Title: Rigol DS1062CD advice please
Post by: Pier on May 27, 2023, 09:38:52 pm
Hello everyone,

Not sure if i should have posted this in the beginner section rather than here but here goes..
Since today i am the proud owner of a Rigol DS1062CD (https://www.tequipment.net/RigolDS1062CD.html) oscilloscope.
Kind of an impulsive buy, not even sure if it's good enough to do what i want to do with it. (diagnose & repair the ~20 YLOD PS3's i have gathering dust)
But i guess at one point or another an oscilloscope is the next logic step after a multimeter, right?

Paid 200EU for it, included was one probe (Rigol PVP2150 (https://rigolshop.eu/accessories/probe/pvp2150.html)) and powercable.
Unfortunately no active logic head but for now just an oscilloscope will do.
I had a look on ebay to compare prices but not many (https://picclick.com/RIGOL-DS1062C-DIGITAL-OSCILLOSCOPE-2-Channel-60-MHz-400MSa-s-193144528596.html) hits (https://picclick.com/ONE-DS1102CD-RIGOL-Fedex-DHL-Ship-MTA1MA-304520036385.html) for the DS1000C/CD/M/MD series, lots of DS1000E/D though.
Maybe someone can tell me if i paid too much / too little?

Haven't took it apart yet, just turned it on. (sorry Dave)

System info:

Did the calibration thing but it seemed already calibrated to me so i turned it a bit and then put it back where it was.  ;D
I've managed to find a manual and programming guide, but i'm having difficulties with finding firmware, PC drivers and software so if anyone could steer me in the right direction?
Rigol has some software on it's site but i don't think my OS is supported (Ultrascope DS1000CA gives runtime error when loaded on Win10) or if the current software supports my scope.
I would like to test it to see if it's still accurate/calibrated correctly but i have no idea how.. (buy a second oscilloscope with function generator? lol)
Found a cheap DIY function generator but that's only 1MHz.

Also, i'm wondering (main reason for my post here) if my model is able to be overclocked in software like the DS1000E and DS1000Z?
I haven't fully investigated this yet but it looks like yes(maybe) to me.
This thread about bricked scopes (https://www.eevblog.com/forum/blog/the-dark-side-of-the-rigol-hack-bricked-scope-how-to-fix-it/) has one user reporting having a DS1042C that had problems.
Something with how the DS1062C firmware update program works and on the flash chip the write enable and address pin where model data is written are not connected, but he managed to unbrick and after a firmware upgrade overclocked it eventually.
He mentions this webpage (http://codenaschen.de/tichyblog/index.php?action=blog&entry=17_Hacking%20Rigol%20DS1022C%20DS1042C%20DS1062C%20DS1102C), where is mention of a secret button combination for the DS1022C(D) that opens a menu which allows setting of the model up to 100MHz.
This site also warns that someone bricked his DS1062C trying this.  :-\

I guess it's maybe wise to first ask around a bit and have a look inside what flash chip i have and how it's connected.
After that i guess dump the flash somehow for backup if possible. (my Arduino / Teensy++ 2.0 should be able to do this as far as i can tell)

As a new one goes for 200EU i'm also wondering if there's an alternative for the active logic head?

Anyways, thanks for looking and any replies are welcome!

I've took the unit apart in the mean time, and broke the power button in the process..  |O
So if anyone's wondering, you're supposed to take the power button off first and then the housing.

Looks like the flash is:
Spansion S29GL032M90TAIR4 (https://datasheetspdf.com/pdf-file/1067559/SPANSION/S29GL032M/1)
TSOP-48, x8/x16, VCC=3.0-3.6V
Bottom boot sector device, bottom two address sectors protected when WP#/ACC=VIL

I didn't take the mainboard out because the usb port is soldered to the frame, so i didn't check how the flash pins are connected.

Re-assembled the unit and it still works, phew.
Then i tried the secret menu and it loaded, don't want to brick my scope so i didn't change any values.
