Features<\/h3>\n<h4>High-Density PXI Switching<\/h4>\n<p>\nThe PXI-2533 provides a high-density switching architecture for PXI automated test systems.\n<\/p>\n<p>\nHigh channel density is particularly valuable when many DUT test points must share a smaller number of measurement instruments.\n<\/p>\n<p>\nInstead of dedicating an instrument to every test point, the switch can dynamically connect the required signal to the appropriate instrument.\n<\/p>\n<h4>4\u00d764 1-Wire Multiplexer Configuration<\/h4>\n<p>\nOne of the primary configurations of the PXI-2533 is a <strong>4\u00d764 1-wire multiplexer<\/strong>.\n<\/p>\n<p>\nThis topology provides four independent multiplexer banks with 64 channels per bank, allowing a large number of signals to be routed within a single PXI switching module.\n<\/p>\n<p>\nA typical measurement architecture can be represented as:\n<\/p>\n<p>\n<strong>Multiple DUT Signals \u2192 PXI-2533 \u2192 Measurement Instrument \u2192 Test Software<\/strong>\n<\/p>\n<h4>256-Crosspoint Matrix Architecture<\/h4>\n<p>\nThe PXI-2533 can also be configured as a <strong>256-crosspoint matrix<\/strong>, providing flexible signal-routing capability for applications where connections must be dynamically established between multiple signal paths.\n<\/p>\n<p>\nMatrix switching is useful for:\n<\/p>\n<ul>\n<li>Flexible DUT routing<\/li>\n<li>Automated functional testing<\/li>\n<li>Multi-instrument test systems<\/li>\n<li>Signal path reconfiguration<\/li>\n<li>Research and development<\/li>\n<li>Production validation<\/li>\n<\/ul>\n<h4>Configurable Switching Topologies<\/h4>\n<p>\nThe PXI-2533 supports multiple switching topologies, allowing engineers to optimize the module for different test requirements.\n<\/p>\n<p>\nDepending on the system configuration, the switch can be used for high-density multiplexing or matrix-based signal routing.\n<\/p>\n<p>\nThis flexibility can reduce the number of separate switching modules required in complex automated test systems.\n<\/p>\n<h4>Solid-State FET Switching<\/h4>\n<p>\nThe PXI-2533 uses <strong>field-effect transistor (FET) switching technology<\/strong> rather than conventional electromechanical relays.\n<\/p>\n<p>\nFET switching provides important advantages for applications requiring frequent switching operations.\n<\/p>\n<ul>\n<li>Fast switching<\/li>\n<li>No mechanical relay contacts<\/li>\n<li>High switching-cycle capability<\/li>\n<li>Quiet operation<\/li>\n<li>Suitable for repetitive automated testing<\/li>\n<li>Compact high-density switching architecture<\/li>\n<\/ul>\n<h4>Fast Automated Signal Routing<\/h4>\n<p>\nBecause the PXI-2533 uses solid-state switching, signal paths can be changed rapidly under software control.\n<\/p>\n<p>\nFast switching is particularly valuable in production test systems where hundreds or thousands of switching operations may occur during repeated test sequences.\n<\/p>\n<h4>Software-Controlled Switching<\/h4>\n<p>\nThe PXI-2533 can be controlled programmatically as part of an automated PXI test system.\n<\/p>\n<p>\nTest software can

Is a PXI Multiplexer Switch?<\/h3>\n<p>\nA PXI multiplexer switch allows multiple input signals to share one or more measurement instruments.\n<\/p>\n<p>\nFor example, a test system may need to measure voltage at dozens of DUT test points using a single digital multimeter.\n<\/p>\n<p>\nInstead of installing a separate DMM for every measurement point, the system can use a PXI switch:\n<\/p>\n<p>\n<strong>DUT Channels \u2192 PXI-2533 \u2192 PXI DMM \u2192 Measurement Software<\/strong>\n<\/p>\n<p>\nThe PXI-2533 selects the required DUT channel, routes it to the measurement instrument, and then changes to the next channel according to the automated test sequence.\n<\/p>\n<h3>What Is a Matrix Switch?<\/h3>\n<p>\nA matrix switch provides flexible connections between multiple signal paths.\n<\/p>\n<p>\nUnlike a basic multiplexer, which typically selects one channel from a group, a matrix architecture can provide more flexible routing between rows and columns.\n<\/p>\n<p>\nThis makes matrix switching useful when an automated test system needs to dynamically change connections between DUT signals and test equipment.\n<\/p>\n<h3>Multiplexer vs Matrix

