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…

Rohde & Schwarz ZNL VNA Gains Non-Invasive Stability Measurement

July 10, 2019 Phoenix, AZ: Picotest.com, a leader in high resolution test and measurement equipment, has announced the availability of new software that brings the unique non-invasive stability test capability to the Rohde & Schwarz ZNL and ZNLE vector network analyzers. The software add-on, available now for new or existing customers, allows the instrument to perform non-invasive stability margin (“NISM”) measurement. NISM is an alternative to a Bode plot measurement that allows the user to test circuit or filter stability even when the control loop is not accessible. It determines…

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…

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…
