National Instruments PXI-5671 PXI Vector Signal Generator

The PXI-5671 Vector Signal Generator (Part Numbers: 779079-02, 779079-03, and 779079-04) is not a singular model, but instead describes the interconnected use of the PXI-5441 Waveform Generator and the PXI-5610 RF Signal Upconverter. The PXI-5671 is controlled by the NI-RFSG instrument controller and accompanies the Modulation Toolkit for LabVIEW. NI-RFSG is a practical instrument driver, perfect with an assortment of use programming conditions, such as NI LabVIEW 7 Express, LabWindows/CVI, and C. NI-RFSG introduces simple-to-utilize highlights to set the time and synchronization, CW tone, and self-assertive generation of the NI PXI-5671 waveform capacities.

The Modulation Toolkit for LabVIEW offers capacities to signal generation, examination, and visualization of custom and standard simple and computerized modulation. With the Modulation Toolkit, the user can create and analyze custom modulation formats. A portion of the standard estimation capacities incorporate EVM (error vector magnitude), MER (modulation error ratio), and ρ (rho). Capacities are additionally accessible for injecting impairments including IQ Gain Imbalance, Quadrature Skew, and AWGN (additive white Gaussian noise). Visualization capacities incorporate trellis, constellation, and 2D-and 3D-eye diagrams. This equipment and programming mix gives the user access to adaptable usefulness not accessible in conventional instrumentation.

The PXI-5671 has 3 onboard memory options: 32 MB (part number 779079-02), 256 MB (part number 779079-03), and 512 MB (part number 779079-04). The deep memory of 256 MB maximum available with the PXI-5671 offers broadened playback time for complex regulated signals. With this deep memory, the user can assemble and output longer and more unpredictable waveforms with a span as long as 1.28 seconds to address research and testing requirements for the simulation of signal transmission in real-world conditions.
