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 System Overview). 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>'
CALCulate<Ch>:PARameter:DELete:ALL
CALCulate<Ch>:PARameter:DELete:CALL
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'
Display the generated trace (identified by its name Ch4Tr1) in diagram area no. 2 (window suffix 2),
assigning the trace number 9 (trace suffix 9) to it.
Active Traces in Remote Control
In manual control there is always exactly one active trace, irrespective of the number of channels and
traces defined. The active channel contains the active trace; see section Trace Settings in chapter System
Overview.
In remote control, each channel contains an active trace (unless the channel contains no trace at all), so
the notion of active channel is meaningless. This principle actually simplifies the remote control command
syntax, because it allows the active trace in a particular channel to be referenced by means of the channel
suffix. No additional trace identifier is needed; there is no need either to distinguish channel and trace
settings using mnemonics or suffixes.
