Gravitational waves were first proposed by Henri Poincaré in 1905 and further described in Albert Einstein’s 1916 General Theory of Relativity. Gravitational Waves are powerful perturbations of the space-time continuum. However, the sources of gravitational waves we know about are enormously distant and therefore faint by the time they reach earth–like EM radiation, their intensity […]

Economical 7.5-GHz spectrum/VNA targets signal distortion, modulation, spectrum purity, frequency stability, crosstalk distortion parameters
The Siglent SVA1075X Spectrum/Vector Network Analyzer is a powerful tool with reliable automatic measurements for measuring the performance of RF circuits and networks such as amplifiers, filters, attenuators, cables, and antennas. With a wide frequency range from 9 kHz to 7.5 GHz, the SVA1015X analyzer delivers reliable automatic measurements with its built-in tracking generator and […]
Testing vulnerabilities in programmable logic controllers
Had you examined the controls handling automotive assembly lines before the mid 1970s you would have found cabinets full of relays, cam timers, drum sequencers and hardwired controllers. All these controls had to be swapped out or modified to handle line retooling during a model-year change. To reduce the cost of such changeovers, General Motors […]
Software simplifies design-for-test tasks in IC development
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 […]
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 […]
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 […]
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 […]
Rugged ATR chassis for VITA 48.4 features liquid flow-through cooling
A new rugged ATR chassis compliant with VITA 48.4 for liquid flow-through (LFT) cooling includes a new backplane designed for data rates up to 10 Gbps and can handle 300 W per slot. This enables the system to accommodate the intense thermal management needed in high-density embedded computing systems. The new chassis offers several other […]
NI CEO: COVID-19 on day one
NI CEO Eric Starkloff’s first decision was what to do about COVID-19 the night before he took over on February 1, 2020. Since then, he’s seen the opportunities in communications resulting from the pandemic. How would you like to take on a new leadership role just as a pandemic takes hold? That’s what Eric Starkloff […]
