National Instruments Aust & NZ  introduces a 14 GHz version of its NI PXIe-5665 high-performance RF vector signal analyzers (VSA) that delivers excellent dynamic range and accuracy in a cost-effective PXI form factor.  

The new vector signal analyzer delivers industry-leading performance, surpassing box instrumentation and extending the capabilities of the 3.6 GHz version of the NI PXIe-5665 into the 14 GHz frequency range.  

The RF vector signal analyzers incorporate several features that make them ideal for demanding RF test applications including radio detection and ranging (RADAR), satellite, radio and harmonic testing.  

The new VSA features superior phase noise and dynamic range, regardless of form factor, including traditional rack-and-stack instruments. Its PXI platform allows the VSA to deliver measurement speeds up to 20 times faster than box instruments and for less cost.  

It additionally, 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.  

According to Sylvain Bertrand, RF broadband validation manager at ST-Ericsson, the new NI PXIe-5665 VSA gives ST-Ericsson the performance and accuracy required for 3GPP RF IC design validation in their characterization labs. Consequently, the VSA reduces their system cost while increasing flexibility and decreasing physical bulk compared to previous box solutions.      

Key features of the new RF vector signal analyzers: 

  • Consists of the new NI PXIe-5605 downconverter, the NI PXIe-5653 local oscillator synthesizer and NI PXIe-5622, a 150 MS/s intermediate frequency digitizer
  • Combination creates an ideal 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
  • Incorporates third-order intercept point at +24 dBm with an absolute amplitude accuracy of ±0.10 dB
  • Impressive error vector magnitude of 0.33% for a 256 QAM modulated signal
  • 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

With the new 14 GHz NI PXIe-5665 joining 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 also 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.
