[time-nuts] Agilent 53132A Needs Help

I'd be inclined to take the error message at face value; you have some
corruption in EPROM or flash memory that isn't in an area that gets used
during the measurements you're making.  Contacting an Agilent rep would make
sense, as the 53132A is new enough that there might be an easy way to
upgrade/reflash the firmware.
