RF vector signal analyser

14 September 2011 Test & Measurement

National Instruments has introduced a 14 GHz version of its PXIe-5665 high-performance RF vector signal analyser (VSA), which delivers high dynamic range and accuracy in a cost-effective PXI form factor.

The new VSA features low phase noise and high dynamic range and, thanks to its PXI platform, can deliver measurement speeds up to 20 times faster than box instruments and for less cost. 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 well suited for demanding RF test applications including radar, satellite, radio and harmonic testing.

The instrument offers the same performance as the 3,6 GHz version of the PXIe-5665 while extending the capabilities into the 14 GHz frequency range. The VSA consists of the new PXIe-5605 down-converter, the PXIe-5653 local oscillator synthesiser and the PXIe-5622, a 150 MSps intermediate frequency (IF) digitiser. This combination creates a powerful 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.

The VSA features a third-order intercept point of +24 dBm with an absolute amplitude accuracy of ±0,10 dB as well as an error vector magnitude of 0,33% for a 256 QAM modulated signal. It also delivers low phase noise of -129 dBc/Hz at a 10 kHz offset at 800 MHz and an average noise level of -165 dBm/Hz.

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.
