Agilent Technologies E1300B DOWNloadCHECked SADDress, 1FC0016 + Laddr * 64 + registernumber

:DOWNload:CHECked

:SADDress

Parameters

DIAGnostic :DOWNload:CHECked :SADDress

DIAGnostic:CHECked:DOWNload:SADDress < address> ,< data> writes data to non-volatile User RAM at a single address specified by address using error correction. It can also write to devices with registers in the A16 address space.

Comments	• This command is typically used to send data to a device which accepts
	data at a single address. It is the only way to send binary data to single
	addresses over a serial (RS232C) line.
	• 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 either accounted for (NRAM segment
	sized to accommodate them), 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 (see
	example) 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:
	1FC0016 + (LADDR * 64) + register_number
	where 1FC00016 is the base address in the System Instrument A16 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.
