Overcome Open RAN test and certification challenges

1 week ago | 5gtechnologyworld.com | Ian Y Wong |Martin Rowe

LaaS Testing can streamline deployment and enhance efficiency for reliable Open RANThe race to build 5G networks has gone on for several years, extending coverage and providing access to advanced services. Initiatives such as Open RAN make for high-performing, robust, and agile mobile infrastructures that are in the interest of consumers and businesses, as well as the wider economy.
Signal Hound claims first 40 GHz USB VNA

1 week ago | eeworldonline.com | Martin Rowe

RF components such as connectors, cables, antennas, and PCB traces need characterizing so you know how they will perform. That’s where a vector network analyzer (VNA) can help. Signal Hound, well known for its USB spectrum analyzers, has introduced the VNA400, a 40 GHz VNA that connects to and gets power from its single USB-C port. The two-port VNA400 lets you send a signal to your device under test (DUT) and measure its response, producing S-parameters.
OFC 2025: Interoperability demos

2 weeks ago | 5gtechnologyworld.com | Martin Rowe

The Ethernet Alliance and Optical Networking Forum featured interoperability demonstrations at data rates up to 800 Gbps. San Francisco — With so many companies and products comprising the optical networking ecosystem, interoperability is paramount. All those semiconductors, optical modules, switches, routers, servers, test equipment, and the software that makes them function must first provide their compliance to standards and then prove themselves in real-world situations.
Modular system combines DMM with DAQ

3 weeks ago | eeworldonline.com | Martin Rowe

The DAQ3120 from B+K Precision lets you install up to three measurement modules to create a custom system for your bench. Most engineers have a digital multimeter (DMM) for basic measurements such as voltage, current, and resistance. Sometimes, however, you need the flexibility to add channels and log measurements without or without a computer. That’s where the DAQ3120 from B+K Precision comes in. The DAQ3120 measurement engine is a 6½ digit DMM.
APEC 2025 test equipment: power sources and loads

4 weeks ago | eeworldonline.com | Martin Rowe

Powering electronic devices requires the testing of power supply and charging circuits, battery management systems (BMSs), and battery cells. Many of these circuits require voltage, current, and power measurements, plus numerous others. Oscilloscopes and probes let you see the waveforms in power-delivery circuits, but the circuits themselves may need simulated batteries and simulated loads. That’s because you often have to design power circuits before the final product is available.
APEC 2025 test equipment: oscilloscopes and probes

4 weeks ago | eeworldonline.com | Martin Rowe

Oscilloscopes and probes play a vital role for engineers designing and testing power electronics. Delivering electrical power to analog and digital circuits and systems is more than just DC measurements. That’s because nearly all power-converter circuits use switching techniques to maximize efficiency. Silicon carbide (SiC and gallium nitride (GaN) transistors, with their higher voltage and switching frequencies, raise switching frequencies over silicon transistors.
Why engineers need IC ESD and TLP data

1 month ago | eeworldonline.com | Martin Rowe

Design engineers need ESD and TLP characterization data to make informed decisions to design robust circuits and systems. Engineers often review semiconductor data among several manufacturers when designing a circuit or system. While two or more ICs may perform satisfactorily under normal operating conditions, they may not perform the same under extreme conditions, such as when hit with an electrostatic discharge (ESD) event.
DSL Router Innovation with Recycled Phone Parts

1 month ago | eeworldonline.com | Martin Rowe

A consortium of companies found a clever way to recycle phone parts, showing how reusing electronics can improve sustainability. Electronic waste is a huge environmental problem of which disposed cell phones are a major contributor. Think about it, all that metal, plastic, and working semiconductors go into landfills. Some materials, such as gold from PCB fingers, can be reclaimed and used in other ways, but what if the working semiconductors could get a second life?

500 V SMT transformers shrink in size

1 month ago | eeworldonline.com | Martin Rowe

TDK has announced the EPCOS EP9 series of surface-mount transformers (ordering code B82804E). At 13 × 11 × 11 mm, these parts are smaller than the company’s existing E10EM series of SMT transformers designed for IGBT and FET gate driver circuits. Engineered for high performance in demanding e-mobility and industrial applications with 500 V system voltage, these components offer high insulation, low coupling capacitance, and high thermal resilience.
