Why Talk About Flat Impedance and Power Integrity?

Today’s power supply designs require new techniques and metrics, whether you are working with CPUs, FPGAs, DDR memory, or SERDES, noise matters. It’s not about the lowest impedance power supply but the right impedance power supply. Learn more at EDI CON (http://www.ediconusa.com/) and DesignCon (http://www.designcon.com/) and from these videos: https://www.youtube.com/user/Picotest1.

New Semi-Floating Differential Amp Solves PDN 2-Port Shunt Thru Measurement Hurdle

December 19, 2017, Phoenix, Arizona: Picotest.com, a leader in high resolution test and measurement equipment, has released a new solid-state Semi-Floating Amplifier (SFA), or ground loop isolator, that provides the BEST isolation for low impedance measurements. The new amplifier eliminates the DC ground loop from DC up to 800MHz. The high frequency response supports the 2 Port Shunt Thru impedance measurement required for Power Distribution Networks (PDNs). The amplifier works with network analyzers and oscilloscopes. The J2113A removes the ground loops associated with VNAs and Oscilloscopes which frequently occur in power…

New Ways to VRM Modeling & Decoupling – Thursday, November 3rd, 2016, 08:30 – 17:00

REGISTER HERE September 6, 2016: The Voltage Regulator Module (VRM) is a fundamental element in the Power Distribution Network (PDN) with system level consequences heavily impacting Power Integrity. Very few, if any, manufacturers provide high fidelity VRM models and much of the data required to construct your own model is not published. In this compact one day workshop you will be guided through all measurement and simulation steps required to generate a measurement based VRM model. Each theory step is followed by practical measurements performed in small groups. This workshop introduces a measurement based,…

Picotest J2160A Probe Adapter Featured in Power Electronics Products of the Week

August 4, 2016: Picotest has released a new probe adapter for the popular Keysight E5061B vector network analyzer. The Picotest J2160A Probe Adapterprovides a low noise, compact solution when using the E5061B T/R ports in a 2-port shunt thru measurement. The T/R ports are desirable for low frequency 2-port measurements, since these ports are semi-floating, allowing low impedance measurements without the use of a coaxial common mode transformer such as the Picotest J2102A. The floating ports allow milliohm measurements even at very low frequency and up to the 30MHz range of the T/R ports. The current solution uses…

Picotest Releases New Probe Adapter for the Keysight E5061B ENA

January 12, 2016: The J2160A Probe Adapter provides a low noise, compact solution when using the E5061B T/R ports in a 2-port shunt thru measurement. The current solution uses a resistive 6dB port splitter combined with coaxial cables to support this measurement. The J2160A is a slim profile adapter, converting the three E5061B BNC ports to two BNC ports for the 2-port measurement. The 6 dB resistive port splitter is included internal to the adapter so no external splitter or cables are required. The short connections are neater, consume less bench…
