Wireless communication tester from the R&S CMW series from Rohde & Schwarz.

Rohde & Schwarz CMW wireless communication testers are ready for Bluetooth Low Energy 5.2

  • Rohde & Schwarz has integrated the specified tests of Bluetooth Low Energy Version 5.2 (BLE 5.2) into the Bluetooth test software of its R&S CMW series testers.
  • The wireless communication test instruments of the R&S CMW family can perform all Bluetooth compliance radio frequency tests: from Bluetooth Classic to Bluetooth LE and Bluetooth 5.2.

At the end of 2019, the Bluetooth Special Interest Group (Bluetooth SIG) adopted the first specifications of the Bluetooth Low Energy version (BLE 5.2), which include new power control functions. BLE 5.2 will also have extended audio functions similar to those of Bluetooth Classic. As soon as the specifications are finalized, Rohde & Schwarz will integrate the test functions for its Bluetooth testers.

The new Bluetooth LE test mode
In addition, Rohde & Schwarz is introducing the new Bluetooth LE test mode for Bluetooth LE 5.0. Similar to Bluetooth Classic, it allows manufacturers to perform all RF and pre-conformance tests on their Bluetooth LE components via the air interface (OTA). This simplifies testing, as no additional control cable is required as would be necessary for direct test mode (DTM). Testing times are just as short as when using DTM. The OTA test procedures have already been submitted to the Bluetooth SIG for specification of a new Bluetooth LE test mode.

The new test mode is based on the R&S CMW platform of wireless communications testers from Rohde & Schwarz and is suitable for measurements during development, production and in test chambers. As an additional highlight for developers, the R&S CMW measures the bit error rate (BER) of a transmission in Bluetooth LE receivers in addition to the specified packet error rate (PER).

Covers all Bluetooth RF conformance tests
The R&S CMW can perform all Bluetooth RF conformance tests – from Bluetooth Classic to Bluetooth LE and Bluetooth 5.2. It can also perform a multitude of audio tests on Bluetooth basic rate/enhanced data rate (BR/EDR) connections.

Testing of other wireless technologies
The R&S CMW500, R&S CMW290 and R&S CMW270 wireless testers are also suitable for testing other wireless technologies. With 160 MHz measurement bandwidth, they can test all RF parameters specified in all IEEE 802.11a/b/g/n/ac standards, including 802.11ax. The testers can also perform RF tests on Zigbee components for smart home applications.
