ZL4AI replies: Yes you can do a lot with SP1 Files. The following software allows directly reading:
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 show "reverse" scale (see note below)
Phase (deg) - Reflection coefficient angle
% Reflected Power
Q - Quality factor, |Xs| / Rs
Rp - Resistance, parallel form
Xp - Reactance, parallel form
Ls (?H) - Equivalent inductance for series Xs, both positive and negative
Cs (pF) - Equivalent capacitance for series Xs, both positive and negative
Lp (?H) - Equivalent inductance for parallel Xp, both positive and negative
Cp (pF) - Equivalent capacitance for parallel Xp, both positive and negative
