The command trees for the SCPI command set implemented in the 2201R are described in this manual.
Syntax and notation
There are two types of SCPI commands:
• compound commands
• common commands.
Both types of commands differ in syntax.
Compound commands
Compound commands are always referred to as commands throughout this chapter.
• Any compound command is built in a hierarchical way. The single command elements are separated by colons
(:).
• A command usually starts with a colon (:). However, the colon must be omitted when the subsequent command
continues on the same hierarchical level (see examples below).
• The first command element always is the name of the subsystem like CONFigure or MEASure.
• Then follows one of the commands available for that subsystem like GSM or RFTX.
• The subsequent command element(s) may now be one or more subcommand(s) and/or one or more parameter
term(s) (e.g. BS:ID:BCC 5).
• A SCPI program line may contain more than one command. In this case, the single commands have to be sepa-
rated by a semicolon (;).
• There is also a short form for every command. This is usually formed of the first four letters (CONF instead of
CONFIGURE). When the fourth letter is a vowel (a,e,i,o,u), only the first three letters are used (RFG instead of
RFGenerator).
• Throughout this manual, the short form is always written in capitals to make it easy to identify. However, the
SCPI system of the 2201R is not case-sensitive.
Examples
• The complete SCPI command to set the base station color code (i.e. the training sequence) to 5 would be:
:CONFigure:GSM:BS:ID:BCC 5. The short form :CONF:GSM:BS:ID:BCC 5 is completely identical.
• :RFGenerator:STATe ON is identical with :RFG:STAT ON. However, the long version of the commands
is – especially in the beginning – easier to work with.
• :RFGenerator:STATe ON; LEVel 20 is a valid two-command statement. STATe ON and LEVel are
both commands of the RFGenerator subsystem. Both are working on the same hierarchical level. Therefore,
the colon in front of LEVel 20 has to be omitted.
An alternative with the identical meaning would be: :RFGenerator:STATe ON; :RFGenera-
tor:LEVel 20. The form :RFGenerator:STATe ON; :LEVel 20 would be invalid, because LEVel
is no subsystem of the 2201R.
• :RFGenerator:MODulation:STATe ON is invalid. STATe ON is no subcommand of the :RFG:MOD
level.
• :RFGenerator:MODulation ON; FREQuency 850.2 In this case, the first part up to the semico-
lon(;) is valid. The second part is invalid as FREQ is no subcommand of the :RFG:MOD level.
The correct command would be: :RFGenerator:MODulation ON; :RFGenerator:FREQuency
850.2.
Parameters
Many commands require parameters to be specified. Those parameters are placed behind the command, separated
by at least one blank (space).
