6.3 Basic remote control concepts
The functionality of the network analyzer's remote control commands has been defined
in close analogy to the menu commands and control elements of the graphical user
interface (GUI). The basic concepts of recall sets, traces, channels, and diagram areas
remain valid in remote control. Moreover, all commands follow SCPI syntax rules, and
SCPI-confirmed commands have been used whenever possible. These principles
largely simplify the development of remote control scripts.
The GUI and the remote control command set both aim at maximum operating conven-
ience. In manual control this generally means that the control elements are easy to find
and intuitive to handle, and that the effect of each operation is easy to verify on the
screen. Convenient remote control operation depends on a simple and systematic pro-
gram syntax and on a predictable instrument state; the display of results is secondary.
These differences suggest the peculiarities in the analyzer's remote control concept
discussed in the following sections.
6.3.1 Traces, channels, and diagram areas
Like in manual control, traces can be assigned to a channel and displayed in diagram
areas (see section Traces, Channels and Diagram Areas in Chapter 3). There are two
main differences between manual and remote control:
●
A trace can be created without being displayed on the screen.
●
A channel must not necessarily contain a trace. Channel and trace configurations
are independent of each other.

The colon separates the mnemonics of a command. In a command line, the separating
semicolon marks the uppermost command level.
The semicolon separates two commands of a command line. It does not alter the path.
The comma separates several parameters of a command.
The question mark forms a query.
The asterisk marks a common command.
Quotation marks introduce a string and terminate it.
The hash sign # introduces binary, octal, hexadecimal and block data.
Binary: #B10110
Octal: #O7612
Hexadecimal: #HF3A7
Block: #21312
A "white space" (ASCII-Code 0 to 9, 11 to 32 decimal, e.g. blank) separates header and
parameter.
