The A16 base address used in register-based programming depends on whether the A16 address space is located inside the E1405/06 Command Module or elsewhere (e.g. embedded computer). Figures C-1A, C-1B, and Table C-1 enable you to determine the base address for the following computer configurations:

LADDR : Amplifier logical address.

(LADDR * 64)16: multiply quantity, then convert to a hexadecimal number (e.g. 88 * 64)16 = 160016. When using DIAG:PEEK? and DIAG:POKE, the width (number of bits) is 8 or 16.
