A central concept in magnetism is the domain, discovered in 1906 by Pierre-Ernest Weiss. He theorized that in any magnetically permeable material, a large number of mostly microscopic regions existed as separate walled-off entities. In each of these entities, called domains, the atomic moments align in parallel when magnetized. But the alignment of individual domains […]

Ultrahigh-speed cameras include back-side illumination
Two new models in the Ultrahigh-speed performance line of Phantom cameras feature a breakthrough CMOS sensor with back side illumination (BSI). The new T3610 and TMX 5010 cameras sustain their image throughput with optimized light sensitivity for high frame rates and sub-microsecond exposures. Joining the T-Series platform, the Phantom T3610 achieves significantly higher frame rates […]
Raspberry Pi for DAQ
Though they are more closely associated with the maker space, Raspberry Pi boards can be effective at handling stringent industrial measurements. Steve Radecky, Measurement Computing Corp. Originally designed to be a cheap, almost disposable computer, Raspberry Pi was created to get kids interested in programming. Since its introduction in 2012, Raspberry Pi has become the […]
Optical spectrum analysis module is hot swappable
The mOSA Module adds optical spectrum analysis to the VIAVI Multiple Application Platform (MAP) Optical Manufacturing Test system. The mOSA complements existing VIAVI solutions for optical power measurement, switching and signal conditioning, and test automation, further enhancing the industry's most comprehensive test portfolio for development and manufacturing of optical communications technology. The new MAP mOSA […]
Optical power meters, time-domain reflectometers optimized for fiber testing
New optical power meters, fiber characterization modules, and an enhanced Optical Time Domain Reflectometer (OTDR) solution help reduce costs, improve quality of service, minimize downtime and speed time to revenue. New and enhanced elements of the VIAVI fiber portfolio include: • OTDR 2.0 – The all new VIAVI OTDR solution, redesigned to deliver faster, more […]
Measuring the Hall effect
The Hall effect, first described by Edwin Hall in 1879, results in an electrical output when a thin metal plate is immersed in a magnetic field of sufficient strength. The magnetic field must be perpendicular to an electrical current conducted through the plate. The Hall effect voltage potential depends upon the strength of the magnetic […]
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 […]
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 […]
Versatile development enclosures support SOSA, OpenVPX
Versatile backplane/chassis configurations are geared for 3U and 6U OpenVPX and SOSA development. The versatile development enclosures start with a line of single-slot power and ground backplanes in various 3U and 6U configurations. This includes VITA 65 (standard VPX), VITA 66.4 (VPX with optical), and VITA 67.3 types (VPX with RF). The backplanes can be […]
