>>Why go from 3032b to 3012b? Why not go 3052b, or, because you have a -b model, why not go 3062b?

Good question, but I did what this thread on the first comment said, and it went down instead of up... WTF???

PASSWORD PITBULL
MCONFIG TDS3054

and that was it... went down instead of up!!!!

try

PASSWORD PITBULL
MCONFIG TDS3054B

>>why not go 3062b?

hMMM... guess I forgot to put the B at the end... now it is a 3064B

Thank you very much!!!

DAMN it supposed to be 62 not 64... damn it... so damn dumb!!!

whatboy · « **Reply #128 on:** March 14, 2022, 07:45:41 pm »

there is no 62 so 52 it is!

No one posted here for a year - but... Is it possible to update with mentioned serial command and password:

TDS3014B / v3.26 to TDS3054. It is already updated with all possible options vie EEPROM.
If not - can it be upgraded to some higher model, or not?
Is there a possibility to brick the scope or destroy calibration by using commands used above?

Thanks in advance!

With your actual firmware You can jump of 3014 to 3054 or 64, only need calibrate DC offset ando ready. You can also Buy an used tds3fft stick and programing with all software unlocks for get all funcions, I had a TDS3014b that was converted to TDS3064b, finally I sold, only I have TDS3052B with all unlocks, 500 MHz, and floppy is emulated with USB converter for read & write USB sticks.

Raul, which USB converter did you use?

This it can works and adjusts well in the scope.

$547? Oh wait, that's Pesos, not US-Dollars. So yes, a very decent price. Thanks for the link.

Yes MXN, is amazon.com.mx, but comes of China, works fine, you can save configurations in USB stick, then load in oscilloscope, also you can get screenshots of display, if you found 1.44 MB version you can update the firmware too. This is 720 kB version.

alm · « **Reply #135 on:** January 20, 2023, 11:16:30 pm »

If you flash either drive with the FlashFloppy firmware, then both can act as 1.44 MB drives and have a bunch of extra features.

Can anyone confirm that this has worked on a TDS2002C?
I just picked up a NIB TDS2002C and wanted to give this upgrade a try.
I suspect that it will and that my challenges are related to getting the software properly set up, but before I keep beating my head on a wall, I want to confirm that I'm not attempting the impossible.

ghopper · « **Reply #137 on:** February 22, 2023, 10:57:47 pm »

The firmware version is 24.26. I'm wondering if I need to downgrade the fw version and if so, to what?
After getting everything talking via usb (still getting an occasional I/O error), I used Talker Listener to send the *IDN? command to confirm the communication was working. After that, I wrote the command PASSWORD PITBULL, and then wrote MODEL TDS2022C.
Then I went back and used Instrument Manager to ID the scope.
No luck. For giggles I also tried the MCONFIG TDS2022C command. No joy there either.

I noted that with the 3xxx scopes the version of the firmware mattered. I'm wondering if that might be the case here.

If that is the case, I'm hoping someone can suggest both a source for the older version(s) of fw (the TEK website only has 24.26), and how far I need to roll it back.

Thanks for any help.

Having more success, but not all the way there yet.
It turns out that the firmware version is fine, but the passwords was wrong. At the beginning of the thread, the password indicated was "PITBULL", but that never worked for me. What did work is "INTEKRITY".

So, now I'm seeing the model as a TDS2022C, until I power cycle it. Then it's back to a TDS2002C.

I noted that rfdes had made a post saying "I forgot to mention that for the TDS1000/2000 and TDS200 instruments, the BW update will not be saved unless a full calibration adjustment is performed before the unit is shutdown." I assume this includes the TDS1000/2000C series as well.

Since I don't want to screw anything up because I misunderstood something (meaning I think I know what is meant, but turns out something entirely different was what was meant...) I looked in both the user manual and the service manual for the 2000C series for the term "calibration adjustment" but never found those terms together. So I'm hoping someone can explain what actually is meant by that phrase.

alm · « **Reply #139 on:** February 23, 2023, 04:58:17 pm »

Calibration adjustment is described in chapter 5 in the service manual under "adjustment procedure".

ghopper · « **Reply #140 on:** February 23, 2023, 06:42:42 pm »

Thanks for replying.
I'm assuming you're saying that he was referring to the Factory Calibration. Versus the Self Calibration that is also described in the manuals?

alm · « **Reply #141 on:** February 23, 2023, 08:05:57 pm »

I'd try the self-cal first if you haven't already, because that's trivial. The adjustment procedure as described in the service manual requires specialized equipment that you probably won't have access to.

ghopper · « **Reply #142 on:** February 23, 2023, 09:51:55 pm »

Thanks for following up alm!
I did try the self cal and what that does is knock the scope back to being a TDS2002C. :-(

I have done analog scope calibration (verifications... since the two times I went through the process, the scopes were within spec) so I think I have all of the equipment I need. I need to double check for a couple of things, but I have a leveled sine wave generator, square wave generator, and a good quality variable power supply so I think I'm GTG. Well, maybe not exactly.

