The Tessent Streaming Scan Network software for the Tessent TestKompress software includes embedded infrastructure and automation that decouples core-level DFT (design for test) requirements from the chip-level test delivery resources. This enables a no-compromise, bottom-up DFT flow that can dramatically simplify DFT planning and implementation, while reducing test time up to 4X. With full support […]
Test and Measurement Tips
Debug tookit for DDR5 and LPDDR5 handles 6,400 Mb/sec data rates
A DDR5 Debug Toolkit runs on SDA 8 Zi-B and LabMaster 10Zi-A oscilloscopes. The DDR Debug Toolkit now supports DDR5/LPDDR5 for test, analysis and debug of the entire DDR design cycle. Features include automatic Read/Write burst separation, bursted data jitter analysis, eye diagram mask tests, DDR-specific measurement parameters, and seamless integration with the HDA-125 High-Speed […]
OpenVPX backplanes designed for horizontal-mount enclosures
New OpenVPX backplanes are designed for horizontal-mount enclosures. The horizontal-mount backplanes can be placed into 1U-4U tall 19-in rackmount OpenVPX enclosures. They provide enough space to have three 3U slots or one 3U and one 6U slot side-by-side. So, a wide range of configurations and size options are available. The backplanes are typically designed to […]
The difference between noise and jitter
Electronic noise and jitter are closely related phenomena, but they are not the same. While noise typically manifests as amplitude distortion, jitter pertains to timing of digital signals. Either of them can be caused by outside interference or internal sources. Noise can be seen in an oscilloscope time domain display as a noticeable thickening of […]
PC-based automotive scope adds EV test diagnostics
The new PicoScope 4425A EV Oscilloscope Kit is designed to provide a comprehensive diagnostics capability for all types of vehicles with electric (BEV, MHEV, PHEV, Fuel-cell) and internal combustion (diesel, gasoline, LPG) powertrains. It provides service shops with a futureproof system for analyzing vehicles with high-voltage batteries and electric motor systems. In combination with the […]
Isolated scope probes feature high bandwidth, dynamic range, CMRR
The second-generation IsoVu Isolated Oscilloscope Probes, called the TIVP Series, extend the applications for isolated probe technology to the entire power system design market with a smaller size, improved ease of use, and enhanced electrical performance. Making accurate measurements on high-speed ungrounded systems can be nearly impossible using traditional differential probes. Engineers working with wide-bandgap […]
Bi-phase modulators encode RF carriers via 2PSK
A new line of bi-phase modulators covere broad octave frequency bands from 0.5 to 40 GHz. These models use TTL logic to phase-modulate data onto an RF carrier signal using two-phase shift keying (2PSK). Useful applications include military and commercial communications systems, microwave radio, radar, high-data-rate test & measurement, serial data transmission and wireless base […]
Common-mode differential probes excel at 48-V GaN power conversion work
New DL-HCM probes from Teledyne LeCroy target 48-V GaN Power Conversion. They are available in 500 MHz and 1 GHz bandwidth and feature 60 V of common-mode and 80 V differential input range. The 60 V of common mode is well suited for handling any float of the battery and bulk/absorption voltage during charging, while […]
New book covers EMC troubleshooting with test instruments
A valuable 180-page book called “Create Your Own EMC Troubleshooting Kit: Essential Tools for EMC Troubleshooting” by EMC guru Ken Wyatt is the first volume in Wyatt’s EMC troubleshooting series. It covers the benefits of creating a personal EMC troubleshooting kit and also defines which products to include. Individual chapters name suitable spectrum analyzers, near-field […]
PXI switching modules handle heavy ac and dc loads
A new high-power relay PXI module provides the industry’s highest switching capacity in the smallest footprint for a solution based on electromechanical relays. Occupying a compact single PXI slot form factor, the model 40-166 is available with SPST, SPDT or SP4T switching configurations. It uses power relays suitable for switching loads up to 20 A […]
