Hello everyone
I am using Proteus Issis and I can't seem to show the pulsed output of an 555 chip with a simple 2 resistor and 1 cap in a simple astable mode. I can't show the waveform on the oscilloscpe in Issis. Any ideas
Thx in advance
Francisco
 

Firstly, make a ZIP archive with the DSN file.
Below the text box where you write the reply, there is a button "Manage Attachments". Click it. In the window that pops up, press "Add Files". Click "Select Files". Then select the ZIP file. Then post the answer.
 

Thx again. I should mention that I had the same problem with the 555 timer put this file is an Op-Amp TL 072 functioning at 3000 to 1000 kilo hertz and I can not see the same wave form that I see on my personal oscilloscope. I should be seeing a sine wave and all I see is a straight line.
Thx again for your very quick reply

Can you see a sine wave on your oscilloscope when you make the circuit in real life?
