Narrow-band-IoT test software cuts development time

November 27, 2017 // By Graham Prophet
Anritsu has made available NB-IoT software options for the MT8870A universal test set to provide high-speed RF measurements for NB-IoT devices and reduce test software development man-hours by almost 90 percent.

The NB-IoT software options comprise the NB-IoT Uplink Tx Measurement MX887067A software and NB-IoT Downlink Waveforms MV887067A package – supporting 3GPP RF measurement tests for NB-IoT devices, running on the MT8870A universal wireless test set.

Installing the NB-IoT options in the MT8870A enables evaluation of communications equipment with built-in NB-IoT functions as well as tests of the RF TRx characteristics of modules. These same options are bundled with a PC application supporting signal analysis to assist users with development work and design testing. A fully automatic measurement application is provided for controlling measuring instruments and chipsets at prototyping and mass-production testing. These application software packages can be used to simplify test program creation and automate measurement, cutting customers’ test software development man-hours by about 90 percent.

Narrowband-IoT (NB-IoT) offers several advantages, including improved power consumption, extended in-building coverage, lower cost and improved security and privacy features. But to be able to meet to growing demand for NB-IoT modules, chipset vendors are looking at cutting the cost of manufacturing by improving measurement efficiency. Anritsu has worked closely with chipset vendors to develop a turnkey system supporting fully automatic measurement. These latest options make full use of optimization technology developed as a manufacturing solution for 2G/3G/4G terminals and have been developed as a multi-device test solution for cutting measurement costs per device as far as possible.

The MT8870A is a universal wireless test set designed for the mass-production of wireless communication devices, including 2G/3G/LTE/LTE-A, W-LAN, Bluetooth, GPS and FM technologies. Up to four high-performance test units can be installed in one main chassis, with each unit performing completely independent parallel measurements to evaluate up to four wireless communications devices simultaneously.