requirements.\n<\/p>\n<h3>High-Channel-Count Data Acquisition<\/h3>\n<p>\nThe PXI-2533 can be used to expand the number of signals that can be measured by a data acquisition or measurement instrument.\n<\/p>\n<p>\nA typical architecture can be represented as:\n<\/p>\n<p>\n<strong>64+ Sensors \/ Test Points \u2192 PXI-2533 \u2192 DAQ or DMM \u2192 PXI Controller<\/strong>\n<\/p>\n<p>\nThe switch sequentially routes signals to the measurement instrument, allowing one instrument to acquire data from many test points.\n<\/p>\n<h3>Digital Multimeter Signal Routing<\/h3>\n<p>\nOne of the most common applications for high-density PXI switching is routing signals to a digital multimeter.\n<\/p>\n<p>\nA PXI DMM combined with the PXI-2533 can create a high-channel-count measurement system for:\n<\/p>\n<ul>\n<li>DC voltage measurements<\/li>\n<li>Resistance measurements<\/li>\n<li>Continuity testing<\/li>\n<li>Component validation<\/li>\n<li>Production test<\/li>\n<li>Functional testing<\/li>\n<\/ul>\n<p>\nThe exact measurement capability depends on the DMM, switch topology, signal characteristics, and system configuration.\n<\/p>\n<h3>Automated Functional Testing<\/h3>\n<p>\nFunctional test systems frequently need to connect different DUT nodes to measurement or stimulus instruments during different stages of a test sequence.\n<\/p>\n<p>\nThe PXI-2533 can automate these routing operations.\n<\/p>\n<p>\n\u041d\u0430\u043f\u0440\u0438\u043c\u0435\u0440:\n<\/p>\n<ol>\n<li>Connect DUT test point A to the measurement instrument.<\/li>\n<li>Perform the required measurement.<\/li>\n<li>Disconnect test point A.<\/li>\n<li>Connect test point B.<\/li>\n<li>Perform the next measurement.<\/li>\n<li>Continue through the automated sequence.<\/li>\n<\/ol>\n<p>\nThis approach reduces manual wiring and improves test repeatability.\n<\/p>\n<h3>Production Test Applications<\/h3>\n<p>\nProduction test systems require fast, repeatable, and reliable switching between DUT test points.\n<\/p>\n<p>\nThe FET-based PXI-2533 is particularly suitable for applications involving frequent switching operations.\n<\/p>\n<p>\nTypical production applications include:\n<\/p>\n<ul>\n<li>PCB functional testing<\/li>\n<li>Electronic assembly testing<\/li>\n<li>Device validation<\/li>\n<li>Continuity testing<\/li>\n<li>Automated measurement routing<\/li>\n<li>Manufacturing test fixtures<\/li>\n<li>End-of-line testing<\/li>\n<\/ul>\n<h3>Semiconductor Test Applications<\/h3>\n<p>\nSemiconductor characterization and production test systems often require flexible routing between DUT pins and measurement instruments.\n<\/p>\n<p>\nThe PXI-2533 can provide high-density signal switching within compatible semiconductor test architectures.\n<\/p>\n<p>\nPotential applications include:\n<\/p>\n<ul>\n<li>Device characterization<\/li>\n<li>Pin routing<\/li>\n<li>Continuity measurements<\/li>\n<li>Functional validation<\/li>\n<li>Automated production testing<\/li>\n<li>Multi-device test fixtures<\/li>\n<\/ul>\n<h3>Electronic Validation<\/h3>\n<p>\nDuring electronic product development, engineers may need to measure many internal signals using a limited number of instruments.\n<\/p>\n<p>\nThe PXI-2533 allows test software to dynamically connect selected test points to the appropriate measurement instrument.\n<\/p>\n<p>\nThis makes the module useful for:\n<\/p>\n<ul>\n<li>Design verification<\/li>\n<li>Board-level validation<\/li>\n<li>Prototype testing<\/li>\n<li>Subsystem validation<\/li>\n<li>Automated regression testing<\/li>\n<\/ul>\n<h3>Reducing Instrument Count<\/h3>\n<p>\nA switching system can reduce the number of measurement instruments required for high-channel-count testing.\n<\/p>\n<p>\nFor example, instead of using 64 separate voltage measurement channels, a multiplexer can route 64 DUT signals sequentially to a smaller number of precision measurement instruments.\n<\/p>\n<p>\nThis can reduce:\n<\/p>\n<ul>\n<li>System hardware cost<\/li>\n<li>Rack space<\/li>\n<li>Instrument count<\/li>\n<li>System complexity<\/li>\n<li>Calibration requirements<\/li>\n<\/ul>\n<h3>PXI-2533 in a Complete PXI System<\/h3>\n<p>\nThe PXI-2533 is typically used as the signal-routing layer within a complete PXI automated test platform.\n<\/p>\n<p>\nA system may include:\n<\/p>\n<ul>\n<li>\u0428\u0430\u0441\u0441\u0438 PXI<\/li>\n<li>PXI embedded or remote controller<\/li>\n<li>PXI-2533

