Measurement elements
There are several elements that make up a measurement: Port setup, Sweep type,
Generator frequency and power, Detector settings and Bias settings and configuration.
These elements are accessible through tabs with panels.
This chapter explains the functions of the measurement and other tabs.
Setting measurement parameters
Measurement parameters define the measurement to be made. These parameters can be
set by hand, or recalled from a previous saved session or a preset.
The parameters that control the measurements are Frequency, Power, Attenuation, Bias
Voltage and Bias Current. These parameters are controlled by a standard edit box.
Depending on the sweep configuration a
parameter can be
stepped or fixed during
the sweep. The field indicates a sweep
parameter with the blue arrow and a fixed
parameter with the blue vertical bar.
The sweep parameters allow entry of start,
stop and step values as well as the dwell time (time during each measurement point).
The fixed parameters allow setting the fixed value and show the minimum and maximum
allowed values.
When a field is double-clicked a numerical entry screen allows entry of a number by
mouse or touch screen. It also shows the minimum and maximum allowed value.
Sweep parameters always yield one more measurement point than the number of
steps : the endpoint of the sequence will be included.
Screen
The screen tab minimizes the control panel in order to maximize the graph area.
