6 SCPI Command Reference
Standard Notations
A command consists of mnemonics (keywords), parameters and punctuation. Before you start to program your analyzer, familiarize yourself with the standard notation of each of them.
Keywords
Many commands have both a long and a short form: use either one. (a combination of the two is not allowed). Consider the:FREQuency command for example:
•Short form :FREQ
•Long form :FREQuency
SCPI is not case sensitive, so fREquEncy is just as valid as FREQUENCY, but FREQ and FREQUENCY are the only valid forms of the FREQuency command.
In this documentation, upper case letters indicate the short form of the keyword. The upper case and lower case letters indicate the long form of the keyword.
Punctuation
•A vertical bar "" dictates a choice of one ele- ment from a list. For example: <A><B> indicates that either A or B can be selected, but not both.
•Square brackets "[ ]" indicates that the enclosed items are optional.
•Angle brackets "< >" indicates a variable value to be defined.
•A question mark "?" after a command indicates that this command is a query. The instrument should return a data to the controller.
•A curly brackets “{ }” indicates a variable parameters to be defined.
