National Instruments 781259-01 RF Vector Signal Generator
Designed for modular PXI Express systems, part number 781259-01 from National Instruments is an identifying part number for the PXIe-5663E RF Vector Signal Generator. The 781259-01 is not a singular module, but the interconnected models of the PXIe-5601, the PXIe-5622, and the PXIe-5652.
Part number 781259-01 is a 6.6 GHz RF vector signal analyzer (VSA) with digital down conversion. It is an integrated set of modules intended to provide high-performance signal analysis capabilities rather than a single physical device. It consists of a RF analog signal generator, IF digitizer, and RF signal downconverter. The system provides a nominal RF input level of 0 dBm and a maximum input level of +20 dBm, covering a broad frequency range of 10 MHz to 6.6 GHz. For versatile signal routing, the PXIe-5663E has several ports, including RF IN, IF OUT, LO IN, and LO OUT. It performs well in conditions with relative humidity ranging from 10% to 90% and temperatures between 0°C and 55°C.
This analyzer has an amazing tuning resolution of 533 nHz and runs across a broad frequency range of 10 MHz to 6.6 GHz. Depending on the frequency range, it provides fully adjustable resolution bandwidth from less than 1 Hz to 10 MHz and enables equalized bandwidths ranging from 10 MHz to 50 MHz. The 10 MHz internal frequency reference ensures accurate readings with an aging rate of ±5 × 10^-6 per year and temperature stability of ±1 × 10^-6.
Spectral purity-wise, the 781259-01 has a typical phase noise of -105 dBc/Hz at 1 GHz. Its RF input attenuation may be adjusted in 1 dB steps from 0 dB to 50 dB, and its amplitude range covers the average noise level up to +30 dBm. When attenuation is turned on, the PXIe-5601 module, which facilitates the RF input, can safely manage a constant RF power level of +30 dBm using a SMA female connector with a 50 Ω impedance.
The 781259-01 exhibits an excellent dynamic range, offering nominal performance with third-order intermodulation distortion (IMD3) over a wide range of frequency bands. It may be stored in temperatures between -40 °C and 71 °C and performs effectively in the ambient temperature range of 0 °C to 55 °C. Its design emphasizes durability and dependability. This part satisfies strict performance and safety requirements thanks to compliance with safety standards like IEC 61010-1 and EMC standards like EN 61326-1. This makes it a great option for sophisticated signal analysis in demanding applications.
