Parameters in Commands

There are four basic types of parameters: boolean, key words, variables
and arbitrary block program data.
Boolean
The expression OFF|ON|0|1 is a two state boolean-type parameter.
The numeric value 0 is equivalent to OFF. Any numeric value other
than 0 is equivalent to ON. The numeric values of 0 or 1 are commonly
used in the command instead of OFF or ON, and queries of the
parameter always return a numeric value of 0 or 1.
Key Word
The parameter key words that are allowed for a particular command
are defined in the command description and are separated with a
vertical slash.
Units
Numerical variables may include units. The valid units for a command
depends on the variable type being used. See the following variable
descriptions. If no units are sent, the indicated default units will be
used. Units can follow the numerical value with, or without, a space.
Variable
A variable can be entered in exponential format as well as standard
numeric format. The appropriate variable range and its optional units
are defined in the command description.
In addition to these values, the following key words may also be used in
commands where they are applicable.
MINimum - sets the parameter to the smallest possible value.
MAXimum - sets the parameter to the largest possible value.
1-6
Example
Command:
[SENSe:]CORRection:CSE
