Product Brief
PXI RF test performance extended to 14 GHz
Colin Holland8/2/2011 8:37 AM EDT
A 14 GHz version of the National Instruments PXIe-5665 RF vector signal analyzer (VSA) has been developed in a PXI form factor. It takes advantage of multicore computing architectures and parallel programming capabilities through NI LabVIEW system design software.
It also provides 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 ideal for demanding RF test applications including radio detection and ranging (RADAR), satellite, radio and harmonic testing.
The VSA offers has similar 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 synthesiser 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 error vector magnitude of 0.33 percent for a 256 QAM modulated signal. It also delivers phase noise of -129 dBc/Hz at a 10 kHz offset at 800 MHz and an average noise level of -165 dBm/Hz.
The14 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. It will be available for shipping this October.
