Special Remote Control Features
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 setups, 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 convenience. 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 program 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.
Traces, Channels, and Diagram Areas
Like in manual control, traces can be assigned to a channel and displayed in diagram areas. 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 following frequently used commands create and delete traces, channels, and diagram areas:
Create new trace and
new channel
(if channel <Ch> does not
exist yet)
CALCulate<Ch>:PARameter:SDEFine '<Trace Name>',
'< Meas Parameter>
Delete trace CALCulate<Ch>:PARameter:DELete <Trace Name>
Create or delete channel CONFigure:CHANnel<Ch>[:STATe] ON | OFF
Create or delete diagram
area DISPlay:WINDow<Wnd>:STATe ON | OFF
Display trace in diagram
area
DISPlay:WINDow<Wnd>:TRACe<WndTr>:FEED
The assignment between traces, channels, and diagram areas is defined via numeric suffixes as
illustrated in the following example:
CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
Create channel 4 (channel suffix 4) and a trace named Ch4Tr1 to measure the input reflection coefficient S
11
. The
trace is created but not displayed.
DISP:WIND2:STAT ON
Create diagram area no. 2 (window suffix 2).
DISP:WIND2:TRAC9:FEED 'CH4TR1'
