The National Instruments part number 780485-01 corresponds to the PXIe-5673E PXI Vector Signal Generator, which operates at frequencies up to 6.6 GHz and is equipped with a MIMO extension kit. This product does not represent a standalone module but rather integrates the functionality of several modules: the NI PXIe-5450/5451 arbitrary waveform generator, the NI PXIe-5650/5651/5652 local oscillator source, and the NI PXIe-5611 I/Q modulator. With 512 MB of onboard memory, the 780485-01 supports a wide range of testing applications. A variant with 128 MB of RAM is available under part number 780485-02. The MIMO extension enables enhanced signal bandwidth, optimizing performance in complex testing scenarios. When fully configured, the front panel of the signal generator features 19 connectors and 6 LED indicators, allowing for comprehensive monitoring and connectivity. The device is designed to withstand operational shock of up to 30 g and random vibrations from 5 Hz to 500 Hz. Intended for indoor use, it operates efficiently within a temperature range of 0 °C to 55 °C and relative humidity levels of 10% to 90% (non-condensing). For storage, it can endure a broader temperature range of -40 °C to 71 °C with humidity levels from 5% to 95% (non-condensing). Weighing 1,458 g (52 oz), the PXIe-5673E is backed by a three-year warranty, ensuring reliability for demanding applications.
