DIAGnostic:DOWNload:SADDress < address> ,< data> writes data to
non-volatile User RAM at a single address specified by address, and writes data
to devices with registers in A16 address space.

data arbitrary block
program data
Most computers terminate an OUTPUT, PRINT, or WRITE statement
with a carriage return or carriage return and line feed. These
End-Of-Line characters must be accounted for or suppressed using an
appropriate IMAGE or FORMAT statement. Some helpful methods:
– Control the End-Of-Line characters with format statements.
– Use the Definite Length Arbitrary Block Program Data format to send
your data rather than the Indefinite Length Arbitrary Block Program
Data format.
A register address in A16 address space can be determined by:
1FC000 + (LADDR * 64) + register_number
16
where 1FC000 is the base address in the System Instrument A16
16
address space, LADDR is the device logical address, 64 is the number of
address bytes per device, and register_number is the register to which the
data is written.
If the device is an A24 device, the address can be determined using the
VXI:CONF:DLISt command to find the base address in A24, and then
adding the register_number to that value. A24 memory between address
200000 and address E00000
16
Address may be specified in decimal, hex (# H), octal (# Q), or binary
(# B) formats. DOWNload is done by word (16 bit) access so address
must be even.
