Basic tools such as DMMs and oscilloscopes may be the only test gear needed for small printed circuit board repairs, but it pays to know when automated systems would be a better choice. Alan Lowne | Saelig Co. Inc. PCBs are more complicated to repair today than even a few years ago. Manufacturing mistakes and […]
Web-based jitter measurement utility gives product designers critical timing test results in minutes
The new Jitter Measurement Utility is a web-based, fully automated tool that enables designers to quickly and easily evaluate the jitter and phase noise performance of their custom clock configurations without using their own test equipment. “The need for higher timing performance is being driven by the introduction of new technologies such as 5G, mmWave, […]
Basics of cavity resonators
Experimenters beware! If you think it might be instructive to dismantle a microwave oven and power up the magnetron to make a space gun, don’t do it. A microwave gun (called a magnetron) in a state other than as manufactured has numerous potential hazards. (Nevertheless, you can find a lot of YouTube videos describing exactly […]
Test gear rapidly detects, locates, report optical fiber breaks up to 100 m away
A new testing solution detects problems within optical fibers. AddOn’s EON-NSV-OTDR devices rapidly locate and report any faults in an optical fiber link of a communication network – saving service providers time and money by allowing them to quickly address the root cause of any issues. The detection of problems within optical fibers is critical […]
New device accurately measures gap, vibration and positioning
A third-generation digital capacitance displacement gauge features low noise and industry-leading resolution. The Accumeasure D Series (“Gen 3”) is designed with OEM customers in mind. With both analog and digital outputs, the Gen 3 can be seamlessly integrated into products to measure, monitor, and provide instant closed loop feedback for critical process parameters including gap, […]
The difference between scanning electron microscopes and tunneling scanning electron microscopes
Compared to an optical microscope, the electron microscope achieves far greater resolution and magnification by taking advantage of the wave aspect of electrons. An electron’s wavelength is typically 1/100,000 that of visible light. Resolutions of 50 pm and 10 million-X magnification have been achieved, far better than the 200-mm resolution and 2,000X magnification of a […]
Web-based approach automates waveform data acquisition, screenshot captures, analytics, data visualization for scopes
Instruments from RIGOL Technologies are now integrated into GradientOne’s test automation cloud platform to simplify the day-to-day tasks of test engineers ranging from hobbyists to enterprise users. GradientOne frees test engineers from the high cost of developing and maintaining test data analysis solutions by providing a cloud-based platform for remote control, data acquisition, single system […]
The difference between CCD and CMOS image sensing
Charge-coupled devices (CCDs) and complementary metal-oxide-semiconductor (CMOS) technology have been in fierce yet friendly competition. Fierce because valuable market share is contested, friendly because the rival digital camera technologies have much in common. It is ironic that the more-costly CCD sensor is used in the most advanced astrophotography instruments and also in low-end point-and-shoot cameras, […]
5G technology said to usher in new generation of robots
The 5G technology that is on the horizon is being described as a once-in-a-generation technological advent. The massive capacity, ultra-low latency, and high reliability of 5G communications will enable entire new ecosystems of connected technologies to flourish. In the field of robotics, this will mean everything from highly precise industrial robots that can be controlled […]
Gallery: Interesting instruments on display at PCIM Europe
PCIM Europe is often proclaimed to be the world’s leading exhibition and conference for power electronics, intelligent motion, renewable energy, and energy management. Recently finishing up in Nuremberg, the exhibition floor of PCIM featured over 500 booths. Here are some of the more notable test & measurement we saw in touring the event. NEXT PAGE: […]
