I'm trying to get an idea of the time response of a laser-gate I'm building; so, I wanted to do some basic simulations in LTspice based on this thread:
Attached below is my circuit and voltage response at the oscilloscope.
I'm confused because I figured the time response was going to be on the order of RC, ~10 ms for the given scope impedance and filtering cap, whereas this simulation seems to suggest it's only a few microseconds.
Is my understanding of the time response wrong? Or am I doing this simulation incorrectly? Thank you.
