Rohde & Schwarz launches low-power Bluetooth 5.2 to provide test solutions

“The Bluetooth test solution of the R&S CMW platform now supports the new Bluetooth Low Energy (BLE) 5.2 power control feature. This is also the only RF test instrument in the industry that supports the definition of BLE 5.0 scale (in air interface mode). As a new BLE test method, this test mode has been adopted by the Bluetooth SIG.

The Bluetooth test solution of the R&S CMW platform now supports the new Bluetooth Low Energy (BLE) 5.2 power control feature. This is also the only RF test instrument in the industry that supports the definition of BLE 5.0 scale (in air interface mode). As a new BLE test method, this test mode has been adopted by the Bluetooth SIG.

The Bluetooth SIG officially adopted the BLE 5.2 specification at the end of 2019. BLE 5.2 provides a new power control function. Rohde & Schwarz has completed the integration of related test items in the Bluetooth test software of the CMW platform. In addition, BLE 5.2 will provide extended audio functions similar to traditional Bluetooth. Once released, Rohde & Schwarz will also integrate related project tests.

New BLE test mode

On the other hand, Rohde & Schwarz is introducing a new BLE test mode based on BLE 5.0, which allows all test items defined by the specification to be completed under OTA, which is similar to the traditional Bluetooth test mode. The DTM connection requires an additional control line, which simplifies the test method. The test time is similar to that under DTM. This new OTA-based BLE test mode has been submitted to Bluetooth SIG.

The new test mode is developed based on the R&S CMW platform of the Rohde & Schwarz wireless communication tester, and is suitable for R&D and production testing in a test chamber. BLE receiver tests are generally based on the results of PER. In order to meet the needs of research and development, R&S CMW provides additional BER statistics functions.

Cover all Bluetooth RF test items

R&S CMW can complete the test of all Bluetooth test items, including traditional Bluetooth and Bluetooth Low Energy 5.2. It can also simulate devices for traditional Bluetooth connection and complete Bluetooth audio testing.

Support other wireless technologies

Rohde & Schwarz’s CMW500, CMW290 and CMW270 can also be applied to other wireless technologies. The hardware supports an analysis bandwidth of 160MHz and can support IEEE 802.11a/b/g/n/ac/ax standards. In addition, CMW also supports Zigbee technology applied to smart homes.
