The active traces for manual and remote control may be different.
The following program example illustrates how to create, select and reference traces. It
is instructive to observe the analyzer screen in order to check the effect of each step.
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).
6.3.3 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
can help to optimize a remote control program (see also programming example in
Chapter 8.1.1, "Typical stages of a remote control
●
Switch off the measurement while configuring your instrument.
●
Use a minimum number of suitably positioned sweep points.
●
Start a single sweep, observing proper command synchronization, and retrieve
your results.
The following command sequence performs a single sweep in a single channel.
