Test equipment plays a major role in product development and production, which was apparent at IMS 2023. In the photos and videos below, you’ll get a taste of test developments at RF, mmWave, and sub-THz frequencies. This year, D-band (110 GHz to 170 GHz) seized a larger portion of the exhibit hall than in past […]
Test Equipment
SoC generates RF test signals and analyzes results
The Apollo MxFE software-defined signal processing SoC from Analog Devices digitizes and generates analog signals with DSP in between. Applications cover aerospace & defense, instrumentation, and wireless communications. Digitizing high-speed signals, processing them, and creating responses typically requires separate ADCs, DACs, and DSPs or FPGAs. The Apollo MxFE system-on-chip (SoC) combines signal capture, creation, and […]
EE World’s 2023 T&M Handbook is now available
For 2023, the digital version features 11 technical articles that cover test from signal integrity on the bench to automated test on the production floor.
Co-packaged optics: promises and complexities
Integrating optics into the same package as switching ASICs improves signal integrity and increases data rates, but challenges remain. Near-packaged optics could emerge as an interim solution to the problem. The constant need for more throughput in data centers pushes engineers to develop ever-faster optical and electrical links. In addition to designing for more speed, […]
5G mmWave test builds on RF best practices
The high level of integration in today’s mmWave phone means traditional test methods no longer apply.
What are the critical measurements in satellite uplinks and downlinks?
Noise measurement, LO substitution, receiver stress testing, power measurement, CCDF and PAPR characterization, and antenna-pattern measurement play critical roles in link budget, bit-error rate, and SNR requirements.
Test methods for mmWave AiP designs bring tradeoffs
Engineers have several mmWave over-the-air test methods available for evaluating phased-array antennas used in antenna-in-package designs. Each has pros and cons.
IoT devices in private 5G networks bring new verification tests
With private networks connecting to many IoT devices, testing the device’s user interface requires updating test processes. Many IoT use cases rely on private 5G networks because they offer greater network control, better security, more reliable performance, and dedicated coverage and capacity as opposed to using a public network. With these advantages, private networks play…
Water-cooled probe injects disturbances onto power rails
The P2124 from Picotest let’s you inject modulation signals onto your board’s power rails for noise immunity testing.
I’ve got the measurement blues again
Back from a three-year hiatus, I’m covering test and measurement again. This time, it’s for EE World.
