The lossless part can be described in three ways: B" c' S6 p8 x3 _9 Z4 ?+ }
0. Inductance L' in [mH/m] if Xopt=0 or in [ohm/m] if Xopt=power frequency5 X. n5 V2 A; ]% a; l2 X
Capacitance C' in [uF/m] if Copt=0 or in [uMho/m] if Copt=power frequency Z; I+ Q6 h1 [9 S. V

Xopt. and Copt. are set in menu: ATP|Settings/Simulation.
- c6 v& h" u0 x2 R: i The user can choose conductance modeling G=0 (the usual case) and G=R*C/L (distortionless)
- ~. j% I8 u. n length= length of line in [m]' u7 [! ~1 k0 P X
帮助里面的，说的够清楚了吧
' A9 H4 p8 e" C/ D1 RXopt在setting里面设置，如果用的是atpdraw的话 |
