The channel settings complement the definitions of the T
r
ace 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.
(No direct access via front panel keys)
The Channel menu contains the following functions and submenus:
• Stimulus defines the sweep range, depending on the sweep type.
• Pwr Bw defines the power of the internal signal source, sets the step attenuators and the IF
bandwidths, and configures the sweep average.
• Cal provides all functions that are necessary to perform a system error correction (calibration).
• Sweep defines the scope of measurement, including the sweep type and the periodicity of the
measurement.
• Channel Select provides functions to handle and activate channels.
Stimulus
The Stimulus submenu defines the frequency sweep range in the current channel.
• 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.
• Center opens the input field for the center frequency. It corresponds to the center of the Cartesian
diagram, i.e. (Start + Stop)/2.
• Span opens the input field for the frequency span. It corresponds to the diagram width, i.e. (Stop –
Start).
• Start opens the input field for the the lowest frequency to be measured. It corresponds to the left
edge of the Cartesian diagram.
• Stop opens the input field for the highest frequency to be measured. It corresponds to the right
edge of the Cartesian diagram.
• Power defines the power of the internal signal source.
The Marker Functions provide a convenient alternative to the manual entry of the sweep range
parameters. Use the paste marker list for convenient entry of Start and Stop values.

For a frequency sweep the Start and Stop frequencies or the Center frequency and
Span are alternative settings:
