I’m trying to find out whether the bandwidth upgrades on the Agilent/Keysight DSO/MSO9000 require servicing or if these are ‘field-installable’ (i.e. by key)
Some docs mention that returning it to a Keysight service center is mandatory, but I’d like to know whether that’s in fact for the calibration only, or if this is ‘really’ required for the bandwidth upgrade as well ? In other words, is anything achievable by option key only (although without the proper calibration/adjustment tables) ?
Any pointers/feedback welcome !
