Variable

Part with heading “Variable” describes necessary variables when using the object. It gives the description, data type, allowable range, preset value, unit, resolution, and notes for variable (italic) shown in the syntax.

Variables declared as the string data type (String) are case insensitive. For variables of the string type that indicate arguments (written as Param in the syntax), you can omit lower-case letters.

The data types of the E5061A/E5062A COM objects include 5 types as shown in Table 7-1. Before using variables, declare the data type of each variable. If you do not declare the data type of a variable, it is automatically dealt as the variant type.

Table 7-1		Data type
Data type	Name		Consumed	Range
			memory
Long	Long integer		4 bytes	-2,147,483,648 to 2,147,483,647
	type
Double	Double		8 bytes	For a negative value:
	precision			-1.79769313486232E+308 to -4.94065645841247E-324
	floating point			For a positive value:
	type
				-1.79769313486232E+308 to -4.94065645841247E-324
Boolean	Boolean type		2 bytes	-1 (True) or 0 (False)
String	Character		1	Up to approximately 2 billion characters
	string type *1		byte/alphan
			umeric
			character
Variant	Variant type		16 bytes	No limitation

*1.For a fixed length string, declare the number of characters.
