If I replace the backup battery will I loose the calibration?
According to the reference below, the calibration data is stored in EEPROM on the motherboard, which is non-volatile. Replacing the back up battery will not impact the stored calibration.
8648A/B/C/D Signal Generator Operation and Service Guide see page 206 (5a-8).
Hope this helps!
Well I changed the battery and now every time I power up it says Pulse Mode and Rear Input on the display. Didn’t do that before and my unit does not have the pulse option. Is there some reset I’m suppose to do?
Figured out how to do a factory reset. All well now.
