NI PXIe-5611

NI identifies the PXIe-5611 as a “6.6 GHz PXI I/Q Modulator,” and NI’s PXIe-5673/5673E overview describes it as a “6.6 GHz I/Q modulator PXI Express module.” NI-RFSG documentation also refers to the PXIe-5611 as the upconverter. https://www.ni.com/en/shop/hardware/upconverters/model-pxie-5611 https://www.ni.com/docs/en-US/bundle/pxie-5673-5673e-features/page/overview.html

NI states that the PXIe-5611 provides I/Q modulation when used as part of a PXIe-5673/5673E vector signal generator. The PXIe-5673/5673E overview further clarifies that there is no physical device labeled “PXIe-5673” or “PXIe-5673E”; those are composite instruments built from modules including the PXIe-5611. https://www.ni.com/en/shop/hardware/upconverters/model-pxie-5611 https://www.ni.com/docs/en-US/bundle/pxie-5673-5673e-features/page/overview.html

Model identification is supported at both the commercial and assembly levels in NI documentation. NI’s product page lists orderable product number 780277-01 for the PXIe-5611, while NI certification and volatility documents reference module assembly identifiers 196385-01L and 196385X-01L. Based on the reviewed NI sources, these identify the same base PXIe-5611 model rather than different functional variants. https://www.ni.com/en/shop/hardware/upconverters/model-pxie-5611 https://www.ni.com/en/support/documentation/product-certifications/model.pxie-5611.html https://download.ni.com/pub/gdc/tut/pxie-5611_lov.pdf
