Cable Characterization Calculator

Enter Resonant Frequency, Capacitance and Length
Enter cable length (Feet)  
Enter resonant frequency (MHz) Measured with a 2 port VNA
Enter total capacitance (pF) Measured with a LCR meter
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
Enter dielectric constant
Enter center conductor diameter (Inches)
Enter shield inside diameter (Inches)
Impedance

Dipole Antenna Calculator
Enter Frequency in MHz
Enter frequency in MHz
Length 1/4 Wave (Meters)
Length of each leg of the Dipole (Feet)
Length of each leg of inverted "V" (Feet)

Frequency to Wavelength
Enter Frequency (MHz)
Enter frequency in MHz
1 Wave length (Meters)
1/2 Wave length (Meters)
1/4 Wave length (Meters)
   

SWR Calculator
Enter Power in Watts
Enter power forward (Watts)
Enter power reflected (Watts)
SWR

Calculate Risetime from Frequency
Enter frequency in Hertz. Example: 20 GHz = 20e+9
Approx. TDR Risetime (10/90) (Seconds)

Calculate Speed from Time & Distance Calculator (24 hour format)
Time calculator under construction
Enter Start Time (hh:mm:ss)
Enter End Time (hh:mm:ss)
Calculated Walk Time in Minutes
   
Enter Time in Minutes
Enter Distance in Miles
