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, […]

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.
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.
What is a Smith chart and why do I need one? (Part 1)
A Smith chart provides insight into RF/microwave designs. Even if you work primarily with low-speed analog and mixed-signal designs, you could benefit from familiarity with the Smith chart as wireless products proliferate and as high-speed-serial data signals exhibit microwave-like effects. When a signal’s wavelength (λ) approaches the lengths of the conductors carrying it, you can […]
Test gear checks out Wi-Fi 7 chipsets
An automated test solution checks out Broadcom Wi-Fi 7 chipsets, the industry’s first Wi-Fi 7 chipsets optimized for mobile handsets that also support simultaneous dual-band 2×2 IEEE 802.11be-compliant operation. Rohde & Schwarz collaborated with Broadcom to successfully verify the R&S CMP180 next generation wireless device test platform for R&D and production. The IEEE 802.11be amendment […]
Programmable attenuators cover dc to 40 GHz
A new series of programmable attenuators covers broadband RF, microwave and mmWave frequencies ranging from dc to 40 GHz. They provide greater flexibility and programmability by allowing different values of RF signal attenuation on demand. These new high-performance attenuators are available in TTL, USB or relay-controlled options. They also feature switching speeds of 0.35 μsec […]
Multi-channel coherent microwave RF source hits 20 GHz
A new RF Microwave Generator, the DSG5000 Series, can generate up to 20-GHz carriers with high signal fidelity. These new generators are available with two, four, six, or eight independent RF channels packaged in a single 2U full width mainframe. The DSG5000 Series features impressive long term phase stability between channels of ±1 degree and […]
GNSS simulator features compact form factor
The GSG-7, the latest Global Navigation Satellite System (GNSS) signal testing solution offered through the Orolia family of Skydel-based simulators, features a small form factor, an internal RF combiner, high-end performance with a 1000 Hz simulation iteration rate, real-time synchronization, Hardware-in-the-Loop (HIL) integration, powerful automation, and multi-constellation and multi-frequency simulations. “The GSG-7 is redefining the […]
Antenna test system enables temperature-controlled measurements, polarization access
The R&S ATS1500C antenna test system from Rohde & Schwarz offers a new temperature test option and a new feed antenna. These additional features enable temperature-controlled measurements in a wide temperature range as well as parallel access to both polarizations, increasing test efficiency and flexibility. The movable R&S ATS1500C is a compact antenna test range […]
