1.What is output type of quartz crystal we connect across microcontroller? Is it sine, square, clipped sine?
2. I have 16Mhz crystal connected across(MCU) with two capacitors to GND from each leg. MY DSO is 60Mhz & probe is at 10x
3. I tried probing across one leg of probe at Crystal In & another at cyrstal output. It seems sine to me? Or is due to my DSO is less freq? I think DSO should be atleast 5 times for square & 10 times for sine wave?
4. Three probe I tried:
a) One probe at XTIN & another at XTout
b) One probe at XTIN & another at GND
c) One probe at XTOUT & another at GND
