This chapter is not intended to teach you everything about the SCPI programming language. If you are using an optional programming compatibility modes, you should refer to the manual that came with the option.

  • Page 20: Overview

    Programming with SCPI requires knowledge of: • Computer programming languages, such as C, C++, and MicrosoftâVisual Basicâ. • The language of your instrument. The N9320B employs SCPI as its programming language. The semantic requirements of your controller’s language determine how the programming commands and responses are handled in your application program.
  • Page 21 Programming Fundamentals Overview Common Terms used in this Book Terms Description Controller Any computer used to communicate with an instrument. A controller can be a personal computer (PC), a minicomputer, or a plug-in card in a card cage. Some intelligent instruments can also function as controllers.

    Status Registers Overview Overview When you are programming the instrument you may need to monitor instrument status to check for error conditions or monitor changes. You need to determine the state of certain instrument events/conditions by programming the status register system. IEEE common commands (those beginning with *) access the higher-level summary registers.
