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

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

IoT devices have tight requirements for power consumption in order to achieve expected battery life times of multiple years without a connection to a power supply. In order to verify the power consumption and expected battery life time, voltage and current have to be measured accurately for different operating states of the device under test.This application note explains battery life tests using RT-ZVC in combination with CMWrun and CMW500, including example applications.The solution by Rohde & Schwarz enables precise voltage, current and consequently, power measurements.The RT-ZVC Multi-Channel Power Probe can be driven as part of a test plan combining signaling and power measurements for a detailed view of the power consumption in different signaling states as well as an estimation of overall lifetime given a certain battery capacity.

Rohde & Schwarz – recognized as a reliable partner for WLAN testing solutions: As a leading supplier of T&M solutions for the wireless communications market, Rohde & Schwarz offers the R&S®CMW wideband radio communication tester, a universal, flexible platform for all major cellular and non‑cellular standards. The R&S®CMW measures the RF characteristics of transmitters and receivers on the air interface of wireless devices. It evaluates the applications and performance, and analyzes the protocol stack.

This document describes the adaptive frequency hopping mechanism for improved signaling performance in Bluetooth Basic Rate and Enhanced Data Rate devices.The R&S CMW provides this feature for remote operation in TX, Loopback and Connection test mode. Thereby the R&S CMW acts as a master, while the Equipment under Test (EUT) represents the slave(s) of the piconet.

More and more everyday items such as household appliances, vehicles, lights, etc. are now connected to the Internet, forming what is known as the "Internet of Things". Even clothing with sewn-in sensors to measure vital functions can now connect to the Internet and transmit data to cloud services. These different things use a variety of wireless technology standards to establish a connection. Due to its popularity, one of the most important standards is Bluetooth (or Bluetooth Low Energy). Before a new product with Bluetooth functionality can be launched, the qualification process defined by the Bluetooth SIG must be successfully completed. To save time and money, performance tests need to be performed in the development stage. This application note describes how to use the R&S CMW platform to perform the measurements defined in Bluetooth test specification version 5. As an alternative solution, we also cover how to perform almost all of the measurements with a spectrum analyzer and signal generator.The Bluetooth® word mark and logos are registered trademarks owned by Bluetooth SIG, Inc. and any use of such marks by Rohde & Schwarz is under license.

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

For establishing a WLAN connection between R&S®CMW and device under test (DUT), the WLAN properties at the R&S®CMW have to be adapted to the test conditions. These can vary in several aspects, particularly due to the different WLAN standards and characteristics of the DUT. This document describes the critical parameters and provides step-by-step procedures for the configuration.

This document describes the direct test mode mechanisms for testing Bluetooth Low Energy devices and explains how the direct test mode connection is established. The R&S CMW uses a USB port for the direct test mode connection while the Equipment under Test (EUT) may provide a USB port, a serial port or even a 2-wire UART interface for this purpose. Installing or assigning the right driver for the EUT is the main configuration task on the R&S CMW. For EUTs with USB port, the R&S CMW provides a Bluetooth Low Energy USB driver which has to be assigned to the connected EUT.
