General Rules The general rules for parameter usage is as follows:
•When a command has more than one parameter, the parameters must be separated by commas.
For example: OUT 1V, 2A.
•Numeric parameters may have up to 15 significant digits and their exponents can be in the range
±1.0E±20.
•Including too many or too few parameters causes a command error.
•Missing parameters cause an error, for example, the adjacent commas in OUT 1V, ,2A.
•Expressions, for example 4+2*13, are not allowed as parameters.
•Binary Block Data can be in one of two forms: Indefinite Length and Definite Length format (both
IEEE-488.2 standards).
Indefinite Length The Indefinite Length format accepts data bytes after the #0 until the ASCII Line
Feed character is received with an EOI signal (for RS-232 or Ethernet, just a line feed or carriage
return will terminate the block).
Definite Length The Definite Length format specifies the number of data bytes. The data bytes are
preceded by #n and an n-digit number. The n-digit number identifies how many data bytes follow. For
examples, see the *PUD command descriptions in Remote Commands.
Extra Space or Tab Characters
In the command descriptions in the Remote Commands section, parameters are shown separated by
spaces. One space after a command is required (unless no parameters are required). All other spaces
are optional. Spaces are inserted for clarity in the manual and may be left in or omitted. You can insert
extra spaces or tabs between parameters. Extra spaces within a parameter are generally not allowed,
except for between a number and its associated prefix or unit. See Remote Commands for examples of
commands whose parameters or responses are not self-explanatory.
