Power Integrity for I/O Interfaces: With Signal Integrity/Power Integrity Co-Design
by Vishram S. Pandit, Woong Hwan Ryu, Myoung Joon Choi
Chapter 9. Measurement Techniques
This chapter addresses frequency domain and time domain measurement techniques for power integrity and signal integrity. The measurement of S-parameters constitutes a vital component of power/signal integrity design verification for high-speed I/O interfaces. Typically, S-parameters are measured with a Vector Network Analyzer (VNA) that calculates input/output reflections and transmission by sequentially applying signals at various frequencies and recording the response of the Device Under Test (DUT). The resulting data depicts a set of measured values as a function of frequency. On the other hand, an oscilloscope, a measurement instrument used for Power Delivery Network (PDN) noise measurements and signal jitter ...
