Keysight E1459A Register Definitions
For example, for the Keysight 75000 Series C Mainframe with an Keysight E1406
Command Module, VXI A16 address space starts at 1F0000
Keysight E1406 Command Module, the A16 space is divided so modules are
addressed only at locations beginning with C000
allocated 64 register addresses (40
logical address set by the logical address switch on the module:
For the Keysight E1459A, the factory-set logical address is 144 (90
