National Instruments announced NI-RFmx 2.2, the latest version of its advanced measurement software for PXI RF test systems. 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.
The latest release of NI-RFmx also features algorithm improvements for reduced measurement time. According to NI, 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 percent1 by installing the latest version of the software.
In addition to the algorithm improvements, NI-RFmx also adds enhanced 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 analyzer so engineers can configure PXI intermodulation distortion and noise figure test sets.
