed model to DHO914 in my own vendor.bin

How did you use this tool, there is only poor description ?

it has builtin help

Code: [Select]

Rigol 'vendor.bin' encoder/decoder v0.6 - Zelea

At least the scope model (-M) must be supplied

./rigol_vendor_bin [options] [vendor_bin_file]
-M # set scope model
-n random serial number
-N # set serial number
-a random MAC address
-A # set MAC address
-o generate all option strings (uses 'Key.data')
-O # generate option string for feature #
-d debug switch

I'm not sure how much more information you need? He said in the video it was a 20,000mAH battery bank. What other specs do you need? Assuming the capacity is the same, any other USB-C PD power bank should operate very similarly.

As described in the user guide the power adaptator provide 12V 4A (48V), but if you have a look to usb-c PD3.0 powerbanks most of them provide only 12V / 3A so only 36W or even less.
The powerbank Lenovo Go used by t_i_t_o can provide 65W on the usb-c port

As discussed here several times (in the correct DHO800 thread), it is actually not correct that the scope uses 12V when operated on a USB PD adapter. It negotiates 15V, and hence 3A should be enough. The manual is outdated. It refers to the cheap adapter originally supplied by Rigol, which provided a fixed 12V output.

Could I ask that this discussion is kept out of the "Hacking" thread, since it has nothing to do with hacking?

The LO PSU is only rated 3A from 5-15vdc, but will allow 3.25A @ 20vdc
If the DHO wants to use 15vdc, it can only consume 45watt(max)

Making a comprehensive list will be tough.

This one is good value, widely available, and claims 15V 3A capability:

(on three ports simultaneously so I'm sure it will do it on one)

Disclaimer: Haven't tried it myself but I've got one on my Xmas list.

Start-up state file?

the 804, presumably 800 series, starts up with CH1 active and in Auto mode. Why it starts up this way is a bit confusing to me.
Is there a file to change (or menu setting) so it starts up with no channels active and in the STOP state?

[csuhi17]

This works fine for me.

Using USB-C.
it lasts about 5 hours when fully charged. and writes an average consumption of 38W.

I've received my DHO804 with 00.01.02 firmware from the factory.
I converted it to DHO914 via vendor.bin and then tried to activate 250Mhz bandwidth via license and it works without any offsets.
SelfCal was also successful

UPD: Also tried to change model to 924 in vendor.bin, no offset as well

Hmm, IIRC there are some posting saying the vendor.bin mod from 800 to 914 does not work for every aspect of the 800.
What changes exactly were made?

Only changed model in my original vendor.bin via tool from github

There is a strange thing on saye rigol. Both on a global and on a European level.

Fully updated new firmware, same version, no changes.

I installed AIDA64 and included is the report - this is for v 1.01 firmware.   AIDA seems to report Bluetooth but I have not seen any mention of built-in bluetooth device.  Hope somebody finds the report of value.

I am looking for the fan PWM interface - from /proc and /sys the following things come up:

/sys/bus/i2c/drivers/fan53555-regulator
/sys/bus/platform/devices/pwm_fan
/sys/devices/platform/pwm_fan
/sys/firmware/devicetree/base/pwm_fan

I am just starting to look at those locations, but if anybody has been able to locate the interface please let us know.
