5.1.3.1
Trace Settings
The trace settings specify the mathematical operations used to obtain traces from the
measured or stored data. They can be divided into several main groups:
●
Selection of the measured quantity (S-parameters, wave quantities, ratios, impe-
dances,...)
●
Conversion into the appropriate display format and selection of the diagram type
●
Scaling of the diagram and selection of the traces associated to the same channel
●
Readout and search of particular values on the trace by means of markers
●
Limit check
Each trace is assigned to a channel. The channel settings apply to all traces of the
channel.
5.1.3.2
Channel Settings
A channel contains hardware-related settings which specify how the network analyzer
collects data. The channel settings can be divided into three main groups:
●
Description of the test setup (power of the internal source, IF filter bandwidth, port
configuration, receiver step attenuators, ...)
●
Control of the measurement process (sweep, trigger, averaging, ...)
●
Correction data (calibration, offset, ...)
5.1.3.3
Active and Inactive Traces and Channels
A window can display several diagrams simultaneously, each with a variable number of
traces. One of these traces is active at each time. The
active trace
is highlighted in the
trace list on top of the active diagram (Trc4 in the figure below):
