The BLASTER (U1 on the 2450-140 board) contains instrument logic, calibration data, and customer scripts,
readings, and data:
Two 16 MB nonvolatile NOR FLASH chips on the Digital board
One 128 MB volatile DDR2 SDRAM chip on the Digital board
The DISPLAY (U1 on 2450-110 board) contains instrument logic and customer setups and data:
Two 16 MB nonvolatile NOR FLASH chips on the Digital board
One 128 MB Volatile DDR2 SDRAM chip on the Digital board
Each instrument contains a battery-backed up clock that is used to generate timestamps. It does not
store data.
Older Model 2450s (Digital/Display board revision C) have two volatile DDR2 SDRAM chips for the
BLASTER and DISPLAY. However, the process for clearing and sanitizing data is identical.
Memory devices
The following tables list the volatile and nonvolatile memory devices in the standard instrument and listed
options.
