Basic Waveform Measurement
So I hooked up the oscilloscope to the function generator with a coaxial cable into channel 1 of the oscilloscope. The type of connectors used were BNC. I almost understand the function generator thanks to Lorenzo and Koch, and I get the screen on the oscilloscope to create some cool periodic functions.
I created a sine pulse at 200 Hz at about medium amplitude. The oscilloscope measured it to be 196 Hz and to have an amplitude of about 7 V. Changing the shape from a sine to different jagged periodic function didn't change the amplitude or frequency measured by the oscilloscope. Very low frequencies could be measured (down to .1 Hz), but high frequencies, once I zoomed in enough, created a jittery fuzzy curve. The stepwise function at high frequencies didn't create sharp bends. Maybe the crappy wire setup I had caused this. Also, at high amplitude, DC offset did not work in its full range because the function generator was maxing out.
