General Rules The general rules for parameter usage is as follows:
1. When a command has more than one parameter, the parameters must be separated by
commas. For example: OUT 1V, 1 KHZ .
2. Numeric parameters may have up 15 significant digits and their exponents can be in
the range +/-1.0E+/-20.
3. Including too many or too few parameters causes a command error.
4. Null parameters cause an error, e.g., the adjacent commas in OUT 1V, ,1 KHZ .
5. Expressions, for example 4+2*13 , are not allowed as parameters.
6. Binary Block Data can be in one of two forms: Indefinite Length and Definite Length
format (both IEEE-488.2 standards).
Indefinite Length The Definite Length format accepts data bytes after the #0 until
the ASCII Line Feed character is received with an EOI signal (for RS-232 just a line
feed or carriage return will terminate the block).
Definite Length The Definite Length format specifies the number of characters that
will follow in the <digits> field. These characters must be 0 to 9 (ASCII 48 to 57
decimal). The value of the number in the <digits> field defines the number of user
data bytes that will follow in the <user data> field. For examples, see the UUT_SEND
and *PUD command descriptions in Chapter 6.
5-38. Extra Space or Tab Characters
In the command descriptions in Chapter 6, 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 as desired. You can insert extra spaces or tabs between parameters as desired.
Extra spaces within a parameter are generally not allowed, except for between a number
and its associated multiplier or unit. Chapter 6 contains examples for commands whose
parameters or responses are not self-explanatory.
