Each line in the channel list describes a single channel. The channel of the active trace
is highlighted. The lines are divided into several sections with the following contents
(from left to right):
●
The "Channel Name" appears in the first section. The default names for new chan-
nels are Ch<n> with an automatically assigned number <n>. If a time domain
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 power of the internal signal source,
and the measurement 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]).
