zplots 1.6 publisher's description
zplots is a handy tool designed to enable you to plot impedance and related data obtained from a variety of sources. you can plot on both an xy chart and a smith chart as well as view the data in tabular format.
the xy chart can be customized with your choice of trace lines. frequency (in mhz) is always shown on the x axis. on the primary (left side) or secondary (right side) y axis you can plot:
* swr - standing wave ratio
* rs - resistance, series form
* xs - reactance, series form
* zmag - impedance magnitude
* theta (deg) - impedance angle
* rho (mag) - reflection coefficient magnitude
* rl (db) - return loss, plotted as a negative number to simulate "reverse scale"
* phase (deg) - reflection coefficient angle
* % reflected power
* q - quality factor, |xs| / rs
* rp - resistance, parallel form
* xp - reactance, parallel form
* ls (µh) - equivalent inductance for series xs, both positive and negative
* cs (pf) - equivalent capacitance for series xs, both positive and negative
* lp (µh) - equivalent inductance for parallel xp, both positive and negative
* cp (pf) - equivalent capacitance for parallel xp, both positive and negative
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.
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. on the secondary (right side) y axis you can also choose "(none)" to indicate no secondary plot line.
a mini-smith chart is shown on the same sheet with the xy chart. 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). alternatively, on the excel menu you can select view | zoom and choose a magnification level less than 100%.
