Test & Measurement

What is said to be the industry’s first Protocol Conformance test in the Sub-6GHz Frequency Range 1 (FR1) has been submitted to the 3GPP RAN5 working group for approval by Anritsu. The test defined by 3GPP TS38.523 has been verified with Exynos modem 5100 5G New Radio (NR) modem developed by Samsung’s System LSI Business on Anritsu ME7834NR Protocol Conformance test system.  

At MWC 2019 in Barcelona (February 25-28) Commsolid (a Goodix company) will present an IoT reference design integrating its NB-IoT and Bluetooth SOCs. The manufacturer uses the R&S CMW290 IoT radio communication testers for RF and functional testing of both transmission methods.

The AWG70000B Series Arbitrary Waveform Generator has been launched by Tektronix with new features that enable it to fully support the testing of complex electronic warfare and wireless communications systems that require the ability to dynamically alter signal sequences during test scenarios.

MediaTek and Rohde & Schwarz are collaborating to perform over-the-air (OTA) tests of MediaTek’s 5G frontend modules and antenna arrays. The R&S TS8980R&D-M1 test system, which includes the new R&S ATS1800C CATR (compact antenna test range) chamber, will be used to fully characterise, verify and test the antenna performance of MediaTek’s 5G network solutions including its Helio M70 5G modem.

Successful validation of 5G NR cellular sub 6GHz signalling tests has been achieved by Rohde & Schwarz and Qualcomm Technologies. It brings the commercial roll-out of 5G NR one step closer. The end-to-end tests were done using the new R&S CMX500 radio communication tester, which will debut at Mobile World Congress 2019 in Barcelona (February 25-28).

Dual-channel microwave signal generators that support up to 44GHz signals and 2GHz radio frequency (RF) modulation bandwidth in a single instrument have been introduced by Keysight Technologies.  Keysight’s VXG microwave signal generators address demanding wideband millimeter wave (mmWave) applications for 5G and satellite communications by decreasing test set-up complexity and reducing path losses introduced in over-the-air (OTA) test environments.

As an infrastructure for smart cities and smart industries, the internet of things (IoT) is largely based on wireless components. Smooth component interaction, secure communications and long service life are essential success factors for this infrastructure.

Strengthening its position in WLAN signalling testing Rohde & Schwarz has unveiled the R&S CMW270 wireless connectivity tester which allows developers to test the RF characteristics of WLAN 2x2 MIMO stations in line with the IEEE 802.11ax standard.

Anritsu’s 5G NR RF Conformance Test System ME7873NR has won approval for 5G NR RF Conformance Tests and the 5G NR Mobile Device Test Platform ME7834NR has won GCF Validation for 5G NR Protocol Conformance Testsfrom the Global Certification Forum in January 2019.

An equivalent remote-controlled version of its SignalShark has been released by Narda Safety Test Solutions at an attractive price/performance ratio. This new Real-Time Remote Analyser detects and analyses, classifies and localises RF signals in the frequency range between 8kHz and 8GHz to the highest degree of precision and reliability.
