for the HP 15C
ZS11 - 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]
RI	: |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
