9.1.3.1 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
The trace settings can be accessed via the function keys [Meas], [Format], [Scale],
[Trace], [Line], [Mkr] and [Mkr->]. They complement the Channel settings.
Each trace is assigned to a channel. The channel settings apply to all traces of the
channel.
9.1.3.2 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, ...)
Receiver step attenuators are not available for the R&S ZNLE (see Chapter 9.7.6,
"Receiver step attenuators", on page 303).
