4.5G test system cuts RF measurement time by 33%

Article By : NI

The NI-RFmx 2.2 measurement software for 4.5G and 5G RF components can measure up to 32 LTE carriers, each with 20MHz of bandwidth.

NI has launched its measurement software for PXI RF test systems, the NI-RFmx 2.2. When used with the second-generation PXI Vector Signal Transceiver (VST), engineers can test 4.5G and 5G RF components such as transceivers and amplifiers using a wide range of carrier aggregation schemes (even as the 5G standard is still being defined), generate and measure up to 32 LTE carriers, each with 20MHz of bandwidth, and use the software to specify a variety of carrier spacing schemes.

The latest release of NI-RFmx also features algorithm improvements for reduced measurement time. Engineers performing modulation quality and spectral measurements for wireless technologies such as UMTS/HSPA+ and LTE/LTE-Advanced Pro can experience EVM measurement time reductions of up to 33% by installing the latest version of the software.

In addition to the algorithm improvements, NI-RFmx also adds support for measurements such as intermodulation distortion, third order intercept and both Y-factor and cold source noise figure measurements. These measurements integrate easily with the PXIe-5668R RF signal analyser so engineers can easily configure high-performance PXI intermodulation distortion and noise figure test sets.
