No reading on the frequency counter

I'm not getting a reading on the frequency counter when I wired the clock signal onto it. There's just one input to the counter, so I wired a clock and try to get a reading. All I see are the dashes. Is there something else I need to do? thank you.

Hi,

 

You can configure some parameters in the pop-up window of the instrument. Trigger Level, sensitivity and AC or DC Coupling. You can try to set these based on your circuit.

 

If you want us to take a look at it, please post the circuit.

 

As an alternate, you can also see the freq in the measurement probe. Go to Simulate -> Instruments -> Measurement Probe and click on the net (wire) where you want to check the frequency.

 

Hope this helps.

Regards,

Tayyab R,

Sorry for the kick, but I seem to have the same problem.

 

I've build a LM324-based pulsegenerator and it's doing what's it was made to do, but the frequency counter is not detecting the pulses. The oscilloscope and measurement probe are detecting the pulses without problems.

 

Changing the settings on the frequency counter didn't resolve the problem. See attached picture for the circuit.
