How to add EARTH symbol in LT Spice IV?

Thank you...wintermute...but i dont know how to measure slew rate of amplifier...i im reading in wikipedia...but dont understand.

I'm afraid I don't know either, but aparatussonitus posted some info in post number 27. Basically that looks like a square wave to me, and I'm guessing that the point where it stops looking like a square wave (ie frequency) will be the point that the slew rate is determined, however It's not something I'm familiar with simulating or measuring so I'm not really sure.

Here is PULSE as suggested to try...i im simulating and are getting downstep amplitude from
5.7V down to undefined values...🙁

Here is screen shoot what i have try to put PULSE generator at input. What i was doing wrong?

Pulse source is a DC signal, and you are blocking it with C1...lose it😉
