The active traces are handled as follows:
●
After a preset (
*RST
), the analyzer displays a single diagram area with the default
trace no. 1 named
Trc1
. The trace is active in manual and in remote control.
●
In manual control, a new, added trace automatically becomes the active trace. To
select another trace as the active trace, tap inside the trace list.
●
In remote control, a new trace added via
CALCulate<Ch>:PARameter:SDEFine
'<trace_name>', '<parameter>'
also becomes the active trace. To select
another trace as the active trace, use (
CALCulate<Ch>:PARameter:SELect
'<trace_name>'
).
●
The active traces for manual and remote control may be different.
Example:
*RST
Reset the analyzer, creating channel no. 1 with the default trace "Trc1". The trace is
displayed in diagram area no. 1.
CALC1:PAR:SDEF 'Trc2', 'S11'
;
DISP:WIND:TRAC2:FEED 'Trc2'
Create a new trace named "Trc2", assigned to channel no. 1 (the suffix 1 after
CALC
,
may be omitted), and display the trace. The new trace automatically becomes the
active trace for manual and for remote control. To check this, tap "Trace – Marker –
Marker 1" to create a marker. The marker is assigned to "Trc2". Delete all markers
("Trace – Marker – All Markers Off").
CALC1:MARK ON
Example:
To verify that "Trc2" is also active for remote control, use the channel suffix 1 after
CALC
(may be omitted) to reference the active trace in channel 1 and create a marker
"Mkr 1". The marker is assigned to "Trc2".
Example:
CALC:PAR:SEL 'Trc1'
;
CALC1:MARK ON
Select the old default trace "Trc1" as the active trace for remote control. Create a new
marker to verify that "Trc1" is now the active trace in channel 1.
In the SCPI command description, the numeric suffix
<Ch>
is used for channel settings
(it denotes the configured channel), whereas
<Chn>
is used for trace settings (it refers
to the active trace in the channel).

Initiating measurements, speed considerations
After a reset the network analyzer measures in continuous mode. The displayed trace
shows the result of the last sweep and is continuously updated. This provides a perma-
nent visual control over the measurement and the effect of any analyzer settings.
In remote control, it is advisable to follow a different approach in order use the analyz-
er's resources to full capacity and gain measurement speed. The following principles
