content: This TDS3012 came to me in an unusual state. At first I thought it was some sort of internal engineering build of the firmware, but while playing around in the menus I somehow managed to put the scope back in a "normal" state. I think I was messing around in the developer menu...Weird...I really wish I hadn't put the scope back to default, I wanted to play some more.

content: Were you just in some part of the Service menu ?For a TDS2k from the Service manual:1. Power on the oscilloscope.2. Push the front-panel MEASURE button to access the MEASURE menu.3. Push the top option button to access the Measure 1 menu.4. Push and hold the front-panel SINGLE SEQ button.5. Push and hold the front-panel AUTOSET button.6. Wait at least two seconds.7. Release the SINGLE SEQ button.8. Release the AUTOSET button. A message appears in the lower left corner ofthe screen stating “Service mode ON.”9. Push the front-panel UTILITY button. The last item in the Utility menu isnow “Service.”At completion of the Adjust procedure disable the “Service” menu through theUTILITY front panel button, the “Service” option button, and the “Service”Mode Off” option button.

content: Quote from: Jwalling on November 04, 2018, 10:27:45 amOK the 3k seems a bit different.From the TEK wiki sitehttp://w140.com/tek_tds_3000_series_service.pdfFactory Adjustment ProcedureTo perform the factory adjustment procedure, do these steps:1. Locate the hole that provides access to the CAL switch on the rear panel.CAL2. Put the adjustment tool into the CAL switch hole. Push and hold the CAL switch in while you power on the oscilloscope. Release the switch when the oscilloscope shows the power-on message with the oscilloscope graticule in the background.3. Push the SAVE/RECALL button.4. Push the Recall Factory Setup screen button.5. Push the OK Confirm Factory Init screen button to restore factory settings prior to doing the factory calibration.6. Push the MENU OFF button.7. Push the UTILITY button.8. Push the System screen button to select Cal.9. Push the Factory screen button.10. Push the OK Do Factory Calibration screen button to start the adjustment process11. Connect signals from the DC voltage source, leveled sine wave, or fast-rise generator as instructed by the oscilloscope display. After you connect the correct signal, push the OK Do Next Step screen button to continue theprocess.NOTE. The oscilloscope adjusts itself automatically using the reference signal from the DC voltage source, leveled sine wave, or fast-rise generator. There are no manual oscilloscope adjustments that you need to make.If you make an error, such as connecting the wrong input signal, you can repeat the last step by pushing the Return to Previous Screen screen button.12. Continue the adjustment process until it is complete. You can abort the process at any time by pushing the MENU OFF button or by changing to a different menu.

content: Quote from: Jwalling on November 06, 2018, 10:28:44 amI remember once diving into my TDS2012B service menu and the 'adjustment' is just one part of the service menu.A smart guy like you wouldn't be changing anything.Maybe with the Cal switch left OFF you can still enter the menus and just have a look around for the 'hidden' menu you were in.

I managed todisable it and now it does not appear anymore. I was wondering how it can be activated again...I didn't get to see all the things that it can control...OK, you talked me into it.

content: strangeseems hardly anybody have seen this. My guess is that there must be a remote command that puts the scope in that mode. or maybe a combination of keys during boot.I thought people who have worked on the firmware and found out all those passwords and way to upgrade the BW would know...

content: Just came across the same 'issue' (on a 3.27 FW version)And just as others, I (somehow unintentionally) managed to get back to 'normal'Would be really interested, it was definitely a developer menu, and was persistent, as described.There were LCD testing menus, DAC settings (gain, offset,...), and a bunch of other interesting things... can't believe no one here knows how to enter this DEV mode?

content: Anyone here knows how to extract the actual firmware file ?? (and/or would have one, version doesn't matter much).I'm not too bad with PowerPC assembler, would really like to dig into this to find out how to activate that mode... but don't wanna spend hours trying to figure out how to extract/reconstruct the actual image from the 3-4 floppies (not even sure a still have a working floppy btw...)

Should be simple enough to do it.

content: In fact, the info was already available in another thread...(although without mentioning the 'PacmanBuildView' that appears in the version popup)Press the 'Select' button while powering it on, for quite a while, until it's completely started.That brings new (and relatively self-explanatory) items in the Utility menus.Have fun !

content: Quote from: darkstar49 on October 05, 2020, 04:01:44 pmnobody really ever explored the firmware on these scopes. I am sure there must be a command that you can send from LANto enable/disable the dev mode. Such command exists on later models (DPO, MSO....) (DEV MOD 0,1 and MFG MOD 0,1) and I think it must have existed on these models too. I don't have the scope anymore but maybe someone can simply try these commands and see if they work

content: on the other hand, if it's for your own use, who cares ? You can either leave it in DEV mode forever, or just ignore that you'll have the counters wiped...And in most of these good old boys, the NVRAM should be replaced anyway, time for a backup before playing around. ;-

content: Quote from: darkstar49 on October 06, 2020, 10:03:06 amtrue. even if you sell it, shouldn't be a problem (I did) and there are couple of sellers on ebay selling these that show very low number of power ons and low hoursthe operating hours can be easily restored, unfortunately nobody seems to know how to restore the number of power ups. Seemingly it is not stored in the NVRAM

content: How to enter and exit Devel mode.On my TDS3064B , I exited Devel mode by the following:Utility->Config->Tek Secure Erase MemoryUtility->Diags->Error Log still shows power ups, and operating hours.Activating Devel mode is by holding SELECT while turning on power, until traces are shown.POST screen is not seen.I did not see the pacmanBuildView display, maybe because my scope has B at end of part number
