TDS3000 Dallas RTC RAM Init
Miti:
I've got a Tek TDS3012B for $150 CAD, I hacked it to TDS3052B and sure enough the RTC battery was almost dead. I dug the old one out and installed a new one on the board, I didn't have the strength and/or the will to desolder it. I would like to reload the ~10K hours of operation and I would like to know if:
- Is it possible to do it through a command? I know I can erase it in Development mode but I'd like to load back the real time.
- Is there such thing as TDS3062? I see people hacking TDS30x4B to TDS3064B but nothing about TDS30x2B. Would it have any ill effect?
Cheers,
Miti

In this point even your lost your mac address, this scope can't connect to network because hasn't valid mac address

To initialize it, hold down the B-trig button while you power up the scope.
I don't know off hand if there's a way to set the power on hours using a console command although I suspect it is possible. I was able to work out where those values were stored and write them manually when I had the NVRAM out. I install a socket making it easy to swap in the future.
$150 CAD is a steal for a working TDS3000, even if it's only 2 channels. Fantastic instruments.

Must be other infos in the tds 3k threads here

Miti, i own the 3014B upgraded to 600Mhz. If you own the 6139A/B probes, as I do, dont bother to upgrade to 600Mhz. In my tests there is no difference compared side to side with my TDS3054 against a 600Mhz signal. Interestingly the original TDS3064B came as well with 4x 6139A probes. I wonder if TDS 600Mhz probes ever existed.
In the TDS3000B original documentation there was an illustrative comparative between TDS3054B and TDS3064B using different signals (using in both cases the 6139A probes) measuring rise time and amplitude, but I was unable to replicate these results.
