hello!
i am using the following probes for my sound card oscilloscope.
![probe.jpg probe.jpg](https://www.edaboard.com/data/attachments/8/8179-ba193e8dcbc53e4859efc740dc0b5b64.jpg)
it is giving me the following results from pic16f819 50 hertz oscillator. the frequency counter shows 49 hertz. because it is not complete 50 hertz![Stick out tongue :p :p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

but i think the following schematic may improve the input signal and save my sound card from surges.
