The output voltage problem of NE555

[Luness]

I'm trying to make a simple astable circuit. It should be one of the easiest ones in history of electronics, but I can't figure out what's wrong with my design:

The output voltage remains too low. About 1.5 V peak to peak.

(For my application this is less important, but maybe it could be useful to note also that the calculated frequency differs from the real one of about 30 KHz.)

I tried a different power supply and also a different NE555 IC. Could someone please explain to me why the voltage is so low?

Hello, since it sounds like the frequency you are generating and the output voltage is incorrect, I'd check to make sure you circuit is properly set up and that all of the components are their expected value. I didn't check the circuit using one of those calculators for astable 555 timers online, so I can't confirm if the values are correct.

Also, this may not be the best forum for general circuit design. This board is for questions regarding counter/timers while working with National Instruments' products.
