An international team of astronomers has captured the first-ever polarized radio waves from a distant cosmic explosion.
The Square Kilometre Array (SKA) is set to become the largest radio telescope on Earth. Scientists of Bielefeld University and the Max Planck Institute for Radio Astronomy (MPIfR) with international partners have now examined the SKA-MPG telescope—a prototype for the part of the SKA that receives signals in the mid-frequency range.
D-TA Systems’ 4-channel standard MRSE-2000 system is designed to provide a phase coherent multichannel radar signal emulator platform that could simulate the backscatter returns from a distant flying target to a multiple channel radar system. This simulated RF output over the 4 channels would be used by the end-user to test their SUT for detecting and tracking long range radar targets. They will do this by utilizing waveform design diversity, beampattern, and scan pattern diversity on all the 4 channels.
As 5G NR networks are deployed, live network testing is needed to ensure network coverage and Quality of Experience (QoE). In addition, QoE testing in 5G NR will get more complicated due to changes in the network architecture. This means traditional testing will not reflect the true service quality as seen by an application. QoE field testing will need to be tested at the application layer to address the 5G NR QoE measurement challenge and translate the user experience into measurable KPIs.
Constellation diagrams are 2D graphical representations of digitally modulated signals. They are used for the display and analysis of digitally modulated waveforms and provide valuable insight into the performance of a digital communication system.
As the number of antennas grow in wireless systems, test complexity also increases. As a result, it is necessary to generate multiple RF channels for receiver testing and to analyze multiple RF channels for transmitter testing.
The U.S. and several NATO countries have been working on the seemingly impossible task of reducing size and weight of soldiers’ equipment while simultaneously increasing functionality and power. For engineers dealing with connectivity issues, this has brought about smaller and smaller connectors, cables and devices. Interconnected and portable devices have until now mainly been used by soldiers on covert operations. A wired tactical vest extends the concept of wearables beyond special forces by making the garments more modular, more accessible, and more affordable.

Within infrastructure, higher frequency ranges are increasing the size of the 5G network footprint. Can you keep up? This video introduces Qorvo’s solutions.
Our engineer takes you into the features, benefits and markets for the new AR-5010 amplifier. The AR-5010 is a class A amplifier designed with optimized performance to support linearly modulated, multi-carrier waveforms with high crest factors. The AR-5010 is a part of AR Modular RF’s AR-5000 Series which is the next generation of wide-band, Class A/AB linear amplifier designed for use with modern digital modulations.
Digital Phosphorus Technology, or DPX, is a Tektronix patented acquisition mode that performs the hardware DSP processing and rasterizing of the samples into pixel information in order to reveal a greater amount of signal detail. It gives a truly “live” view of the RF signals, with its color-grading feature allowing users to see different signals at the same frequency yet separated by either time or power levels. In this video, DPX is demonstrated and reveals signals that your old spectrum analyzer might be hiding from you. You can literally see signals hidden beneath other signals!
