What is the actual size of the E2960B (N5309A) PCIe Exerciser Data Memory?

The E2960B (N5309A) PCI Express internal data memory is 256K. This is a physical size of the N5309A data memory. The decoder may show a size that is larger than 256K of memory but this will wrap around and overwrite. The size and the data memory base address of the E2960B should be lined up to avoid overwriting.
