LitePoint Validated by Nordic Semiconductor for OTA Bluetooth® Low Energy Device Testing

Bluetooth® low energy chips from Nordic enable makers of advanced Internet of Things devices to rapidly bring innovative IoT products to market


LitePoint®, a leading provider of wireless test solutions, said today that Nordic Semiconductor has validated the LitePoint IQxel-M Bluetooth® Advanced wireless test system for over-the-air (OTA) testing of products that use Nordic’s market-leading Bluetooth® low energy Systems-on-Chip (SoCs).

This will enable IoT device makers utilizing Nordic’s nRF51 and nRF52 Series SoCs in their products to quickly perform critical OTA performance and functionality testing of their products to verify their designs and ramp to manufacturing. OTA testing is a requirement for Bluetooth® LE devices that do not usually allow for traditional wired test methods because they are often fully encapsulated.

Additionally, products that include the nRF51 and nRF52 Series SoCs do not need special test firmware when utilizing the IQxel-M, but instead utilize the system’s commercial firmware ensuring that the measurement results correlate with how the device is used in the end application.

white paper published on the Nordic website says, “The IQxel-M with LitePoint Bluetooth® Advanced measurement solution performs transmitter power, transmitter quality, and receiver sensitivity measurements, providing excellent coverage and confidence in the wireless performance of the device.”

Nordic’s market-leading nRF51 and nRF52 Series Bluetooth® low energy SoCs are based on ARM® M0, M4 and M4F processors and feature a range of devices with different features and Flash and RAM memory capacities for applications at all power consumption and cost levels. All Nordic’s Bluetooth® low energy solutions are fully compliant with versions of Bluetooth® technology from Bluetooth® 4.0 to the latest release.

“Nordic offers sophisticated wireless connectivity products which power advanced IoT applications. However, because the complexity of the product is hidden from the designer behind easy-to-use development tools, time to market is compressed,” said Jon Gunnar Sponås, Group Manager Technical Support with Nordic Semiconductor. “Nordic’s collaboration with LitePoint and its innovative OTA technology extends this design simplicity to testing because it means end products can be checked fully assembled, which better simulates real world conditions.”

“IoT systems and sensor manufacturers must balance the need for high RF quality, which can make or break a product, with cost sensitivity,” said Adam Smith, Director of Product Marketing at LitePoint. “We’ve developed the IQxel-M as a simple-to-deploy, over-the-air test solution that meets the needs of encapsulated IoT devices. We’re pleased to work with Nordic Semiconductor to provide a proven system to its customers.”

IQxel-M Technical Highlights

The IQxel-M is a comprehensive, one-box test solution for wireless connectivity testing and supports a wide variety of wireless standards including Wi-Fi, Bluetooth®, Zigbee, LoRa and Sigfox. IQxel-M also supports navigation technologies including GPS, GLONASS and Beidou. The system can perform parallel testing of multiple devices (multi-DUT) while at the same time enabling the concurrent test of multiple technologies (Multicom™).

IQxel-M was built from the ground up for manufacturing with its rugged and compact design, the 2U-high chassis fits in a standard 19-inch rack, making it easy for rack and stack implementations.
