Test and Measurement: R&S touts 5G mmWave angle-of-arrival testing

Rohde & Schwarz says it is the first test company with an over-the-air test system that is CTIA-authorized for multiple angles-of-arrival (AoA) testing, which is an important aspect of 5G device performance in millimeter-wave bands.

R&S said that testing multiple angles of arrival is “critical for verifying the performance of mobile devices in the mmWave space, as radio waves at these high frequencies … suffer from high path loss and therefore need to be focused in narrow beams that are challenging to find, track and hand over while moving.”

The test system that can achieve this type of testing includes the company’s R&S TS8980 conformance test system, plus its R&S CMX500 5G tester and its R&S ATS1800M mmWave (FR2) over-the-air testing chamber.

Keysight Technologies has a new MIPI compliance test solution for automotive serializer/deserializer receivers, developed in partnership with BitifEye Digital Test Solutions and Wilder Technologies with support from Valens Semiconductor. Keysight said that the solution supports implementations of MIPI A-PHY, a long-reach physical layer interface for automotive applications and others that depend on a surround-sensor environment such as cameras and in-vehicle infotainment displays.

Keysight also this week released the latest version of its flagship Pathwave Advanced Design System software for high-speed digital (HSD) design; the company highlighted improvements to its memory design features for the Double Data Rate 5 (DDR5) interface standard.

Rohde & Schwarz also said this week that its R&S ATS1500C antenna test system has a new temperature test option with the ability to test in a range from -40 °C to +85 °C, as well as a new feed antenna that supports parallel access to both polarizations.
