[Help-gnucap] AC circuit analysis

[Evgeni Dobrev]

Hi all,

I have the following circuit:

AC VOLTAGE ADDITION   
v1 1 0 ac 15 0 sin      
v2 2 1 ac 12 35 sin
v3 3 2 ac 22 -64 sin 
r1 3 0 10k

The list command in gnucap results in:

V1  1  0  SIN  offset= 0.  amplitude= 1.  frequency= NA  delay= 0.
damping= 0.  AC   0.
V2  2  1  SIN  offset= 0.  amplitude= 1.  frequency= NA  delay= 0.
damping= 0.  AC   35.
V3  3  2  SIN  offset= 0.  amplitude= 1.  frequency= NA  delay= 0.
damping= 0.  AC  -64.
R1  3  0  10.K

Why can't I see the phase offsets? 

The command sequence:

.print ac v(3) vp(3)
.ac lin 1 60 60

produces in gnucap:

#Freq       v(3)       vp(3)
 60.        29.        180.

and in spice:

freq          v(3)        vp(3)       
6.000E+01     3.050E+01  -6.094E+01

What am I doing wrong?


Thanks in advance,

evgeni
