I have installed a RAMTRON FRAM FM1608-120-PG device in a 2465B
(socketed in case it didn't work). So far it works beautifully. I had
to perform all CAL procedures since the device was blank.
I suppose if a scope has valid calibration data in the NVRAM it could
be copied over to the new FRAM using an EPROM programmer that supports
RAM (many do).
The scope I put the FRAM in needed calibration anyways.
So far everything is working great.
