Cellular NB-IoT Conformance Test

Keysight Technologies provides Conformance Test System for both RF NB-IoT and CAT-M validated test cases to 3GPP standards. They ranked first in the Global Certification Forum's (GCF) Conformance and Interoperability Agreement Group meeting (CAG#50) for most comprehensive Cellular-IoT test capabilities. The system can also be used to stress and test the performance of product outside the strict guidelines of the standards. Easily perform RF parametric testing or make block error ratio (BLER) and throughput measurements while also reviewing NAS to physical-layer operation. For more complicated tests, such as to sweep all modulations and coding schemes in an uplink, or to perform a margin search or even full system validation, the integrated Test Automation Platform simplifies the process.

IoT Device Battery Drain Analysis

Many IoT devices have a unique set of engineering demands. One of the biggest challenges is maximizing the life of small, on-board batteries. In order to achieve longer battery life, Engineers must make accurate battery drain measurements and understand the power consumption patterns. In many cases measuring the difference between on current and standby current requires resolution and measurement speed beyond that of even the hightest performance multimeters.  Keysight Technologies N6705x Power Analyser platform with a selection of high precision SMU's (source measure units) provides a solution to perform accurate battery drain analysis, accurately test IoT low-power consumption and characterize battery life of critical devices such as wireless medical devices and industrial control devices.

IoT Manufacturing Test

Conventional ways of IoT device functional testing include the golden radio method. Though it is low in cost, it does not provide sufficient test coverage to filter out manufacturing defects, nor the quantitative results that are important to detect performance drift or identify the root cause of failure. Parametric testers are another available method today, but they are an overkill at this point of the product’s life-cycle. These testers are also expensive, causing the cost of test to rise significantly with volume. This calls for an innovative and cost effective way of testing the functionality of RF devices after final assembly to ensure device quality and performance. Keysight Technologies X8711A is a unique integrated solution which measures important RF performance indicators of your IoT device while it is operating normally with production-release software. This ensures that your device is sufficiently tested for manufacturing defects including missing or wrong components, solder issues and more, without the need of complex or expensive test systems. The X8711A consists of the Keysight 34972A data acquisition/data logger switch unit with built-in 6 ½-digit digital multimeter, 34999A RF module and the TAP-based Bluetooth® Low Energy and WLAN b/g/n signaling measurement suites.
