Remote ControlExample: The ASCII character # denotes the beginning of the data block. The next numberspecifies the number of subsequent digits defining the length of the data block.In the example above, the four digits specify a length of 5168 bytes. The databytes follow next. During the transmission of these data bytes all terminators andother control characters are ignored until all bytes have been transmitted. In caseof data elements comprising more than one byte, the byte defined by the SCPIcommand “FORMat:BORDer” will be transmitted first.Overview of SyntaxElementsThe following list provides an overview of the syntax elements.‘ : ’ The colon separates the keywords of a command. In a command line, thecolon following a semicolon identifies the highest command level.‘ ; ’ The semicolon separates two commands in a command line.

An example of a white space is the space character.Description of CommandsNotationIn Appendix D: List of Commands, all commands implemented in the DDS200are tabulated according to the command system and described in detail. Thenotation largely conforms to the SCPI standard.Command table.Command:In the command column the table shows an overview of the commands andtheir hierarchical relationships (see indentations).DDS200 Digital Demodulation System User Manual 3–11
