Int Ref means the internal TXCO. Unfortunately I can't provide you with screenshots this time.
Anyway, you need to get the GPS receiver locked first. Take a look into the "Displaying Location Information Using GPS" section of the "E7495A/B Measurement Guide".

I got GPS fix! Unfortunately, it won't let me do the time base adjustment, I press the button and it will not allow me to continue, it doesn't say anything. I restored the elgato, but resulted in the same issue. The seller gave me the option to exchange it for a real "E7495B", I will probably do so (after I dump the drive).

I wouldn't exchange it! It seems like the L4600A is a better unit all around (better freq. range, better options, etc)... unless you can confirm that the L4600A software will truly turn the E7495 into an L4600A.

Maybe you need to set clock reference to the GPS before you do the adjustment.
L4600A seems to be a newer hardware, I wouldn't exchange it too.
It looks like they at least fixed very fragile PCB RF connections:

All right I will keep it then, thanks for the advice. My CF arrived, but I'm having problems copying some of the files, a few of them I can't even copy to Windows because the name is supposedly very long, but they are not (I will switch to Linux).
Also, it was funny to copy mnt into mnt, I didn't catch the loop.
With that said, what are the most important folders that should focus to rescue? Besides the flash folder of course. I already got out the easy ones: bin, etc, and home folder.
