New J2161A Brings 2-Port Shunt-Through Impedance Measurement to Scopes

August 7, 2019 Phoenix, AZ: Picotest.com, a leader in high resolution test and measurement equipment, has released the J2161A, 2-Way Wideband Active Splitter. This accessory enables the 2-port shunt-through impedance measurement on oscilloscopes. Traditionally, this measurement has been performed on Vector Network Analyzers (VNAs) or Frequency Response Analyzer (FRAs). But oscilloscopes, such as the Tektronix Series 5 and 6 scopes, offers a software add-on (5/6-PWR software) to enable this measurement in the frequency domain. The 2-port measurement is the ‘Gold Standard’ test for Power Distribution Network impedance in the microohm…

NIST Traceable Certification for 10.5GHz TDR in a Flashdrive

We asked a 3rd party calibration lab to provide NIST traceable performance data for our new J2151A PerfectPulse Fast Edge Signal Generator.  Their data confirms our 10.5GHz published edge speed.  The test data also confirms the 500mV and the flatness at 1GHz and 2GHz are 0.25dB and 0.37dB respectively. For more information please see https://www.picotest.com/products_J2151A.html

New Fast Edge TDR in a Portable Package Supports PCB Coupon Testing and Instrument Calibration

June 6, 2018 Phoenix, AZ: Picotest.com, a leader in high resolution test and measurement equipment, has released a new, low cost, pocket-sized, fast edge signal generator and TDR in one convenient package. “Such a high speed, precise TDR/TDT has never before been available in this portable form, requiring only a USB power source, and at this price point,” according to Steve Sandler, Picotest CEO. The PerfectPulse signal generator provides an ultra-fast, square, 32ps edge pulse. The -500mV, 50 Ohm output signal (trimmed for accuracy) is very square, without overshoot or…

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.

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…

Characterizing and Modeling Switch Mode Power Supplies (Mar 15)

Original air date: March 15, 2017   Johnnie Hancock Oscilloscope Applications Manager Keysight Technologies Steven Sandler Managing Director Picotest Why this Webcast is Important: Whether your power supply designs are based on switch mode or linear technology, there are many reasons why you should characterize the frequency response of your power supply designs. Two reasons are to better to understand the stability and noise immunity under various load change conditions based on an existing design. Another good reason is to gain the missing information required to create or improve a…

How Does a Prototyping-Only Approach Impact Product Design?

Article by Sam Davis | Power Electronics One in 10 design engineers still rely on purely physical prototypes, potentially adding significant, unnecessary costs to their designs, according to engineering surveys. Many engineers rely solely on prototyping their designs to produce reliable and cost-effective products. However, some form of simulation along with prototyping can actually improve product designs. So it begs the question: “How should engineers decide on the optimum amount of prototyping and simulation?” One in 10 design engineers still rely on purely physical prototypes, potentially adding significant, unnecessary costs to their designs.…
