2-Port Shunt-Through Impedance
PDN Measurement for Power Integrity
The 2-Port Shunt-Through impedance measurement is the Gold Standard for PDN testing and Power Integrity assurance. Power Integrity assessment and optimization is an essential element in today’s designs.
It is critical that your power supplies, printed circuit boards, and decoupling be properly designed in order to achieve flat impedance goals. Commonly applied “Rules-of-thumb” generally don’t work well in high speed circuits or other sensitive applications.
Design assurance, optimization and troubleshooting all require accurate low impedance measurements. Whether you are modeling components, testing power supply output impedance, assessing target impedance, or looking to manage PDN resonances, Picotest has a 2-port testing solution for you. Look below for testing solutions and product information.
What is a ground loop and why does is need to be broken.
