Five challenges for developing next-generation ADAS and autonomous vehicles

4 days ago | eeworldonline.com | Martin Rowe

ADAS and autonomous vehicles need new datacom architectures and new attitudes. The state of California requires autonomous vehicle manufacturers to annually document and report every manual intervention by test drivers, including the cause and the vehicle’s mileage. In less than five years, these reports have demonstrated significant improvements in miles per intervention for virtually every car company.
6G needs less, 6G needs more

1 week ago | 5gtechnologyworld.com | Martin Rowe

From radios to core networks, a consensus is forming that 6G needs to offer more focused technology than 5G, or is it more technology? Energy, spectrum, and AI top the list of what 6G needs. EE World spoke with four engineers who attended the March 3GPP meeting in Korea. Here’s what they had to say. If you ask people, “Has 5G been successful?” you get different answers depending on who you ask.
Connector provides high power from batteries to loads

The Industrial Battery Connector line from Anderson Power handles up to 450 A, senses its temperature, and provides pins for data communications. The electrification of just about everything means power from batteries must reach loads with ever-increasing power.
Pulse Generator: Uncovering Its Metal Design

1 week ago | eeworldonline.com | Martin Rowe

This 50 MHz pulse generator was built as solid as a rock. It’s almost all metal. We take the unit completely apart and look at it from a system and board level. On a visit to the MIT swapfest in 2024, I came across an HP 8112A 50 MHz pulse generator. For $20, I brought it home to take apart. This instrument, assembled in the Federal Republic of Germany circa 1987 before the fall of the Berlin Wall, is a classic example of a solidly built piece of test equipment. Here’s what’s inside.

Spirent adds Wi-Fi 6/7 automated tests to Octobox

1 month ago | eeworldonline.com | Martin Rowe

The STA Automation Package automates testing that provides repeatability while minimizing manual intervention. The latest flavors of Wi-Fi bring a significant jump to performance over previous iterations. Testing, however, proves difficult because every Wi-Fi installation is different. Spirent Communications has introduced the Octobox STA Automation Package, which automates Wi-Fi 6/6E and 7 over-the-air (OTA) testing. Yes, it’s compatible with previous Wi-Fi versions.

OFC 2025: The Future of Optical Connections

1 month ago | eeworldonline.com | Martin Rowe

San Francisco — At last year’s OFC 2024, the next speed of optical connections (1.6T) was all talk with one exception. In a back room, Keysight demonstrated a 1.6T optical link between an arbitrary waveform generator and a bit-error-rate tester. The demonstration was a transmission of raw, unstructured bits. One thing was clear: AI was going to drive engineers to develop 1.6T optics that carry structured bits such as Ethernet.
Phone chargers produce EMI: We compared four

1 month ago | eeworldonline.com | Martin Rowe

The switching power supplies that regulate output voltage produce radiated emissions. Our tests compare waveforms that give clues as to how the chargers operate. While evaluating the Uni-T UPO1202 oscilloscope, I used the Uni-T UTG962E Function/Arbitrary Waveform Generator and noticed some noise in my measurements. Some came from the LED task lighting above my bench, so I turned the LEDs off.
