Verify radio-head quantity, direct or switched port arrangement, cable set and required frequency coverage before ordering.<\/p>\n<h3>PXIe-5831 System Architecture<\/h3>\n<h4>PXIe-5820 Baseband Vector Signal Transceiver<\/h4>\n<p>The PXIe-5820 provides high-speed baseband waveform generation, acquisition and FPGA processing. It forms the digital foundation of the configured PXIe-5831 instrument.<\/p>\n<h4>PXIe-3622 Upconverter and Downconverter<\/h4>\n<p>The PXIe-3622 converts between the baseband and 5 GHz to 21 GHz intermediate-frequency range. IF ports can be used directly or connected to the mmWave conversion hardware.<\/p>\n<h4>PXIe-5653 Local-Oscillator Source<\/h4>\n<p>The PXIe-5653 provides the local-oscillator signal used in applicable mmWave configurations. Proper cable installation and frequency-reference synchronization are essential for specified performance.<\/p>\n<h4>mmRH-5582 Radio Head<\/h4>\n<p>The mmRH-5582 performs frequency conversion close to the DUT. Positioning the radio head near the test fixture reduces high-frequency cable loss and helps maintain mmWave measurement performance.<\/p>\n<h3>1 \u0413\u0413\u0446 \u043c\u0433\u043d\u043e\u0432\u0435\u043d\u043d\u043e\u0439 \u043f\u043e\u043b\u043e\u0441\u044b \u043f\u0440\u043e\u043f\u0443\u0441\u043a\u0430\u043d\u0438\u044f<\/h3>\n<p>The PXIe-5831 can generate and acquire as much as 1 GHz of instantaneous bandwidth. This supports wide 5G NR carriers, broadband radar chirps, multi-carrier signals and wideband component measurements.<\/p>\n<p>Actual usable bandwidth depends on center frequency, selected port, offset mode, software configuration and calibration state.<\/p>\n<h3>Direct and Switched TRX Ports<\/h3>\n<p>Direct TRX ports provide a short RF path for applications prioritizing signal performance. Switched port banks allow one instrument to route signals between several DUT connections, improving test density and reducing external mmWave switching hardware.<\/p>\n<p>The number of direct and switched ports depends on the ordered mmRH-5582 and PXIe-5831 system configuration.<\/p>\n<h3>5G NR FR2 Testing<\/h3>\n<p>The PXIe-5831 can generate and analyze wideband signals used in 5G NR mmWave testing. RFmx NR software can provide measurements such as channel power, occupied bandwidth, adjacent-channel leakage ratio and modulation accuracy.<\/p>\n<p>Multiple systems can be synchronized for MIMO, phased-array or multi-site testing. Complete system accuracy depends on cable phase matching, calibration and radio-head placement.<\/p>\n<h3>Radar and Phased-Array Testing<\/h3>\n<p>The wide bandwidth supports radar pulses, chirps and complex modulated waveforms. Engineers can use FPGA processing for custom triggering, pulse detection, data reduction and low-latency control.<\/p>\n<p>Radio heads can be positioned close to beamformer or antenna-array interfaces to reduce cable loss at millimeter-wave frequencies.<\/p>\n<h3>Typical PXIe-5831 Applications<\/h3>\n<ul>\n<li>5G NR FR2 transmitter and receiver testing<\/li>\n<li>mmWave RFIC characterization<\/li>\n<li>Front-end-module production test<\/li>\n<li>Phased-array and beamformer validation<\/li>\n<li>Over-the-air antenna testing<\/li>\n<li>Radar waveform generation and analysis<\/li>\n<li>Wi-Fi 6 and wideband wireless testing<\/li>\n<li>Semiconductor wafer and final test<\/li>\n<li>Multi-site mmWave production testing<\/li>\n<li>Phase-coherent MIMO systems<\/li>\n<\/ul>\n<h3>PXIe-5831 Software Support<\/h3>\n<p>NI-RFSA and NI-RFSG provide analyzer and generator control. RFmx offers spectrum and standards-based measurement personalities. InstrumentStudio can be used for interactive setup and initial verification.<\/p>\n<p>Compatible FPGA development tools allow engineers to implement customized real-time processing and test functions on the PXIe-5820 FPGA.