R/l= Resistance pr. length in [Ohm/m] ~1 Q; n) Z7 O6 C, R% e6 Y
The lossless part can be described in three ways
2 l! ?* Z4 b% x1 [7 O2 S 0. Inductance L' in [mH/m] if Xopt=0 or in [ohm/m] if Xopt=power frequency: h# D9 @' d8 M% ^0 j w. _
Capacitance C' in [uF/m] if Copt=0 or in [uMho/m] if Copt=power frequency
2 b# d0 g7 ~: q- w8 R) K) j, V 1. Modal surge impedance in [ohms]; Z=sqrt(L'/C')
9 N) E- j$ k# u6 Z0 L* v9 L! J& a Modal propagation velocity in [m/s]; v=1/sqrt(L'*C')

Xopt. and Copt. are set in menu: ATP|Settings/Simulation.8 n# Q; A" n& w& H: K
The user can choose conductance modeling G=0 (the usual case) and G=R*C/L (distortionless)
. P/ w3 j# c, B! h, c. K0 c length= length of line in [m]
2 I5 I* }# D. j9 f x帮助里面的,说的够清楚了吧- y/ R$ @ [8 C) v5 D
Xopt在setting里面设置,如果用的是atpdraw的话 |
