Cable Characterization Calculator

Enter Measured Resonant Frequency, Capacitance and Cable Length

 Cable length (ft)
 Resonant frequency (MHz)
 Total capacitance (pF)
 Ω Impedance = Propagation Delay / Capacitance
 Propagation delay (nS/ft) = 1 / Resonant Frequency
 Capacitance (pF/ft) = Total Capacitance / Cable Length
 Inductance (uH/ft) = (Impedance2 * Capacitance) / 1,000,000
 Velocity of propagation (%) = Speed of Light / Propagation Delay

Coax Impedance Calculator

 Dielectric constant
 Inches outside diameter center conductor
 Inches inside inside diameter of shield
Ω Impedance

Get Impedance from Rho

 Rho Value: A number  between -1 and 1
 System Impedance (default = 50 ohms)
Calculated Impedance
