Why is it important to use an oscilloscope with more bandwidth than my device under test?
回答：
Without adequate bandwidth, your oscilloscope will not be able to resolve high-frequency changes. To calculate the oscilloscope bandwidth needed for your application, simply multiply the highest-frequency component of the signals you will be working with by a factor of five. For example, if your bus frequency is in the 800 MHz range, you may need an instrument with 4 GHz bandwidth or higher. This “5 times rule” will give you less than ±2% error in your measurements – typically sufficient for today’s applications.
