Rohde & Schwarz showcased the world’s first Bluetooth low energy signaling test solution at the 2018 Bluetooth World Conference

Many manufacturers of Bluetooth low energy components find it very challenging to test modules and sensors in accordance with standards. These devices usually do not have ports or interfaces to connect control lines required for testing in accordance with the Direct Test Mode (DTM) specified by the Bluetooth Low Energy standard. Rohde & Schwarz’s R&S CMW test platform can now perform spatial coupling (OTA) testing and conduction testing of these devices.

Munich, September 18, 2018-Rohde & Schwarz demonstrated the RF signaling test under actual conditions at booth 333 of the 2018 Bluetooth World Congress held in Santa Clara, California from September 18 to 19 Bluetooth low energy (BLE) signaling test program.

Bluetooth low energy has emerged as a major transmission technology for the Internet of Things (IoT). When the BLE test specification was drafted in 2010, the Bluetooth Technology Alliance proposed a direct test mode (DTM, non-signaling), but did not specify an OTA signalling test mode. DTM requires a dedicated control line to connect the DUT. Nevertheless, the control line cannot be tested in a real environment because the measured radio frequency characteristics are deviated from the real test value. It is complicated but feasible to test the direct test mode of board-level BLE components in the development stage. In contrast, it is difficult or even impossible to perform DTM radio frequency testing for production lines and OTA applications (for example, in shielded boxes). Many BLE devices do not provide ports or interfaces to connect control lines, but they need to be tested in real scenarios. Rohde & Schwarz has now launched the first solution for BLE radio frequency signaling testing in real scenarios.

Fast OTA RF test in real scenarios

Rohde & Schwarz’s BLE signaling test solution makes it possible to determine the radio frequency performance of Bluetooth low energy devices through a Bluetooth OTA connection or a cable connection to the antenna. In this way, users can, for example, measure the level, modulation, and receiver performance of a single or all data channels in a typical Bluetooth characteristic of frequency hopping transmission. Rohde & Schwarz also provides options for broadcast testing, because the R&S CMW test platform can test the radio frequency parameters of the broadcast channel. The BLE signaling function enhances the functions of BLE direct test mode and BLE broadcast mode. With these functions, it is now possible to solve complex measurement tasks in R&D, production and OTA application scenarios. Using R&S CMW, users can now choose from three BLE radio frequency test modes to match their own application. This also makes the R&S CMW platform a safe investment in future Bluetooth R&D.

Full-featured Bluetooth RF tester

The R&S CMW test platform covers the entire range of Bluetooth radio frequency testing, including classic Bluetooth, Bluetooth low energy and the latest standard, Bluetooth 5.03. Along with signaling test and direct test mode, R&S CMW supports various Bluetooth basic rate/enhanced rate (BR/EDR) audio tests. The R&S CMW test platform is particularly suitable for R&D, pre-certification testing, audio certification testing and Bluetooth OTA testing.

R&S CMW270: Single meter for Bluetooth, WLAN and Zigbee testing

At this year’s Bluetooth World Congress, Rohde & Schwarz will demonstrate its R&S CMW270 wireless connectivity tester. It relies on a parametric test concept, allowing users to create and execute customized test sequences. The bandwidth of the tester has been expanded to 160 MHz. This also enables it to support WLAN radio frequency signaling tests covering IEEE 802.11a/b/g/n/ac and IEEE 802.11ax standards. Radio frequency tests that comply with the IEEE 802.15.4 standard of Zigbee and Thread components are also supported.

Rohde & Schwarz has demonstrated the R&S CMW270 that supports Bluetooth low energy signaling test function at Booth 333 of the 2018 Bluetooth World Congress in Santa Clara, California on September 18 and 19. Detailed information about Bluetooth Low Energy (LE) and Classic Bluetooth can be found
