R/l= Resistance pr. length in [Ohm/m]
8 f$ f+ G% A' j The lossless part can be described in three ways
! n- k! j/ ~4 u+ o 0. Inductance L' in [mH/m] if Xopt=0 or in [ohm/m] if Xopt=power frequency" b: X: \1 W/ c( i3 W

1. Modal surge impedance in [ohms]; Z=sqrt(L'/C')
: A- C! i8 \4 `5 S. v `1 ^$ i Modal propagation velocity in [m/s]; v=1/sqrt(L'*C')

Xopt. and Copt. are set in menu: ATP|Settings/Simulation.- U8 s q! e1 {3 r
The user can choose conductance modeling G=0 (the usual case) and G=R*C/L (distortionless)
* k+ I5 } W* x4 s6 j2 y length= length of line in [m]

Xopt在setting里面设置,如果用的是atpdraw的话 |
