Solving Power Integrity Test Challenges

Steve Sandler (Founder and CEO, Picotest)

Location: Room 203

Date: Wednesday, January 29

Time: 3:45pm - 4:25pm

Track: Sponsored Session

Vault Recording: TBD


Power Distribution Networks (PDNs) must provide many low-noise DC
power rails for sensitive loads such as microprocessors, DSPs, FPGAs and
ASICs. Higher current, lower voltage power rails impose tighter voltage
noise requirements. The need for greater efficiency requires many more
voltage rails. All of these demands along with higher channel frequencies
and edge rates put pressure on the design from SI, PI and EMI
perspectives.Power integrity measurements validate that the voltage power rail noise
voltage meets the specifications and assures that the noise doesn't
degrade signal integrity.

By attending this session, you will learn about the major noise sources in a
mixed signal application and how to:
• Accurately measure (2-port/3-port) impedance of a power distribution
network (PDN) and its sub-systems using a scope
• Analyze high frequency complex ripple in the presence of low tolerance
DC Power rails
• Automate time sequencing testing for multiple rails simultaneously
• Use your scope for many other critical tasks such as TIE Jitter, Frequency
Response, and TDR
• Perform various VNA functions in your scope
