The type of each trace in a diagram is indicated in the trace list: "MEM<no>" at the
beginning of the trace name indicates a memory trace (with default naming), Math at
the end of the trace label indicates a mathematical trace. You can also hide a trace
("Invisible") without deleting it.
Trace list and trace settings
The main properties of all traces assigned to the diagram are displayed in the trace list
in the upper part of the diagram.
Each line in the trace list describes a single trace. The active trace is highlighted
("Trc5" in the example above). The lines are divided into several sections with the fol-
lowing contents (from left to right):
●
The
trace name
appears in the first section. The default names for new traces are
Trc<n> with n automatically selected. A "Mem..." at the beginning of the trace
name indicates a memory trace (default naming). To change the trace names,
open the "Trace Manager" from any trace name segment's context menu.
●
The
measured quantity
(e.g. an S-parameter or a ratio) appears on a colored
background. The source port for wave quantities and ratios is indicated in brackets.
●
The
format
section shows how the measured data is presented in the graphical
display. Use the context menu of the format section to change the format of the
related trace.
●
The next sections show the value of the vertical or radial diagram divisions ("Scale
Div.") and the reference value ("Ref").
●
The
channel
section shows the channel that each trace is assigned to. It is omitted
if the all traces in the diagram are assigned to the same channel.
●
The
type
section indicates "Invisible" if a trace is hidden and Math if the trace is a
mathematical trace. "Gat" indicates that a time gate is active for the trace. Use the
"Mem Math" and "Traces" tabs of the Trace softtool to display and hide data and
memory traces, and to define mathematical traces.
●
The respective section's context menu (except for the type section) provides
access to the most common related tasks.
●
If the size of the diagram is too small, some of the sections are hidden. Enlarge or
maximize the diagram to display all sections.
