pulse Testing prepares for Bluetooth 5 Rohde & Schwarz has expanded the functional range of its CMW wideband radio communication testers to cover the Bluetooth 5 specification. The R&S CMW software encompasses all RF tests needed for development and production, including the new test cases for Bluetooth SIG precertification. The Bluetooth Special Interest Group (SIG) has specified new low-energy (LE) features in Bluetooth 5 that are tailored primarily to Internet of Things (IoT) applications. A key criterion for these applications is the lowest possible power consumption. An option is now available that makes it possible to quadruple the range of Bluetooth connections by transmitting data multiple times. The new specification permits transmission speeds of 1 Mbit/sec and now also 2 Mbit/sec. This optional stable modulation index has been integrated into the Rohde & Schwarz test software. The CMWKM721 software option is used to measure power, modulation and adjacent channel power (ACP) on the transmitter. With the software option, receiver measurements can be performed to determine the packet error rate and receiver sensitivity. R&S says that the CMW testers are currently the only products on the market that deliver RF tests on Bluetooth and cellular radio signals such as LTE-A, WCDMA, GSM and CDMA2000, as well as non-cellular radio signals such as WLAN, ZigBee and GNSS, using a single instrument.

The company previously announced technology to extend the capacity of copper to data rates as high as 100G – that being on direct point-to-point copper links within large data centres. Now it is turning its attention to allowing inbuilding wiring in commercial environments to support higher data rates without upgrading the cable infrastructure – increasing speeds from established gigabit Ethernet. A big driver, the company says, its the advent of the IEEE 802.11ac wireless standard; routers supporting many lined clients need a “wide pipe” to feed them.
