Parameter Data Types

You may not specify a base in conjunction with either exponents or unit suffixes. Additionally, negative numbers must be expressed in decimal.

When a syntax definition specifies that a number is an integer, that means that the number should be whole. Any fractional part would be ignored, truncating the number. Numeric parameters that accept fractional values are called real numbers.

All numbers are expected to be strings of ASCII characters. Thus, when sending the number 9, you send a byte representing the ASCII code for the character "9" (which is 57, or 0011 1001 in binary). A three-digit number, like 102, will take up three bytes (ASCII codes 49, 48 and 50). This is taken care of automatically when you include the entire instruction in a string.

String data

String data may be delimited with either single (’) or double (") quotes. String parameters representing labels are case-sensitive. For instance, the labels "Bus A" and "bus a" are unique and can not be used interchangeably. Also pay attention to the presence of spaces, because they act as legal characters just like any other. So, the labels "In" and " In" are also two different labels.

Keyword data

In many cases a parameter must be a keyword. The available keywords are always included with the instruction’s syntax definition. When sending commands, either the long form or short form (if one exists) may be used. Uppercase and lowercase letters may be mixed freely. When receiving responses, uppercase letters will be used exclusively. The use of long form or short form in a response depends on the setting you last specified via the :SYSTem:LONGform command.
