NI brings 14 GHz version of NI PXIe-5665
National Instruments (NI) has introduced a 14 GHz version of its NI PXIe-5665 high-performance RF vector signal analyzer (VSA). The VSA can deliver measurement speeds up to 20 times faster than box instruments and for less cost because of its PXI platform. It also offers data streaming for signal processing and a flexible multiple input, multiple output (MIMO) architecture for phase-coherent measurements.
"The new NI PXIe-5665 VSA gives ST-Ericsson the performance and accuracy we need for 3GPP RF IC design validation in our characterization labs. At the bottom line, the VSA reduces our system cost while increasing flexibility and decreasing physical bulk compared to our previous box solutions," said Sylvain Bertrand, RF Broadband Validation Manager, ST, Ericsson.
The VSA offers the 3.6 GHz version of the NI PXIe-5665 while extending the capabilities into the 14 GHz frequency range. The VSA consists of the new NI PXIe-5605 down converter, the NI PXIe-5653 local oscillator synthesizer and the NI PXIe-5622, a 150 MS/s intermediate frequency (IF) digitizer. This combination creates a solution for spectrum and wideband vector signal analysis over a frequency range of 20 Hz to 14 GHz with analysis bandwidths up to 50 MHz. It features the industry's third-order intercept point at +24 dBm with an absolute amplitude accuracy of +-0.10 dB as well as an impressive error vector magnitude of 0.33 per cent for a 256 QAM modulated signal. It also delivers an exceptionally low phase noise of 129 dBc/Hz at a 10 kHz offset at 800 MHz and an average noise level of -165 dBm/Hz.
