Since I don't use the scope too often, I think I am going to deploy an automated weekly or monthly self-cal.
The scope have Ethernet connectivity so self cal can be initialized and queried by my always-on server. Just power the scope with an Ethernet-enabled power strip (so I can bypass the clunking power button, leaving it always on, and switch the power to it in software)
I need to cook up software for this task, and set up a cron job on my server to run it periodically.
