Bluetooth Low Energy 5.2 boost from test family
The Bluetooth Special Interest Group (Bluetooth SIG) has adopted the first specifications for BLE 5.2 at the end of 2019. This initially concerns the new power control functions. The CMW platform Bluetooth testers from Rohde & Schwarz already support the new version 5.2 Bluetooth Low Energy power control test routines.
In addition, Bluetooth Low Energy 5.2 will provide extended audio functions similar to those of Bluetooth Classic. As soon as the specifications have been finalized, Rohde & Schwarz will expand the functional range of its Bluetooth testers accordingly.
Rohde & Schwarz is also 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 considerably, 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 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 CMW measures the bit error rate (BER) of a transmission in Bluetooth LE receivers in addition to the specified packet error rate (PER).
The 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.
The CMW500, CMW290 and 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.
