Virtual drive tests during the development phase of CAT M1 and NB IoT modules help find and fix problems at an earlier stage. New test setups also enable seamless cellular coverage and reliable connectivity before the integration process continues and further field tests are performed. Network-specific integration tests and field tests include analysis of unique […]

IEEE 802.11ax compliant WLAN signaling test setup handles SISO, MIMO, OFDMA modes
An IEEE 802.11ax test solution for WLAN access points in multi-user operation (OFDMA) employs an R&S CMW270 Wireless Connectivity Tester to test the RF characteristics of receivers and transmitters and to determine the data throughput in the transmit and receive directions. With an R&S CMW270 Wireless Connectivity Tester and the WLAN 11ax signaling test option, […]
DesignCon video: Jitter analysis with an oscilloscope
All serial data streams have some jitter where the timing of bit edges differs from the ideal. With serval types of jitter composing a signal’s total jitter, you need to know which forms of jitter reduce bit-error-ratio. Oscilloscopes can decompose jitter and let you see which forms limit data transmissions. At DesignCon 2020, Rohde &…
Cloud/browser-based platform enables remote RF analysis
A cloud and browser-based application platform enables users to perform RF analysis remotely, without having to purchase a permanent software license. With R&S Cloud4Testing, users take advantage of different Rohde & Schwarz software solutions for testing – the only thing required is internet access and a valid subscription. R&S Cloud4Testing is an innovative software-as-a-service (SaaS) […]
Oscilloscopes add jitter analysis
The bits that travel over wireless networks also travel over wired networks, ultimately over cables and PCB traces as serial data streams such as Ethernet, PCIe, and others. All serial data transmissions must contend with jitter, the difference in timing from the ideal. Rohde & Schwarz has added jitter analysis to its RTO (600 MHz…
Scopes get jitter decomposition feature to aid debugging efforts
A new option for the R&S RTO and R&S RTP oscilloscopes helps development engineers gain more insight into the individual jitter components of their transmission interface. Now they can separate jitter into its random and deterministic components and view results flexibly for effective debugging. The Rohde & Schwarz decomposition algorithm uses a parametric signal model […]
Instrumentation checks out Wireless Emergency Alerts data
Rohde & Schwarz, in collaboration with LG Electronics Mobile Comm. U.S.A., Inc., have successfully verified Wireless Emergency Alerts (WEA) 3.0 features related to GEO-Fencing using an LG G8 ThinQ mobile smartphone. The new Enhanced Targeting Rules imposed by the Federal Communications Commission (FCC) in the United States, requires wireless providers to reach 100% of the […]
Validation for 5G comes to integrated LTE, WCDMA, GSM conformance test system family
The Global Certification Forum GCF and PTCRB certification organization have accepted first test-case validations in various FR1 and LTE band combinations using the new 5G RF conformance test system R&S “TS8980FTA-3A” from Rohde & Schwarz. The solution is the latest version of a successful family of RF conformance test systems and the only one in […]
R&S FPC1500 spectrum analyzer earns 2019 Leap Award
