MemorySize

Indicate the size of the memory requested in the 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.

Characteristics

Usage	VISA-VXI, VISA-GPIB-VXI
Read only	Always
Data type	Double

Values

The default value is 0.

Example

Create the VISA-VXI object vv associated with a VXI chassis with index 0, and an Agilent E1432A digitizer with logical address 130.

• vv = visa('agilent','VXI0::130::INSTR');
  fopen(vv)
  

The MemorySpace property indicates that the A24 memory space is supported.

• vv.MemorySpace
  ans =
  A16/A24
  

The size of the A24 space is

• vv.MemorySize
  ans =
  262144
