(15C) Transmission Line (calibration & impedance)

[SlideRule]

An extract from Reflections III Transmission Lines and Antennas, Chapter 15 Computer Programs for Impedance Matching (pg 15-1), Sec 15.4 Programs for Hewlett-Packard Hand-Held Calculators (pg 15-7), Program HP1 (pg 15-24) & PROGRAM HP2 (pg 15-26).

"If you prefer to use a hand-held calculator instead of a computer for solving the transmissionline problems, two calculator program listings are included that can substitute for the TRANSCON and LINTRNSM computer programs. They are written in reverse Polish notation for Hewlett-Packard calculators. I use HP-15C and HP-34C calculators. Other models may have different register designations than those shown in Programs HP1 and HP2 …

Program Listing for TRANSMISSION-LINE CONSTANTS
The program yields transmission constants line length t in electrical degrees, attenuation in dB, and characteristic impedance Zc from line-input impedance measurements with the line terminated with impedances Zsc and Zoc …

Program Listing for TRANSMISSION-LINE IMPEDANCE TRANSFORMATION
The program transfers a known impedance at one end of a line to the unknown impedance at the other end …"
