Hello, I have posted questions about the HP8748A/B/C/D series of RF generators on the Keysight forum and also on the HP/Agilent group but the answers have been slim. So I am wondering if there is anyone from HP on the group that worked on these units or knows someone who did.
I have a unit that a resurrected (8648C) that had a bad battery and a bad A10 module. It appears that the unit is in calibration but when I turn the RF on the display on the bottom right switches from RF OFF to PULSE. The unit does not have the pulse option installed and is not indicated that there ever was on on the \ instrument option label. I have the service manual and there is a rather lengthy method to run Windoze based software to report the installed options but if I read the manual correctly any change to the option list (if you write the data back) clears the calibration data requiring a complete re-calibration of the instrument, something I would rather not do. So if anyone out there has any hacks out there to fix this I would greatly appreciate any info.
