Tektronix TDS3012 with CORP MOD 89907 Label on Back

[whipaway]

I found this label on one of my TDS3012 'scopes. A Google search doesn't help, maybe someone here knows what it means? Modification, module, model?

I think it's "Corporate Modification". See e.g. page 8 of this PDF:
https://w140.com/tekwiki/images/1/16/ServiceTekNotes_51_Jun_1988.pdf

Apparently there was a "Corporate Service Support & Planning" group which developed, documented and published such modifications. I assume the sticker means that a specific modification has been implemented on your unit (by field service?).

yep  could be a specific demand  for an option, spec   etc ...    maybe if tek can  answer ??   

or opening the scope and try to do some photo compare ??

check the fw version too

Whatever it is, it must be pretty generic. This label also shows up on TDS5000/6000/7000/8000 series scopes. Given how little there is in common between these instruments, I'd speculate it's a broad modification for safety or EMC compliance, but I don't know for sure. It would be interesting to see inside photos for comparison.

eh      if it works fine
