Channel Menu
The Channel menu provides all channel settings and the functions to activate, modify and store different
channels.
Channels
A channel contains hardware-related settings to specify how the network analyzer collects data. The
channel settings can be divided into three main groups:
•
Control of the measurement process (Sweep, Trigger, Average)
•
Description of the test setup (internal source power, IF filters and step attenuators)
•
Correction data (Calibration, Offset)
The channel settings complement the definitions of the Trace menu. Each trace is assigned to a
channel, see Traces, Channels and Diagram Areas. The channel settings apply to all traces assigned
to the channel.
The Channel menu contains the following functions and submenus:
•
Stimulus defines the sweep range, depending on the sweep type.
•
Power Bandwidth Average defines the power of the internal signal source, sets the step
attenuators and the IF bandwidths, and configures the sweep average.
•
Sweep defines the scope of measurement, including the sweep type, the trigger conditions and
the periodicity of the measurement.
•
Mode opens the Port Configuration dialog to define the properties of the physical and logical
(balanced) test ports.
•
Channel Select provides functions to handle and activate channels.
•
Calibration provides all functions that are necessary to perform a system error correction
(calibration).
•
Offset provides a selection of length offset parameters to shift the measurement plane.
Stimulus
The Stimulus submenu defines the sweep range in the current channel, depending on the sweep type.
•
In Cartesian diagrams, the sweep range corresponds to the diagram width and defines the
scaling of the x-axis.
•
In polar diagrams and Smith charts the stimulus axis is lost but the marker functions easily
provide the stimulus value of any measurement point.
