Time domain simulation of sine wave 50KHz signal for me does not work

I am using micro-soft edge version 87 (64 bit) browser. Seems to work great. but the public circuit above with 50KHz sine wave input across 100.1 K Ohm analyzed at step times of 20 us for 600 us gives a pretty wierd result. definitely not a steady 50 KZ signal. What am I doing wrong?

When results are weird and wonderful the first thing to look at is step time. I set the step time to 0.1e-6 and stop time to 50e-6 and the result at "B" looks perfectly logical. I don't know what you were doing with SW1 and "A" so I didn't chase it

Got it, Thanks! sine wave works and then I put in a 100KHz voltage source, took out the switch and got the triggers every ten micros at A that I wanted.

Glad you got what you wanted. Have you looked at the laplace block? With the appropriate transfer function this would get the same results much more simply.
