High-level memory write to VXI register
memwrite(obj,data)

memwrite(obj,data,offset,'precision

memwrite(obj,data,offset,'precision

| A VISA-VXI or VISA-GPIB-VXI object. |
| The data written to the memory address. |
| Offset for the memory address space. |
| The number of bits to write to the memory address. |
| The memory address space. |
memwrite(obj,data)
writes the
uint8
value specified by data
to the A16
address space with an offset of 0 for the object obj
.
data
can be an array of uint8
values.
memwrite(obj,data,offset)
writes
data
to the A16 address space with an offset specified by
offset
. offset
is specified as a decimal
value.
memwrite(obj,data,offset,'
writes precision
')data
with precision specified by
precision
. precision
can
be uint8
, uint16
, or
uint32
, which instructs memwrite
to write
data
as 8-, 16-, or 32-bit values, respectively.
precision
can also be single
,
which instructs memwrite
to write data
as
single-precision values.
memwrite(obj,data,offset,'
writes precision
','adrspace
')data
to the address space specified by
adrspace
. adrspace
can be
A16
, A24
, or A32
. The
MemorySpace
property indicates which VXI address spaces are
used by the instrument.
Create the VISA-VXI object vv
associated with a VXI chassis
with index 0, and a Keysight™ E1432A digitizer with logical address 130.
vv = visa('keysight','VXI0::130::INSTR'); fopen(vv)
Perform a high-level write to the fourth instrument register, which has an offset of 6.
memwrite(vv,45056,6,'uint16','A16')
Disconnect vv
from the instrument.
fclose(vv)
Refer to Using High-Level Memory Functions for a description of the first four registers of the E1432A digitizer.
Before you can write to the VXI register, obj
must be connected
to the instrument with the fopen
function. A connected
interface object has a Status
property value of
open
. An error is returned if you attempt a write operation
while obj
is not connected to the instrument.
