●
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 Config softtool to display and hide data
and memory traces, and to define mathematical traces.
●
If multiple DUTs are configured (R&S
Measurements on Multiple DUTs"
on page 80), the label is extended by an addi-
dional section indicating the
measured quantity from the related DUT's per-
spective
. The section contains the DUT's assigned name and the measured quan-
tity expressed using the DUT's logical port numbers, separated by a colon.
In the example above we have a DUT named "DUT_2", whose logical ports 2 and
1 are connected to the logical analyzer ports 6 and 5, respectively. The S
65
from
the VNA perspective corresponds to S
21
from the DUT's perspective.
●
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 will be hidden. Enlarge
or maximize the diagram to display all sections.
