6 GHz, 200 MHz Bandwidth, RF PXI Vector Signal Transceiver—The PXIe‑5646 combines a vector signal generator and vector signal analyzer with FPGA-based real-time signal processing and control into a single device, also known as a VST. Because of this software-designed approach, the PXIe‑5646 features the flexibility of a software defined radio architecture with RF instrument class performance. The additional bandwidth of the PXIe‑5646 enables you to test wireless and cellular standards such as 802.11ac 160 MHz and LTE‑A carrier aggregation while leveraging the latest performance-enhancing processing techniques such as digital predistortion.
