Re: LTspice Question



Hi Ken,
I don't quite have it,
I'm plotting (v(in)) which is the voltage out of the signal generator
(with internal resistance) feeding a filter. The plot shows voltage
amplitude
and phase. If I right click and change (v(in)) to re(v(in)) then I still
need to do
something with im(v(in)). I either have improper syntax or I'm putting it in
the
wrong place.
If I get it right, what is the label on the left y axis? It seems to be
voltage I was
looking for ohms.
Maybe I need to plot something different from the start?
Thanks for working me through this,
Mike


Get the plot showing amplitude and phase.

Bring the cursor over the lets say V(n002) at the top of the plot

Right click and change what is plotted.

re(v(n002)) plots the in phase part of a voltage
im(v(n002)) plots the quaderature part.

To get both, you need to get the raw signal displayed again and edit the
second one.

Next you double (left) click the scale down the right side and tell it not
to plot phase.

Is it possible to graph R and X of a circuit?
Such as looking into a filter, instead of amplitude
and phase, could I graph R and X.
If yes, how?
