Smith chart software series#

To see both the XY chart and the Mini-Smith at the same time you must have your screen resolution set to 1024x768 or higher and you must maximize both the Excel window and the workbook sub-window (using the lower set of size buttons). On the secondary (right side) Y axis you can also choose '(none)' to indicate no secondary plot line.Ī Mini-Smith chart is shown on the same sheet with the XY chart. The order of the items in the above list has no special significance other than that the items most likely to be chosen for plotting are near the top.

Smith chart software series#

Negative values for Ls, Cs, Lp, and Cp may be interpreted to mean the amount of inductance or capacitance which must be added, in series or parallel respectively, to 'cancel out' the corresponding reactance. In Zplots it is plotted as a negative number merely as a convenient way to show a reverse scale, with zero at the top and higher (magnitude) values lower down. Note concerning RL: Return loss is of course a positive number.

Cp (pF) - Equivalent capacitance for parallel Xp, both positive and negative.

Lp (µH) - Equivalent inductance for parallel Xp, both positive and negative.

Cs (pF) - Equivalent capacitance for series Xs, both positive and negative.

Ls (µH) - Equivalent inductance for series Xs, both positive and negative.

Phase (deg) - Reflection coefficient angle.

RL (dB) - Return Loss, plotted as a negative number to show 'reverse' scale ( see note below).

Rho (mag) - Reflection coefficient magnitude.

On the primary (left side) or secondary (right side) Y axis you can plot: Frequency (in MHz) is always shown on the X axis. The XY chart can be customized with your choice of trace lines. You can plot on both an XY chart and a Smith chart as well as view the data in tabular format. Zplots is an Excel application that allows you to plot impedance and related data obtained from a variety of sources. Poking the red X with a stick generally does not help. Try pressing the 'Refresh' key on your browser. If they don't all load you may see a red X as a placeholder.

Resolving the Sign of X (applies only to VNA1 and miniVNA).
