Four Tips for Making Better Power Rail Measurements
Power distribution networks, or PDNs, have become a key technology focus in electronic design. Because PDNs are routed to all devices that need power, any noise or transients on power rails propagate throughout the system. Hence, noise and coupling on power rails is often the number one source of system jitter. Power integrity measurements have become much tougher to accurately measure, but this application note will discuss four key tips to help you accurately test power distribution networks.
