As shown on this slide, the S21 magnitude in series mode is displayed by default. Other parameters such as S21 phase, S11 mag, S11 phase, Z mag, ESR, Q, or effective C will be displayed if selected. The graph frequency window displays from 50MHz to approximately 20GHz by default and can be narrowed by entering the desired start/stop frequency directly. The “Lock Y”, if checked, will keep the Y coordinate frozen when data display is changed. The marker will appear on the graph when the “Markers Freq” box is checked. This marker can be moved along the curve by dragging the marker on the graph, by pressing the up/down arrows, by clicking and dragging the square box, or by entering the frequency directly. The marker value will appear on the graph next to the cursor when “Disp Value” box is checked.
