The National Instruments 782366-01, known as the PXIe-5667 Vector Signal Analyzer, is a high-performance solution tailored for advanced spectrum monitoring and signal analysis tasks. This PXI Express-based system operates across a frequency range of 20 Hz to 3.6 GHz, featuring a maximum bandwidth of 25 MHz and the ability to expand up to 50 MHz with optional configurations. Its sub-octave bandwidth preselection enhances signal fidelity by effectively minimizing spurious signals and reducing interference potential. The analyzer boasts a low noise figure of less than 12 dB, ensuring exceptional sensitivity and accuracy for detecting weak signals.

Designed with a modular architecture, the PXIe-5667 comprises five essential PXI Express modules, including the PXIe-5622 IF Digitizer, PXIe-5694 IF Conditioning Module, PXIe-5603 or PXIe-5605 RF Signal Downconverter, PXIe-5653 RF Analog Signal Generator, and the PXIe-5693 RF Preselector Module. This configuration allows for effective signal acquisition and processing, with advanced tuning capabilities featuring a resolution of 533 nHz. The system's robustness is further enhanced by its low single-sideband phase noise, supporting phase-coherent measurements across multiple channels for synchronized analysis in complex environments.

The 782366-01 adheres to stringent safety and electromagnetic compatibility standards, such as IEC 61010-1 and EN 61326-1, and is designed to operate reliably under a wide range of environmental conditions, with a maximum operating temperature of 55 °C and humidity levels between 10% and 90%. The physical dimensions of the modules vary, with the combined weight of the system being 3289 g (115.9 oz). The product comes with a warranty of 2 to 3 years, reinforcing its reliability for demanding applications in industrial automation and control.
