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.

ABORt Stops the current measurement
CALCulate Processes the measured data
CALibrate
Calibrates the R&S NRP2
CONFigure Specifies measurement settings (high-level commands)
DISPlay Configures the reading on the R&S NRP2 display.
FETCh Retrieves measurement results from the running measurement (high-level com-
mands)
