I recently acquired a TDS3054C that appears to be functional in all regards, except that I've had trouble accessing the built in web-server with modern browsers on my Windows 11 laptop or my Apple silicon (M3 Max) MacBook Pro.
I've updated the firmware on the 'scope to v 4.31, the most recent available on the Tektronix website.
On the Windows 11 laptop (an i7 Lenovo ideapad) recent versions of the Microsoft 'Edge' browser and the Google 'Chrome' browser simply wouldn't render the display windows served up by 'scope. Same for current Safari or Chrome browsers on my Apple silicon MacBook Pro.
As a sanity check, I tried viewing the 'scope pages with Internet Explorer and Chrome browsers running on a virtual Windows XP environment (hosted with VMWare Fusion on an i7 iMac). With that setup, I could view static screen-shots of the 'scope display, and the 'scope status window. Also, I could download and upload waveform data. However, I found that the tek.com 'cgi-bin/connect' service doesn't appear to be available.
After confirming that the 'scope was actually serving screen-shots and waveform data, I started looking for other 'legacy' browsers that would let me access the 'scope from the Windows 11 laptop. I found that the mypal browser () did the trick.
For accessing the 'scope from my Apple silicon MacBook Pro, the Firefox browser v129.0.2 does a great job.
Now, if there was just some way to download the cgi-bin/connect scripts from www.tek.com, or the tek 'escope' site was working, I'd be a happy camper.
