  • Page 3: Programming Overview

    SIGLENT 1. Programming Overview SSA3000X Series Spectrum Analyzer support both USB and LAN interfaces. By using these interfaces, in combination with NI-VISA and programming languages, users can remotely control the spectrum analyzer. Through LAN interface, VXI-11, Sockets and Telnet protocols can be used to communicate with the spectrum analyzer. This chapter introduces how to build communication between the spectrum analyzer and the PC.

    SIGLENT 4. Programming Examples This chapter gives some examples for the programmer. In these examples you can see how to use the VISA or sockets, in combination with the commands have been described above to control the spectrum analyzer. By following these examples, you can develop many more applications.
