National Instruments introduced a 14GHz version of its NI PXIe-5665 RF vector signal analyzer (VSA). Because of its PXI platform, the VSA can deliver measurement speeds up to 20 times faster than box instruments. Additionally, it takes advantage of multicore computing architectures and parallel programming capabilities through NI LabVIEW system design software.

It also offers peer-to-peer data streaming for signal processing and a flexible multiple input, multiple output (MIMO) architecture for phase-coherent measurements. Such features make it suitable for demanding RF test applications including radio detection and ranging (RADAR), satellite, radio and harmonic testing.

The VSA offers the same performance as 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 NI PXIe-5605 downconverter, 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 a third-order intercept point at +24 dBm with an absolute amplitude accuracy of +/- 0.10 dB as well as an error vector magnitude of 0.33 percent for a 256 QAM modulated signal. It also delivers an low phase noise of -129 dBc/Hz at a 10 kHz offset at 800 MHz and an average noise level of -165 dBm/Hz.

Because the new 14 GHz NI PXIe-5665 joins an industry portfolio of more than 1,500 software-defined PXI modular instruments, engineers can mix and match the VSA with a variety of modules and control an entire automated test system with LabVIEW system design software.

Engineers can take advantage of the VSA's software-defined performance with RF software toolkits for LabVIEW, NI LabWindows/CVI and .NET to test the latest RADAR, satellite, radio and numerous RF and wireless communication standards including GSM/EDGE, WCDMA, LTE, WLAN and WiMAX. The 14 GHz NI PXIe-5665 VSA will be available for shipping this October.
