Siglent SDG2042X Hack door closed

[Martin72]

Maybe we should make a script for the sdg only (just remove all things except 120Mhz bandwith (and 40Mhz for selfcontrol)) to avoid misunderstandment.

Don't go that way as there's plenty of garbage around already. Those that can't solve that by themselves don't deserve to "hack" the thing.

Indeed. I applied this hack a month ago or so, it is so stupid simple, nothing will help to make this easier.

Thanks for the "Guide for Dummies" @ghulands, I can confirm that an "improved" SDG2042X does indeed produce a clean 120MHz signal (checked on a 500MHz scope).  Folks doing this with generators running newer firmware should note that the hack requires downgrading the firmware to 17R5 and then back up to 23R8 and then 37R6 in steps.  It's also worth noting that new/larger USB flash drives don't seem to work; I had to dig up an old 128MB flash stick.

Perhaps the hardest thing about the hack these days is finding the actual instructions because the threads have become so long (68 pages)!  The link of interest is here: https://www.eevblog.com/forum/testgear/the-siglent-sdg2042x-thread/msg928681/#msg928681

Did you miss the much more recent process and just use one from 2016 ?

Much much safer than mucking with OS code.

Larger flash drives work fine, but not all brands and types are equal. I use SanDisk 32GB Ultra Fit USB 3.1 Flash Drives in all my Siglent gear with no issues. Firmware upgrades run without trouble too.

Yes, somehow that method sticks... No idea why you want to do that. Maybe because of the title of this thread? Maybe you need port 5024 (not a standard ip port) and telnet (not ssh)? No idea. Haven't tried, but I think the telnet method is even reversible.

I did update the firmware to whatever was the latest. But the update had no relation with the telnet hack. I repartitioned the USB, so there was only one partition on it. Sometimes there are weird partitions on the stick from factory and/or when used to boot a Raspberry Pi. Also storing files on the USB stick works fine after partitioning it. But again, only for updating and storing. Normal use.

I just get the unit today.
The keygen method still working

Too bad these units have the power connector on the back. Otherwise you could hack them before even fully unpacking. 

ebastler, who still enjoys his "upgraded" SDG2042X.
(Except for the slightly sluggish touch screen and rubber buttons...)

 Minki misnamed his licence upgrade as a "hacking" exercise which carries no risk of turning his brand new SDG 2042X into a "brick", hence his "plunging straight into 'upgrading it'" straight out of the box.

 The worst that can happen when using the keygen is that it simply rejects invalid licence keys with no harm done.  I guess he must have thoroughly researched the topic perhaps even to the point of having the keygen script ready to roll the minute he'd unpacked and checked it out.

Just want to share the state :'( :'(
I am happy with SDG2042X easy to  'upgrading it' and stick in SDS6000A upgrading :'( :'( :'( :'( :'(

Another one who made it.

Instructions are still valid.     
HW 02-02-00-40-00
SW 2.01.01.35R3B2

The online python worked fine:
https://www.programiz.com/python-programming/online-compiler/

Thx to all of you involved in exploring the device. 

Without reading the full thread: 
Is the -40- in the HW version info a hint, that there is some bandwidth specific HW involved and that the 120 HW might be different?   
Edit: reading some of the thread: NO, the -40- is some kind of HW version counter, there are -35- or -46- devices in this thread.   
But nevertheless: Any HW or performance differences known?

Best to stick to official BW licenses to ensure performance matches spec. 
40, 80 or 120 MHz.

HW 06-00-00-46-00
Product type : SDG2042X

software unlock/upgrade script did not work for me. None of the options matched code in the device. That is sad, might be returning it to Amazon.

Then you must be doing something wrong.

[alexian79]

Thank you,
it sure can be I am doing something wrong, for the script is product name should be as on screenshot? should SCOPEID be padded with something to certain length?

The model is wrong. Should be like SDG2000X.

[alexian79]

thank you TV84, with correct SCOPEID it now matches 40M option from generator.
HW 06-00-00-46-00 works fine.

[backyard_cnc]

Worked as promised! Easy peasy as long as you pay close attention to the details!  Tnx so much!

 I’m  loving this forum and the very affordable Siglent test equipment, I’ve got both my SDS1104X-E and SDG2042x “enhanced” and I’m now looking very strongly at ordering up the Siglent SSA3021X plus as soon as the toy budget bounces back.

FYI: The Python script doesn't run under Python 3.12.1

I had to specifically specify Python 3.11.
(using Fedora Linux)

Code: [Select]

😼 python3.11 ./SiglentKeygen.py
INFO: CHECK YOUR GENERATED KEY BEFOR ENTER A NEW ONE !!!

You get your bandwidth key by running "MCBD?" at the SCIP prompt

Compare your key with the generated key
INFO: IT HAVE TO BE SAME !!!




--------------------------------
Here are the bandwidth codes
Enter these codes over SCIP prompt

Thanks for sharing, I managed to crack the scope from SDS2104X Plus to SDS2354X Plus, also I have added the otpions like FLX,I2S, etc... But the script has lacking serials for these options


SDS_2000XP_SENT
SDS_2000XP_Manch
SDS_2000XP_4BW05

What string should I use for it in the script?

bwopt = ('25M', '40M', '50M', '60M', '70M', '100M', '120M','150M', '200M', '250M', '300M', '350M', '500M', '750M', '1000M', 'MAX', 'AWG', 'WIFI', 'MSO', 'FLX', 'CFD', 'I2S', '1553', 'PWA')

[Martin72]

Wrong thread here...

[ali_asadzadeh]

already found them

'MANC', 'SENT', '500M'
