PXIe‑5646R | 6 GHz 200 MHz User-Programmable FPGA Vector Signal Transceiver (VST)

PN：  784759-01
The PXIe‑5646R is a three-slot 3U PXI Express all-in-one software-defined RF vector signal transceiver, integrating complete vector signal generator (VSG), vector signal analyzer (VSA), high-speed digital I/O and large-capacity user-customizable Xilinx Virtex-6 LX240T FPGA, eliminating separate RF source and receiver cards to minimize test rack footprint for wideband wireless R&D and mass-production ATE.
RF frequency coverage spans 65 MHz to 6 GHz, fully supporting WiFi 802.11ax 160 MHz, LTE-A carrier aggregation, GNSS, sub-GHz IoT and short-range radar signals. Industry-leading 200 MHz digitally equalized real-time instantaneous bandwidth on both transmit and receive paths captures full wideband signal frames without segmented sweep stitching, drastically cutting single-DUT test cycle time. Transmit typical max CW output power +18 dBm, low phase noise (-112 dBc/Hz @1 GHz, 10 kHz offset) delivers lab-grade modulation accuracy for high-order MIMO communication devices.
16-bit transmit DAC / 14-bit receive ADC, onboard hardware DUC/DDC IP cores offload baseband I/Q processing to FPGA hardware. Equipped with 24-channel bidirectional high-speed DIO (max 250 Mbps) for parallel digital baseband validation of RF front-end chips. Front-panel SMA ports include RF IN, RF OUT, CAL IN/OUT, independent LO I/O, 10 MHz reference clock and PFI trigger; all RF ports fixed 50 Ω AC-coupled impedance matching standard RF test fixtures.
Massive Virtex-6 LX240T FPGA + 1 GB onboard DRAM enable hardware acceleration of real-time DPD digital pre-distortion, radar pulse compression, custom demodulation, closed-loop power amplifier control and BER calculation, achieving microsecond deterministic latency unreachable by fixed-function bench instruments. Native NI-TClk multi-card synchronization provides sub-nanosecond phase alignment to build scalable 2×2 / 4×4 coherent MIMO multi-antenna test benches. Controlled by unified NI-RFmx, NI-RFSG and NI-RFSA drivers, compatible with Windows and LabVIEW Real-Time OS, widely deployed for wideband wireless chip parametric validation, power amplifier linearity test, SDR prototype research and automotive telematics ECU hardware-in-the-loop simulation.

Core Functional Advantages

All-in-one VSG+VSA+DIO three-slot integrated architecture reduces cabinet space occupation by over 40% compared to discrete generator + digitizer combinations, perfectly suited for compact mass-production ATE racks. 200 MHz ultra-wide instantaneous bandwidth fully meets 160 MHz WiFi 6 and LTE-A carrier aggregation full-signal test requirements, removing time-consuming segmented sweep stitching and greatly boosting test throughput.
Large user-accessible Virtex-6 FPGA + 1 GB DRAM offloads all real-time RF processing logic to hardware, realizing microsecond-latency closed-loop DPD power amplifier linearization test unavailable with software-timed standard RF instruments. 24-channel high-speed DIO completes RF analog performance and digital baseband interface validation in one station without external digital test hardware.
Independent front-panel LO input/output ports support external wideband downconverters/upconverters to extend frequency coverage to K-band radar. NI-TClk seamless multi-VST synchronization builds scalable MIMO multi-antenna test systems without external clock distribution hardware. Complete NI-RFmx measurement library delivers one-click EVM, ACPR, spectrum, channel power and spurious analysis function blocks, significantly shortening LabVIEW wideband wireless automated test development cycle compared to standalone bench VSAs/VSGs. Compact modular design reserves abundant expansion slots for RF switching matrices, source measure units and multi-channel DAQ sensors.
