General Information : Programming with SCPI : Notational Examples

Notational Examples
Table: “Creating Valid Commands” provides examples of valid command syntax:
The first 2 commands set the location of marker 1. The third command sets the location of marker 2.
Command statements read from left to right and from top to bottom. In the command statement above, the :FREQuency keyword immediately follows the :SENSe keyword with no separating space. A space (sp) is used between the command string and its argument.
Note that the first keyword in the command string does not require a leading colon; however, it is good practice to always use a leading colon for all keywords. Note also that the :SENSe keyword is optional. This is a SCPI convention for all voltage or signal source type instruments that allows shorter command statements to be used.
The following is an example of a multiple command statement that uses two separate commands in a single statement:
:FREQuency:STARt 10E6;:FREQuency:STOP 20E9
Note 
Command Terminators
The <new line> character (ASCII 10) in the last data byte of a command string is used as a command terminator. Use of a command terminator will reset the command path to the root of the tree.
