New Software Enables NI PXI RF Test Systems to Test 4.5G and 5G RF Components

National InstrumentsNational Instruments, has announced the 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.

With the second-generation VST, engineers can simultaneously generate and measure up to 32 LTE carriers, each with 20 MHz of bandwidth, and use the software to specify a variety of carrier spacing schemes. The 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 percent by installing the latest version of the software. The measurement speed improvements in NI-RFmx are part of NI’s continued efforts to help customers lower their testing cost with faster measurements.

In addition to the algorithm improvements, NI-RFmx 2.2 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 easily configure high-performance PXI intermodulation distortion and noise figure test sets.

By adopting PXI and LabVIEW along with NI-RFmx measurement software, many NI customers in the semiconductor industry significantly cut test time for RF measurements, resulting in lower cost of test and faster time to market. The combination of excellent documentation, wealth of example code, and tight integration with PXI hardware like the second generation VST has allowed their customers to quickly and easily adopt NI-RFmx into their test systems.
