Check and Measurement: Anritsu, ETS-Lindgren associate on NTN testing

Anritsu and fellow check gear firm ETS-Lindgren have collaborated on a brand new Non-Terrestrial Networks (NTN) testing resolution, which mixes Anritsu’s MT8821C Radio Communication Analyzer with ETS-Lindgren’s EMQuest antenna measurement software program and helps narrowband IoT NTN testing.

The MT8821C has a large dynamic vary, helps mobile applied sciences and maintains a steady wi-fi connection with a view to forestall disruptions throughout over-the-air testing, Anritsu mentioned, which means that it might probably cut back OTA check instances; the analyzer additionally helps check circumstances for Skylo’s NTN community.

James Younger, director of Wi-fi Options at ETS-Lindgren mentioned that the corporate was happy with how rapidly the mixing with Anritsu’s gear was achieved and added that the joint resolution signifies that over-the-air labs “can add NB-NTN expertise help with a simple improve to instrumentation and software program, plus seize the demand generated as cell community operators choose satellite tv for pc companions and speak in regards to the prospects of mobile companies from house.”

The 2 corporations mentioned in a launch that their collaboration is “not nearly expertise,” however that it’s a “important step towards the belief of a affluent community society, particularly in distant and underserved areas the place delivering terrestrial cell community protection is difficult.”

Individually, Anritsu additionally mentioned this week that it’s the first to get World Certification Discussion board certification for NTN NB-IoT radio frequency conformance checks. These checks had been validated on Anritsu’s New Radio RF Conformance Check System ME7873NR, and leveraged an Altair gadget from Sony Semiconductor Israel.

Levana Asraf Fouks, senior director of system validation and PM supervisor of system engineering at Sony Semiconductor Israel, mentioned that working with Anritsu on the early phases of improvement permits the corporate to put the groundwork for a sooner certification course of for NB-NTN modules and gadgets, including: “The validation of NTN NB-IoT RF conformance checks is a significant step ahead for the trade.”

In different check information:

–Rohde & Schwarz mentioned this week that it supported profitable characterization of a sub-Terahertz TX/RX multi-antenna chip (CHARM) in an over-the-air check chamber, working at as much as 140 GHz, in collaboration with Berkeley Wi-fi Analysis Middle (BWRC).

R&S additionally gave a preview of a new probe system for exact measurement of quick switching indicators, designed to work with its oscilloscope portfolio.

–Keysight Applied sciences teamed up with SmartViser to supply a joint resolution targeted on testing the Vitality Effectivity Index (EEI) of smartphones and tablets to satisfy the European Union’s power labeling mandate for these gadgets. Keysight mentioned that SmartViser’s check automation software program for cell gadgets can be utilized with any configuration of Keysight’s UXM 5G Wi-fi Check Platform.

In different information for Keysight this week, the corporate was ranked by Forbes as among the best corporations for variety, coming in at #8 out of 500 U.S.-based corporations.

–Spirent Communications’ AI visitors emulation platform took a prime prize at Interop Tokyo 2024; its 800G check equipment and Octobox Wi-Fi 7 check resolution additionally landed prime awards on the present within the check and measurement class.

-At subsequent week’s IMS 2024 present in Washington, D.C., mathematical computing software program firm MathWorks will current demos aimed at exhibiting engineers how one can design and analyze candidate waveforms for future 6G programs.
