Tektronix deprecated free trial options

[Circuitauger]

Hello,

Been needing to get some options onto my Tektronix TDS series oscope for some signal analysis. Found Tek still has the free trial & download of the software package option on their website, installed, everything works fine. The issue however is that unfortunately it seems that Tektronix no longer actually sells license keys and/or option keys for any of their older equipment. 

So currently I’m stuck just leaving the thing on so the number of remaining code launches doesn’t decrement to 0.

Saw on the forums here there’d been discussion on hacking the scopes to unlock options, don’t know if I need to go down that road yet.   

Does anyone know how the remaining trial boot up counter works? Is it writing to some eprom, or can the hdd just be frozen in time from changes, or the trial software just indefinitely uninstalled and reinstalled?

The TDS family consists of dozens and dozens of models. What scope, specifically, are you talking about here?
