DTMF analysis on CMW500 and CMW290

How to configure a external trigger at CMW500, CMW290, CMW270 to synchronize with LTE signal time frames

CMW500 / CMW290: GPRS / EDGE packet data measurements failed because UE stay not in TBF (Temporary Block Flow) state.

How can the CQI (Chanel Quality Identifier) from UE and coresponding 3GPP specified mapping to Modulation and TBS be tested?

If a CMWrun test plan script has been fished the AC power of a CMW500 / CMW290 / CMW270 should be shut down automaticly.

During a CMWrun test my DUT fails on delivering isolated measurements using CMW270/290/500.

CMW500/290/270: No more WLAN signaling function after WLAN firmware update

It is required to run two simultaneous NB IoT Signaling tests in parallel. Is this possible for a CMW call box tester?

CMWrun Settings for external Interfer usage in Bluetooth LE Test Plans.

How can a WiFi connection instead be made to a WiFi network for remote access of the CMW?

How can the external attenuation values be configured and embedded in the CMWRun test sequences?

Is it possible to set up an IP peer to peer test using CMW500 between a corporate network and one EUT attached to an LTE cell?

The CMW500/2xx shows a resource conflict in this situation when using in parallel the RFxCOM port and the RFxOUT port of the same RF-frontend.

During the call setup with VoLTE/VoWiFi with EVS voice codec the bandwidth is negotiated. How can the bandwidth be setup and how will it be shown in the CMW user interface?

R&S TS 290 IoT carrier acceptance test system

20-Feb-2019

At MWC 2019, CommSolid (Goodix) will present a device solution that integrates NB-IoT and Bluetooth®. The manufacturer uses the R&S CMW290 IoT radio communication testers for RF and functional testing of both transmission methods. At Embedded World 2019 in Nuremberg, which takes place in parallel with MWC in Barcelona, Rohde & Schwarz will demonstrate the realistic measurements that make this device solution possible.

This application note describes Battery Life Measurements with the R&S®RT-ZVC02/04 Multi-Channel Probe. The measurements are described with the use of an oscilloscope.

Rohde & Schwarz has announced a collaboration with mobile test specialist COMPRION that gives telecommunication solution providers a method for testing remote SIM provisioning (RSP) of embedded UICCs (eSIMs) required for Industry 4.0 and connected car applications. The test solution is based on the COMPRION eUICC Profile Manager and the R&S CMW500 mobile communication tester or R&S CMW290 functional radio communication tester for cellular network simulation. For the certification process of the ERA-GLONASS based eCall system, RSP will be mandatory from 2020 onwards.

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. They can be optimized with the innovative test solutions Rohde & Schwarz designed specifically for this purpose. At Mobile World Congress, Rohde & Schwarz will present groundbreaking test scenarios with its R&S CMW platform of wireless testers.

Rohde & Schwarz and Goodix (CommSolid) are first to demonstrate exhaustive test functions for the newly introduced NB-IoT wake up signal (NWUS), the latest 3GPP Release 15 feature for NB-IoT devices to further reduce power consumption. For NB-IoT long-term monitoring applications, this wake up signal can be leveraged to enable either far longer battery life without upgrading the battery, or as a way to reduce battery size while retaining the device’s service life.
