This 3U module occupies two slots in the PXI chassis and utilizes VCO-based synthesizer technology, implemented through QuickSyn® technology, enabling rapid settling times of typically 300 µs and a fine tuning resolution of less than 1 Hz. It is particularly well-suited for applications involving signal intelligence, synthetic instrumentation, or microwave receivers, facilitating the down conversion of microwave signals to baseband frequencies. The PXI-1450B features a single RF output with a frequency range from 3 to 9 GHz, a frequency step size of 0.1 Hz, and a switching speed of 500 µs. Spectral purity is maintained with harmonics of -12 dBc and non-harmonic spurious levels reaching -70 dBc nominal. The module supports an external master reference oscillator and employs an ovenized crystal oscillator, allowing it to distribute an internal high-stability reference across other modules within the PXI environment. Internally, the PXI-1450B consumes DC power at rates of 0.5 A for +3.3 V and +5 V, 0.75 A for +12 V, and 0.1 A for -12 V, with a maximum power dissipation of 16 W. Designed for environments ranging from 0˚ to 55˚ C during operation and from -40˚ to 70˚ C when stored, the module has a warm-up time of no more than 15 minutes before use. The PXI-1450B weighs 2 lbs (0.91 kg) and serves as a vital component of the National Instruments PXI-1470 Vector Signal Analyzer, incorporating a robust design for enhanced microwave applications.\u003c\/p\u003e","brand":"National Instruments","offers":[{"title":"Default Title","offer_id":46683858862316,"sku":"PXI-1450B","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/National_Instruments_Group_Photo_-_Final_Compressed_56c3a03b-5e70-4aea-9e32-7b03e585123b.jpg?v=1753243142","url":"https:\/\/www.industrialautomationco.com\/products\/national-instruments-pxi-1450b","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
