    The corresponding sections of the same title provide simple programming examples for the R&S SMA100B. The purpose of the examples is to present all commands for a given task. In real applications, one would rather reduce the examples to an appropri- ate subset of commands.

  • Page 327: Mmemory Subsystem

    The /var/volatile directory serves as a RAM drive and can be used to protect sensitive information. The data is available temporarily. If option R&S SMAB-B85 is installed, the R&S SMA100B maps the user directory to the removable memory. If a memory is mounted, user data is saved there. Otherwise user data is redirected to the volatile memory.

  • Page 328: File Naming Conventions

    The file and the optional file extension are separated by a period sign. The R&S SMA100B distinguishes the files according to their extensions; each type of file is assigned a specific file content and hence a specific file extension. Refer to Chapter C, "Extensions for User...

    The subsequent commands for file handling (select, delete, read out files in the directory, etc.) require only specification of the filename. File extension can be omitted; after syntax evaluation of the used command, the R&S SMA100B filters out the relevant files.

    The following program example shows a simple TcpClient class that is intended to explain on how to get started with programming of sockets. The example sets up a socket communication to R&S SMA100B and opens a simple user interface, very similar to the telnet, which allows input of commands. To enable real automation, further development of the program is required.
