Impedance to scattering parameter conversion

for the HP 15C
Z→S₁₁ - Impedance to scattering parameter conversion

Usage

[GSB][1]

Input

X  :  Z  - The complex impedance [Ω]
R₀ :  Z₀ - Characteristic impedance  [Ω]

Resources used

R₀	: Z₀ - Characteristic impedance  [Ω]
R_I	: |Γ| - The magnitude of the reflaction coefficient 
LBL 1	: entry point

Output

T : S₁₁  - the complex one port reflection coefficient
Z : VSWR - voltage standing wave ratio
Y : RL   - return loss [dB]
X : S₁₁  - the complex one port reflection coefficient
