ZPlots - Plot Impedance Data
Zplots uses Excel's charting capabilities to plot impedance data obtained from a variety of sources, including the W5BIG AIM4170 Antenna Analyzer, the N2PK Vector Network Analyzer, and several different antenna modeling programs.
Experiment with transmission lines. Watch impedance points change on a Smith chart as you quickly vary input parameters using spin buttons. Plot matched line loss versus frequency.
L. B. Cebik, W4RNL, developed an algorithm for calculating the dimensions of a Moxon Rectangle antenna. He asked me to write this small program incorporating his work and I was happy to oblige.
Have you ever wondered what these four things have in common? No, of course not, me neither! But perhaps you have wondered why a Smith chart has such strange grid lines. Believe it or not, there is a logical progression from Speedometers to Smith charts that will make the Smith grid crystal clear.
