Unlocking Siglent SDS1104X-E, step by step

(1/62) > >>

Fungus:
This is an unofficial guide on how to unlock 200Mhz bandwidth on SDS1104X-E oscilloscopes, effectively turning them into SDS1204X-Es.

The steps are: (courtesy of user SMB74)


--- Quote from: SMB784 on August 31, 2018, 08:37:10 pm ---Here was my process

1.) Format a USB flash drive to FAT32

2.) Load the flash drive with the SDS1004X-E Firmware (4-Channel Model) - 6.1.25R2 (Release Date 06.29.18) by downloading it from the Siglent website and unzipping it onto the flashdrive.

3.) Once the file is loaded, install the firmware onto the oscilloscope by following the instructions in the PDF included in the firmware zip file.  Verify the correct firmware version is installed using the menus within the Utility button, and take note of the model number (should read SDS1104X-E)

4.) Once the firmware has been installed on the scope, reformat the flash drive to FAT32 and unzip the SDS1004X-E Operating System-V1 (Only For 4-Channel ) (Release Date 06.26.18) after downloading it from the Siglent website.

5.) Install the software update onto the oscilloscope by following the instructions in the PDF included in the firmware zip file.  Reboot the scope and verify the correct software version is installed using the menus within the Utility button.

6.) Download the custom operating system file that possesses the known telnet password.  Unzip it onto a USB drive and install it just as you installed the stock software file from the Siglent website.  NOTE: Some computers do not correctly load the software file onto the USB drive, thus preventing the scope from updating from the stock software to the custom software.  I have experienced this problem personally.  If this occurs, try loading it onto the USB from a different computer.  I had success using a Raspberry Pi to load the custom software onto the USB.

7.) After installing the custom software, plug the oscilloscope into your router with an ethernet cable, and telnet into the scope on port 23. MOst operating systems have a built-in telnet client, try opening a command shell and type "telnet". If that doesn't work then you may have to install a third party client like "PuTTY".

User: root
Password: eevblog

8.) Once in the scope via telnet, execute the following commands:

mount -o remount,rw ubi2_0 /usr/bin/siglent/firmdata0
cd /usr/bin/siglent/firmdata0
mv bandwidth.txt bandwidth.bak
sync

9.) Reboot the scope (eg. by typing "shutdown -r now") and verify that the model number displayed in the Utility button menus has been updated to show an SDS1204X-E

Now the scope should have 200MHz bandwidth.

EDIT: Thanks ian.ameline for the link to a download source for the custom software. I have updated step 6 with this information.

plus a video will be great.


start from here from what i observe.

Ian posted the most concise instructions for the bandwidth upgrade in that thread:

1. Update with the OS update with the known root password.

2. telnet to the scope, and log in as root.

3. Execute these commands:
   mount -o remount,rw ubi2_0 /usr/bin/siglent/firmdata0
   cd /usr/bin/siglent/firmdata0
   mv bandwidth.txt bandwidth.bak

4. Reboot

I don't think there has been a definitive consensus on unlocking the other options without option codes?

Yep like that and similar for SSA too.(mentioned in SSA hack thread)
There are other/better ways too.  :-X

a) Which you get.... where?
b) How do you install it?

a) Telnet port #?

4. Reboot

Is that definitively all it takes? I've read a few places that there's some weird aliasing at high frequencies that isn't in the real 200Mhz version of the 'scope, that maybe something else needs tweaking.

To me it seems weird that you'd hide the bandwidth.txt file instead of modifying it (if I were a Siglent firmware writer I'd default to low bandwidth when the file is missing)

You mean the "software" part of the AWG, MSO and WiFi options?
