Thanks MarkL for your reply.

So this means it is not a dc input => it is not very valuable

Probably not too valuable for bench use, but I could see it being useful for someone who did a lot work in the field.

You could use the battery pack connector as a "DC In" if you wanted to use the scope with a DC supply or external battery:

Hello all.
I can confirm that BW upgrade worked on my TPS2014. But only if a full calibration is done after entering the password and model trough the serial interface. The BW limit is now gone up to 200Mhz. So thanks to all who made this upgrade possible.

Perhaps the ARMDEMO command found in newer models will work on these too?

Code: [Select]

battery info:

DQ - signal from bq2050 fuel gauge...

I sent these instructions with OpenChoice Talker Listener vie Ethernet to my TDS3032C:

PASSWord INTEKRITY
SETMODELID 5
HWAccountant:ACQBandwidth 500

Nothing happened.

Is this format correct?

TDS3014B upgraded to TDS3064B and all applications activated. Thank you everyone!

I've got a TDS3012, and one channel isn't functioning.... However I'd like to explore using this bandwidth hack.

However, I don't have a B or C model, and don't have any I/O modules like a GPIB or Ethernet module.

Is there somewhere that I can find a serial header to issue the commands?

Just bought a TDS3014B and can also confirm a successful upgrade to a TDS3064B.

I have access to an old HP RF generator so I tried to check the BW extension. The test wasn't too accurate as I don't have a leveled sine generator. I could measure a HF rolloff at 490MHz (-3dB) using coax cable and 50ohm termination. Using a P6139B probe might push the rolloff even lower. So I presume the upgrade is more a TDS3044B which is still more than enough for me.

The scope has a battery pack installed and I can confirm that the 15V DC power output works with no AC power line connected. This is a nice feature as you can test small prototypes in the field.

LOL !! Love the "modules" !!
Next : an upgraded model & bw sticker on the front...

So glad I found this thread! I just bought a TDS3012B-NV (I think I read this was labeled for the US Navy.)
I had to fix a malfunctioning floppy door which took me about 30 minutes.

Installed version 3.39, and got TEKVISA loaded onto an older Windows 7 laptop.
Connected the scope via ethernet to my network, watched a couple shot youtube videos on TEKVISA and upgraded my scope with this:

PASSWORD PITBULL
MCONFIG TDS3052B

It temporarily messed up the calibration (offsets were all wacky), but it's fine now after cal and it now samples at 5GS/s! Checking the rise time with a Picosecond step generator, it's reporting a faster than my Agilent DSO6034A. Thanks to everyone who posted info here.

josef · « **Reply #60 on:** September 27, 2019, 01:44:51 pm »

Hi,

I connected with scope via ethernet. The command *IDN? work correctly, but comands PASSWORD and MCONFIG doesn't work. Especially I don't know whether I use correct syntax of commands.

Thank you

tonykara · « **Reply #61 on:** September 27, 2019, 10:38:39 pm »

josef, what scope do you have? It worked for me. The scope won't show any difference until you power cycle.

james_s · « **Reply #62 on:** October 21, 2019, 11:31:51 pm »

For those who have a TDS3000 without ethernet or the comm module, I have reverse engineered the RS232 portion of the module which someone has used with success. All you need to do is buy the mating connector for around $10 and wire up a 3.3V serial level shifter or USB to LVTTL serial module and you're good to go.

Hello mate. I have the 3014b and would like to upgrade it to the 3064b. I have tekvisa and have it communicating with the scope through Ethernet but not sure where i go from there and how to know if it has worked. Is there anyway you could walk me through it somehow.
Its on version 3.15
Your help would be appreciated.

james_s · « **Reply #64 on:** October 26, 2019, 11:53:36 pm »

Did you read the rest of this thread? It's only 3 pages and it contains all the information you need. You don't even need Tekvisa, there's a console in the web page somewhere that you can use to send the commands:

First:
PASSWORD PITBULL

Then:
MCONFIG TDS3064

Then cycle the power and run the SPC routine from the normal calibration menu in the scope and you should be all set.

feret81 · « **Reply #65 on:** October 27, 2019, 06:45:39 am »

Yeah I'd been through it but some people are putting the password up and some not. And do I need to put the b on the end of 3064 or leave it out like you have. Thanks for the reply anyway.

james_s · « **Reply #66 on:** October 27, 2019, 05:40:28 pm »

I don't believe you put the b, but my scope is a plain old TDS3014 without a letter so it didn't apply to me.

You definitely need the password, just send the strings exactly as they are shown, you won't see any effect at the time but when you power cycle the scope it should come up with the new model. I don't think you can really screw this up, if you do it wrong it just won't change.

Hydron · « **Reply #67 on:** October 27, 2019, 05:52:40 pm »

Try setting it to TDS3054B as well as 3064 - the 600MHz option didn't seem to work when I tried it, but the 500MHz did, though I didn't do any mucking about with firmware etc to see if I could get a better result.

SMdude · « **Reply #68 on:** November 03, 2019, 08:15:51 am »

Thinking about getting one of these scopes as I want something decent that can be run from a battery and like the hackability so far.
Has anybody thought about updating the sample memory? I see it is only 10k in the TDS3000 series. High speed memory has become a lot faster, bigger and cheaper since these scopes were built.
It would probably require the firmware to be modified to get it to work. Just thought I would put it out there!

Cheers

Edit: Don't think it can be done, see

james_s · « **Reply #69 on:** November 03, 2019, 04:47:23 pm »

Yes lots of people have thought about it, it's not possible to do.

The optional batteries are also rare and crazy expensive. I'm a Tek fan but I'm not sure I could justify buying one of these for what they typically sell for.

SMdude · « **Reply #70 on:** November 04, 2019, 10:15:08 am »

For the battery pack, I would roll my own using li-po's and build in a suitable charger.

As for the price, I'll try and find a non working one for a reasonable price. Bit of a risk, but one has to be choosy of what problems it comes with. BTW James nice score on the one you got!

I would be open to other brands, but I don't want something that is clunky and slow or comes with inherent design problems. I have been using an old analog scope for years and really like the way it behaves. It has no bells or whistles! I have used various usb scopes and they just don't cut it.

The -B version of the Tek battery has a safety recall. Tek will replace it for free.

blackfin76 · « **Reply #72 on:** November 08, 2019, 06:41:21 pm »

I just pulled the hack on a TDS3012B and a TDS3034, both where a succes. For the TDS3034 I borrowed a TDS3EM ethernet module from work, they don't use it in the weekends. For some reason my Chrome browser wasn't able to display the web page, Firefox had no problem. Anyone else has issues with Chrome.
At first I made a mistake setting the TDS3012B to TDS3064B, it displayed the right version but on doing the SPC it failed and since there is no TDS3062B I had to downgrade to a 5 model.

Personally I love the TDS3000 series, it has been my daily driver for at least 15 years and it has helped me on many projects. It's very reliable in it's measurements even when running it for days and the responsiveness is almost like an analog oscilloscope (which I have much too many

). If you can pick one up for a nice price you won't regret it.

Bought quite a bunch of ‘dead’ packs (B and C), the problem was always (up to now) with the cells, have you ever encountered dead electronics on these packs ?

Hi, yes, I read that post and it's really great. I'm planning to get a TDS3012/4, but, what software I should use to send the magic command through the serial port (linked to RS232 to USB module) ?
Thanks in advance.
