Re: How to make a simple freq. analyzer with a old oscillosc
For the experimental or know how purposes, it is good to make such equipment. But my experience and logic says, always buy basics or advanced equipments (for your measuerment needs), even if you are able to build them. Because these are build by professionals and have very costly reference tools to calibrate them. So, for any professional work one should do that. For the cost issues, Yes, these are comparitivly costly. But one can use some organisation equipments on their site.
