Agilent Technologies E1300B DIAGnosticDOWNloadSADDress, 1FC00016 + Laddr * 64 + registernumber

DIAGnostic:DOWNload:SADDress

Example Loading Dynamic Configuration information into an allocated RAM segment.

DIAG:NRAM:CRE 6	Allocate a segment of user
	RAM
DIAG:BOOT:WARM	Re-boot system to complete
	allocation
DIAG:NRAM:ADDR?	query starting address
enter value to variable X	get starting address into X
DIAG:DOWN < value of X> ,table data download table data
VXI:CONF:DCTAB < value of X>	link configuration table to
	configuration algorithm
DIAG:BOOT:WARM	Re-boot to set new
	configuration

:DOWNload:SADDress 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.

Comments	• 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:

1FC00016 + (LADDR * 64) + register_number

where 1FC00016 is the base address in the System Instrument A16 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 20000016 and address E0000016 is directly addressable by the Controller.

•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.
