Rohde & Schwarz UPV Audio Analyzer - teardown and repair
harha:
Hi
Have updated the R&S UPV firmware-used a cloned ssa.Works ok but somehow the calibration are lost.Any here have experienced something similar??.
Have looked at the original ssd..cant see a cal file--could it be placed in the eeprom??.
Regards
Hardy

I no longer have one to check anything, but I do think calibration is stored on the boards and not in the firmware - though there isn't there some kind of selfcal or something available through the menu? May be worth digging into the manual and seeing if there's something available beyond the firmware initialization tests.
I remember having some issues updating the firmware as well - the Instrument (default XP user) account didn't have the full administrator privileges required to install the firmware, but they would execute without issue anyways. Going into the administrator account and then installing the firmware let them install properly, even for the Instrument user.