The one thing I don't think I have is enough identical, BNC terminated, short (the manual says 10"), coax cables to interconnect things. I have plenty of random length BNC cables, but IIRC only pairs that are the same lengths. It looks like I only need 3 for a 2 channel scope, but that might be one more than I have. I assume that if I build 3 from the same parts, that should be just fine.

Interesting that the service manual copy you linked to is different than the one I have been referring to: https://download.tek.com/manual/TDS2000C-TDS1000C-EDU-Service-077044602_RevA.pdf

The one I was looking at included a rather complicated "Performance Verification" section from pages 27-39, before the (I assume) Factory Calibration (aggravatingly enough called Adjustment Procedure, not factory calibration) section (pages 41- 48) which is identical to the procedure in the manual you linked to (pages 5-1 through 5-9).

Thanks for the pointers in the right direction!!! Please let me know where I'm going astray.

Cheers,
Grant

Also work with 26 pin version?

alm · « **Reply #144 on:** February 24, 2023, 09:56:16 am »

Yes, FlashFloppy works with the 26 pin Gotek drive that fits these scopes: https://github.com/keirf/FlashFloppy/issues/155.

Thank you to Alm (and Håkan on the Tek forum) for helpful information as well as Dennis Tillman, W7pf for his help.

To close the loop on this question, yes it's entirely possible and not particularly difficult to upgrade a TDS20xxC series.

It takes three pieces/resources/steps.

First is to install the communication software (BOTH packages are required) from Tek, including Openchoice Desktop and TEKVISA.

Then establish communication with the scope (USB cable) via the software and change the model. First, I read the identity of the scope using the "*IDN?" command via QUERY. Second I sent the PASSWord command and the password INTEKRITY via WRITE (not QUERY). Older models used PITBULL, but newer models (like the TDS20xxC models) use the newer password. Then I sent the MODEL command and the new model number "TDS2022C" via WRITE (not QUERY). Lastly I read the identity of the scope using the "*IDN?" command via QUERY again to see that the model had been changed.

The third step is to run a full factory calibration via the "Adjustment Procedure" instructions via the Service Manual. If the calibration procedure completes successfully, it will write everything back to storage and the model number change will persist past the power-down of the scope. The Self Calibration will NOT write the model number change to storage and it will be lost after power-down.

It's not hard to do, but it takes certain resources. The calibration is the most tedious step and takes a stable power supply that can be adjusted down to 0.015VDC, a leveled sine wave generator, and a square wave generator, as well as a couple of identical coax jumpers, a T and a 50 ohm passthrough terminator. Check the service manual for the specifics. With all the messing around, it took around 2-2.5 hours to get this all done.

Cheers,
Grant

I flashed the floppy emulator with "flashfloppy", now can emulate with *.img file an 1.44 MB HD floppy disk, also I can to put firmware, downgrade and upgrade it. Is not necessary depress buttons for USB save files like in "original floppy emulator firmware".
Only found a disvantage is you need 7zp for get files from image, is not saved in root directory like before. But 1.44 MB,write and read without press botton and firmware upgrade without obsolete and unestable diskfloppy is a great advantaje.

This article has necesary information for doing it.

Note: You need open the emulator for see if is STM32, the flashing procedure change but is documented in flashfloppy wiki.

Anything you buy right now will be AT32F415 or AT32F435, unless you find some very old (pre mid-2020) stock. I haven't seen any slim drives with AT32F435 yet. There is also the HxC firmware for these drives which does support storing files in a directory instead of inside a floppy image, but it costs €10 and I haven't been able to get this firmware to work with my slim Gotek in my Lecroy WaveRunner2 scope yet (works fine with FlashFloppy). When I have some time I should post on their forum to see if anyone has a solution to get their firmware working, because I would like the storing files in a directory feature.

I bought in amazon on 2021, I flashed with DfuSe.

Bonjour,

J'ai un TDS 3024 4x300mhz
Avec son lecteur de disquettes d'origine qui fonctionne très bien.
Je vous entends parler de mise à jour !?
Ça m'apporterait une meilleur bande passante ? Et la fonction FFT par hasard?
Il y a besoin de remplacer des pièces comme sur le TDS 220 ?

Merci
