3.3.1 IEEE 488 Interface
The Series 12000A permits data bus control in accordance with the IEEE Standard Digital Interface for
Programmable Instruments, IEEE STD 488.2. Table 3-3 shows the IEEE 488 standard subsets that are
implemented in the 12000A.
3.3.2 Command Syntax
The elements of the Series 12000A Native Interface Commands Codes are described in this section.
Because some commands are included only for compatibility with earlier models, there are some
variations in syntax from one command to another which must be carefully observed.
3.3.2.1 Function Codes
A native interface command includes a function code to indicate the nature and purpose of the
command. Some commands contain a function code and nothing else. Commands consisting only of a
function code are referred to in this manual as
simple commands. However, most commands consist of a
function code combined with other elements.
3.3.2.2 Address Assignment
The remote control address is assigned from the front panel of the instrument. The available range of
addresses is 0 through 30.
