●
"Loss" is the loss of the filter at its maximum (or minimum) and is equal to the
response value of marker no. 1. For an ideal bandpass filter, the loss is zero (0
dB), for an ideal bandstop filter it is –
∞
dB.

Channel list and channel settings
The main properties of all channels assigned to the traces in the diagram are displayed
in the channel list below the diagram.
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
ZNA 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.
●
The
measurement mode identifier
section (optional) indicates a special test
mode of the channel, e.g. the measurement at arbitrary port frequencies ("Arb Port
n").
●
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
