6.3 Overview of SCPI Command Systems
The SCPI commands are grouped in command systems according to their function.
Only the most important functions are shown in the figures.
The commands are separated in high-level commands and low-level commands. The
high-level measurement commands combine several low-level setting commands in
one command, see chapter 6.4, "High-Level Measurement Commands (CONFigure,
MEASure, READ and FETCh)", on page
208.
The individual commands are described in alphabetical order in the following chapters.
The high-level measurement commands are put first.

Fig. 6-1: Overview of SCPI command systems and their mutual interaction
The figure above gives an overview of the SCPI command systems of the R&S NRP2.
The measured values are forwarded to the SENSe block where they are processed
and handed to the CALCulate blocks. The values from the SENSe block are not
immediately made available to the user, but only after they have been processed in the
CALCulate blocks. In the
CALCulate blocks, the values of several sensors can be
processed together before they are output. High-level commands may be used to con-
figure SENSe and CALCulate blocks with a single command. This may considerably
simplify operation of the R&S NRP2. The frequency-dependent correction tables for
the measured values are managed by the MEMory command system.
