LT Spice noise

Hi, would someone try this for me?

The syntax is incorrect (the param should be V(AMP) and not AMP) but on my PC, it doesn't complain, it crashes. I'm running rev 4.19I.

Seems to crash because of AMP has no load. Adding a resistor brings up the noise command syntax error. Does not really answer your question however.

I sent in a bug report, using the link in HELP/About. About an hour later, Mike Engelhardt answered me... from Moscow! He says he'll fix it in the October release.

Now that's tech support!

Particularly considering the maintenance fee. ;)

Engelhardt will fix LTspice so it will not crash, but will simply announce that a .NOISE analysis _requires_ a .AC analysis statement as well. RTFM >:-} ...Jim Thompson
