Hello,
I've circuit based on 555 timer which should generate 40kHz (50% DC) square wave.
But Multisim simulate 26.367 Khz only.
Circuit calculated by "Tools/Circuit Wizard/555 Timer Wizard/" and verified with datasheet.
This circuit assemblied on real maket board and works fine.
Multisim version is 10.1.1
So, what's wrong here?
Thanks,
Sergey

Hi,
I built the circuit using the shown component values and I was able to get the circuit to produce the right reading by changing the time step(TMAX) from 1e-5sec to 1e-8 sec, this setting is under Simulate>>Interactive Simulation settings. By reducing the time step you are telling the simulator to take more samples and gave and more accurate reading.