<\/p>\n<h3>PXIe-5831 Calibration and Cooling<\/h3>\n<p>The system should be allowed to warm up before self-calibration. All component temperatures should remain within the required range of the last calibration temperature.<\/p>\n<p>Applicable modules require a chassis with 82 W slot cooling capacity. Install slot blockers and EMC filler panels in unused positions and configure the recommended chassis cooling profile.<\/p>\n<h3>PXIe-5831 Troubleshooting<\/h3>\n<h4>The PXIe-5831 does not appear as one instrument<\/h4>\n<p>Confirm that every component module is detected and that the required RF drivers are installed. Inspect all IF, I\/Q, LO and control cables.<\/p>\n<h4>The radio head is not detected<\/h4>\n<p>Check the radio-head interface cable, power, connector seating and system configuration. Confirm that the connected radio-head type matches the configured instrument.<\/p>\n<h4>RF output power is lower than expected<\/h4>\n<p>Inspect the mmWave connectors and cables, confirm the selected direct or switched port and perform self-calibration. Cable loss becomes significant at high frequencies.<\/p>\n<h4>Measurements change after warm-up<\/h4>\n<p>Wait for thermal stabilization and repeat self-calibration. Verify chassis airflow, slot cooling and the temperature of every system module.<\/p>\n<h4>The required transmit frequency is unavailable<\/h4>\n<p>Check the exact PXIe-5831 hardware revision and system configuration. Some PXIe-5831 configurations have a transmit gap between 31.3 GHz and 37 GHz.<\/p>\n<h3>PXIe-5831 vs PXIe-5832<\/h3>\n<table>\n<tbody>\n<tr>\n<th>\u0424\u0443\u043d\u043a\u0446\u0438\u044f<\/th>\n<th>PXIe-5831<\/th>\n<th><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-5832\/\">PXIe-5832<\/a><\/th>\n<\/tr>\n<tr>\n<td>\u041c\u0430\u043a\u0441\u0438\u043c\u0430\u043b\u044c\u043d\u0430\u044f \u0447\u0430\u0441\u0442\u043e\u0442\u0430<\/td>\n<td>44 GHz<\/td>\n<td>44 GHz<\/td>\n<\/tr>\n<tr>\n<td>Maximum Bandwidth<\/td>\n<td>1 GHz<\/td>\n<td>1 GHz<\/td>\n<\/tr>\n<tr>\n<td>IF Range<\/td>\n<td>5 GHz to 21 GHz<\/td>\n<td>5 GHz to 21 GHz<\/td>\n<\/tr>\n<tr>\n<td>mmWave Receive Coverage<\/td>\n<td>22.5 GHz to 44 GHz<\/td>\n<td>22.5 GHz to 44 GHz<\/td>\n<\/tr>\n<tr>\n<td>mmWave Transmit Coverage<\/td>\n<td>Configuration dependent; original specifications include a 31.3 GHz to 37 GHz gap<\/td>\n<td>Continuous 22.5 GHz to 44 GHz<\/td>\n<\/tr>\n<tr>\n<td>Best Suited For<\/td>\n<td>Existing PXIe-5831 systems and configured multiport test<\/td>\n<td>Continuous mmWave transmit and receive coverage<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Recommended Related Products<\/h3>\n<ul>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-5832\/\">PXIe-5832 44 GHz mmWave Vector Signal Transceiver<\/a><\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-5840\/\">PXIe-5840 Wideband Vector Signal Transceiver<\/a><\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-5841\/\">PXIe-5841 Vector Signal Transceiver<\/a><\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-5653\/\">PXIe-5653 RF Analog Signal Generator<\/a><\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product-category\/%d0%bd%d0%b8\/pxi-%d1%81%d0%b8%d1%81%d1%82%d0%b5%d0%bc%d1%81\/%d0%bc%d0%be%d0%b4%d1%83%d0%bb%d0%b8-pxi\/\">View More NI PXI Express Modules<\/a><\/li>\n<\/ul>\n<h3>Frequently Asked Questions<\/h3>\n<h4>Is the PXIe-5831 a single module?<\/h4>\n<p>No. PXIe-5831 identifies a configured instrument system consisting of multiple PXI Express modules and optional mmWave radio heads.<\/p>\n<h4>What is the maximum frequency?<\/h4>\n<p>The system supports operation as high as 44 GHz.<\/p>\n<h4>What is the instantaneous bandwidth?<\/h4>\n<p>The PXIe-5831 provides up to 1 GHz of instantaneous bandwidth.<\/p>\n<h4>Can it test 5G NR FR2 devices?<\/h4>\n<p>Yes.
