An automation-ready cable and harness test system now has an environmental sensor option incorporating the Dracal PTH200 sensor. Of particular interest to medical and defense applications, this option provides automatic measurement and reporting of environmental test conditions (temperature, relative humidity, pressure) alongside electrical function data for the cable, harness, or backplane under test. This option […]

Power supply ICs come in rad-hard plastic packages
Texas Instruments announced an expansion in its portfolio of space-grade analog semiconductor products in highly reliable plastic packages for a diverse range of missions. TI developed a new device screening specification called space high-grade in plastic (SHP) for radiation-hardened products and introduced new analog-to-digital converters (ADCs) that meet the SHP qualification. TI also introduced new […]
EMI gaskets designed for MIL-DTL 83513 connectors
Micro-D Connector Gaskets are specifically designed to be used with MIL-DTL-83513 microminiature connectors. These specialized gaskets eliminate any unwanted gaps between the connector and I/O surface points and offer a shielding effectiveness of 80-115 dB. The micro-D connector gaskets are available in 9-pin through 100-pin sizes and will fit either plug or socket versions of […]
MCU-compensated XOs feature high stability, low power consumption
The QT2020 Series of microcomputer compensated crystal oscillators provide exceptional temperature stability (up to ±20ppb at -40 to +85°C) while consuming a maximum of 90 mW. The QT2020 small form-factor package weighs just 50 gm, compared to comparable oven-controlled (OCXO) units weighing 100 gm or more. This significant improvement in size, weight, and power (SWaP) […]
RF power sensors cover –60 to +20 dBm, 50 MHz to 50 GHz range
The new R&S NRPxxP RF sensor family includes units with a measurement bandwidth up to 30 MHz, a new improved design and an extended frequency range. The three-model family covers frequency ranges from 50 MHz to 18 GHz, 50 MHz to 40 GHz, and a new top model for 50 MHz to 50 GHz. R&S […]
Can I park in one of your Lagrange points?: Part 3
Analysis and insight from an 18th-century mathematician were used to place the James Webb Space Telescope in a “parking spot” optimally suited for its imaging, communication, and solar-power needs. There’s more to the n-body story and Lagrange’s work. All planets orbit the Sun in an oval, as characterized by Kepler’s Laws, so there is a […]
Development kit covers SOSA aligned chassis management
Pixus has announced a new development kit for OpenVPX/SOSA Hardware Management Card (HMC). The SHM300-10 development kit is currently shipping to customers as an early prototyping tool for future deployable versions of Pixus’ SHM300 SlotSaver mezzanine-based chassis manager. The SHM300 HMC is a SOSA-aligned “Tier 3+” board designed for MIL rugged applications on aircraft, shipboard, […]
Can I park in one of your Lagrange points?: Part 2
Analysis and insight from an 18th-century mathematician were used to place the James Webb Space Telescope in a “parking spot” optimally suited for its imaging, communication, and solar-power needs. Lagrange’s analysis was an analysis of the three-body problem and provided insight into the conditions under which it could be solved analytically. The five Lagrange points, […]
Can I park in one of your Lagrange points?: Part 1
Analysis and insight from an 18th-century mathematician were used to place the James Webb Space Telescope in a “parking spot” optimally suited for its imaging, communication, and solar-power needs. You’ve undoubtedly followed the stunning success of the James Webb Space Telescope (JWST), launched in December 2021 (Figure 1). It is now about 1.5 million kilometers […]
Controller monitors hydraulic, electrical test stands
The latest version of the Moog Test Controller is more compact than earlier models and meets the different needs of test lab managers without the use of additional hardware. Moog’s engineers have also designed the new controller with an EtherCat bus, which provides the flexibility to meet future developments and the adaptability for future testing […]
