Agilent / HP / Keysight E1300A

This B size VXI mainframe provides 9 slots.

Two of the 9 slots are located internally and are dedicated to housing the 2 slot E1326B multimeter.

Three A size slots are also available for installing, for example, modules like the E1324A RS 232C/422 terminal interface.

This unit comes with 256K of non volatile battery backed RAM.

Two memory expansion boards (512K or 1M) may optionally be added.

This RAM is used for downloaded drivers and the run time memory that each instrument needs.

IBASIC may use the memory for program and RAM disk storage.

If only switch modules are installed, then the default of 256K is sufficient.

Otherwise, at least 1M is recommended.
