Hello, I am a beginner small circuit and high-frequency projects for amplifier equipment and driver circuits, and I am in need of a used or broken oscilloscope. I have broken several devices with the wrong frequencies and i am in need of one of these so I will be able to monitor the frequencies of my devices. Preferred specifications; Dual Channel,

USB or PCI based data acquisition and display systems would cost you more than a benchtop oscilloscope. Try in your circle for any abandoned or old cathode ray tube based oscilloscopes from Industries which should serve your purpose. I assume you aren't looking for any high frequency applications.

Say I have a noise free square wave signal of 1 khz frequency and 5 v amplitude. The signal passes through some optical receiver and the shape of the signal becomes slightly distorted with some noise in it. I have a digital oscilloscope that has FFT. How can I use this FFT to detect the frequency of the noise so that I can separate the noise from t

Or alternatively use a 555 timer with a variable resistor to adjust frequency. Again feed the output to the MOSFET. Perhaps,
