transform is active, the R&S
ZNL/ZNLE displays an additional line to indicate the
stimulus range of the displayed time-domain trace.
Open the "Channel Manager" from the name segment's context menu to change
the channel name.
●
Start
indicates the lowest value of the sweep variable (e.g. the lowest frequency
measured), corresponding to the left edge of a Cartesian diagram.
●
The
color legend
shows the display color of all traces assigned to the channel.
The colors are different, so the number of colors is equal to the numbers of traces
assigned to the channel.
●
The values behind the color legend show the
constant stimulus value
, which is
either the power of the internal signal source (for frequency sweeps and time
sweeps) or the CW frequency (for power sweeps; R&S
ZNL only), and the mea-
surement bandwidth ("BW").
●
Stop
indicates the highest value of the sweep variable (e.g. the highest frequency
measured), corresponding to the right edge of a Cartesian diagram.
Open a segment's context menu to access common related tasks.
Example:
The following context menu is assigned to the channel name section:
The settings in the context menus correspond to the most common functions in the
"Channel" > "Channels" softtool tab (hardkey [Channel]), the "Stimulus" softtool (hard-
key [Freq] and [Span]), the "Sweep" > "Sweep Params" softtool tab (hardkey [Sweep])
and the "Bw Avg Power" softtool (hardkey [Bw Avg Power]).

Context menus
To provide access to the most common tasks and speed up the operation, the VNA
mode offers context menus (right-click menus) for the following display elements:
●
Diagram
●
Marker info field
●
Trace list (separate context menus for trace name section, measured quantity sec-
tion, format section, scale section, and channel section)
●
Channel list (separate context menus for channel name section, sweep range sec-
tion, additional parameter section)
To open a context menu associated with a display element, tap and hold the element
for some seconds. Right-click the display element if you are using a mouse.
