something strange to display such an unfinished calibration menu in a place where we, the users, would touch it.

Yes, my 6114A has an exe file with a GUI that looks like the  'Calibration View' GUI shown in post #4  as c.jpg.

It's over a year since I did this, but I recall that the RSA6114A normally transfers the cal data for the 10MHz oscillator from secure FLASH to volatile RAM during bootup. I think it then uses the value held in RAM to set the value for the frequency trim of the oscillator. I recall that I was able to tweak the value in RAM until the oscillator was within 0.01 Hz of 10 MHz and then I transferred this new cal data into FLASH memory so it loaded the corrected data into RAM during any subsequent reboots. I'm fairly certain that I used that Calibration View menu to do it all.

Note that I think it is possible to trash the various calibration tables for this analyser if that GUI is used incorrectly. I made sure I made several copies of all the various calibration data files before I attempted anything.
Once you overwrite anything in FLASH you won't be able to put it back to the previous state unless you have a valid copy of the original cal data that you can reload into FLASH.
