System Memory
The type and amount of system RAM in the instrument may vary depending on
the age and options installed in an instrument.
Standard instruments have either 1 or 2 GBytes of DDR DRAM, in either one or
two 184-pin DIMM memory modules, while instruments with Option PC2 will
have 4 GBytes of DDR SDRAM in two 200-pin SODIMM memory modules.
While the memory controller chips do support a wide range of DDR memory
types, only memory fully qualified by Keysight Technologies is supported. Full
qualification includes mechanical vibration and shock, thermal and power
dissipation and the basic electrical characteristics.
