MemorySize

Size of memory requested in A24 or A32 address space

Description

MemorySize indicates the size of the memory requested by the instrument in the A24 or A32 address space.

Some instruments use the A24 or A32 address space when the 64 bytes of A16 space are not enough for performing necessary functions. An instrument cannot use both the A24 and A32 address space. The address space is given by the MemorySpace property. If MemorySpace is A16, then MemorySize is 0.
