oscilloscope can be helpful . but mostly worthless when U R dealing with ded set or without diagrams. and there are few things uU can do with oscilloscope. the Idal thing should be CMU 200 .

U cannot mesure it with oscilloscope, coz oscilloscope can mesure max 40MHz.
use spactrum analyzer or CMU200, or just replace it ( its better)

@lasa_dal,

The crystal frequency is in Kilohertz (32.768 KHz) and not in Megahertz. So the oscilloscope CAN measure it. This could also be checked on a multimeter with a frequency counter function or a stand alone frequency counter. I once was lucky to get a multimeter that goes upto 14MHz.
