3.2.4 IEEE-488 Command Format
The IEEE-488 commands are configured in Root format. There are six levels of the instruction
from top to bottom. Follow the specific path (as illustrated in Figure 3.3) to configure a specific
command. The colon at the beginning of each line denotes that all line signals are root. Use a
colon (:) to separate levels. Use the semicolon (;) to separate two commands on the same line.
For example, to format the command for the LC function, use this path:
:CALCulate:LIMit:FORMat:LC
If the command is a setting, then put the parameter after the instruction. If the command is an
inquiry, then put a question mark (?) after the instruction.
For example, to set the beeper to sound on Fail:
:CALCulate:LIMit:BEEPer:CONDition:FAIL
To inquire what the beeper is set to:
:CALCulate:LIMit:BEEPer:CONDition?
The Ending Code can be any type in Table 3-5.