unit<\/li>\n<li>Digital I\/O modules<\/li>\n<li>Additional switching modules<\/li>\n<\/ul>\n<p>\nThis architecture allows measurement, stimulus, switching, data acquisition, and control functions to be integrated into one modular test platform.\n<\/p>\n<h3>Typical Automated Measurement Architecture<\/h3>\n<p>\nA high-channel-count automated measurement system using the PXI-2533 may operate as follows:\n<\/p>\n<p>\n<strong>DUT Test Points \u2192 PXI-2533 Switch \u2192 PXI DMM \/ DAQ \u2192 PXI Controller \u2192 Test Software<\/strong>\n<\/p>\n<p>\nThe software controls both the switch and measurement instrument, allowing each DUT signal to be measured automatically according to the required test sequence.\n<\/p>\n<h3>Software Integration<\/h3>\n<p>\nThe PXI-2533 can be integrated into NI software-based automated test environments.\n<\/p>\n<p>\nTypical software applications may use:\n<\/p>\n<ul>\n<li>NI-SWITCH<\/li>\n<li>\u041b\u0430\u0431\u0412\u044c\u044e<\/li>\n<li>LabWindows\/CVI<\/li>\n<li>\u0422\u0435\u0441\u0442\u043e\u0432\u0430\u044f \u0441\u0442\u043e\u0439\u043a\u0430<\/li>\n<li>Compatible programming environments<\/li>\n<\/ul>\n<p>\nNI-SWITCH provides software control for compatible NI switch modules and allows applications to configure routes and manage switching operations programmatically.\n<\/p>\n<h3>Switch Executive Integration<\/h3>\n<p>\nIn complex automated test systems, NI Switch Executive can be used with compatible switching hardware to simplify route configuration and management.\n<\/p>\n<p>\nInstead of controlling individual relay or FET connections directly, engineers can define logical routes and use software to manage the underlying switching configuration.\n<\/p>\n<p>\nThis can simplify development when a system contains multiple switching modules and many interconnected signal paths.\n<\/p>\n<h3>Important Signal Considerations<\/h3>\n<p>\nBefore selecting the PXI-2533 for a test application, engineers should verify that the characteristics of the signal are compatible with the switch module.\n<\/p>\n<p>\nImportant parameters include:\n<\/p>\n<ul>\n<li>Maximum switching voltage<\/li>\n<li>Maximum switching current<\/li>\n<li>Maximum switching power<\/li>\n<li>On resistance<\/li>\n<li>\u041f\u0440\u043e\u043f\u0443\u0441\u043a\u043d\u0430\u044f \u0441\u043f\u043e\u0441\u043e\u0431\u043d\u043e\u0441\u0442\u044c<\/li>\n<li>Leakage current<\/li>\n<li>Signal frequency<\/li>\n<li>Required switching speed<\/li>\n<li>Topology requirements<\/li>\n<\/ul>\n<p>\nThese parameters are particularly important for FET-based switches because their electrical characteristics differ from electromechanical relay switches.\n<\/p>\n<h3>FET Switch vs Relay Switch Selection<\/h3>\n<p>\nThe PXI-2533 is optimized for high-density, fast, repetitive switching applications. It is not automatically the best choice for every signal-routing requirement.\n<\/p>\n<p>\nAn electromechanical relay-based PXI switch may be more appropriate when an application requires higher voltage, higher current, very low leakage, or different isolation characteristics.\n<\/p>\n<p>\nThe PXI-2533 is particularly attractive when the priorities are:\n<\/p>\n<ul>\n<li>High channel density<\/li>\n<li>Fast switching<\/li>\n<li>Very high switching-cycle requirements<\/li>\n<li>Compact PXI integration<\/li>\n<li>Automated low-voltage signal

PXI multiplexer and matrix switch module designed for automated signal routing in test and measurement systems.\n<\/p>\n<h4>What type of switch does the PXI-2533 use?<\/h4>\n<p>\nThe PXI-2533 uses <strong>solid-state FET switching technology<\/strong>.\n<\/p>\n<h4>What is the main topology of the PXI-2533?<\/h4>\n<p>\nOne of the primary PXI-2533 configurations is a <strong>4\u00d764 1-wire multiplexer<\/strong>. The module also supports configurable matrix-based signal-routing applications.\n<\/p>\n<h4>What does 4\u00d764 1-wire mean?<\/h4>\n<p>\nA 4\u00d764 1-wire configuration provides four multiplexer banks with 64 signal channels per bank. It is designed for high-density routing of single-wire signals to common measurement paths.\n<\/p>\n<h4>What does 256-crosspoint matrix mean?<\/h4>\n<p>\nA crosspoint represents a programmable connection within a switching matrix. A 256-crosspoint architecture provides a large number of software-controlled connection points for flexible signal routing.\n<\/p>\n<h4>Is the PXI-2533 a mechanical relay switch?<\/h4>\n<p>\nNo. The PXI-2533 uses semiconductor FET switches rather than conventional electromechanical relay contacts.\n<\/p>\n<h4>What are the advantages of FET switching?<\/h4>\n<p>\nFET switches provide fast switching, no mechanical contact wear, high switching-cycle capability, and high channel density. These characteristics make them particularly useful for repetitive automated test applications.\n<\/p>\n<h4>Can the PXI-2533 be used with a digital multimeter?<\/h4>\n<p>\nYes. One common application is routing multiple DUT signals to a shared PXI or external digital multimeter. The complete signal requirements should be checked against the specifications of both the switch and DMM.\n<\/p>\n<h4>Can the PXI-2533 be used with a DAQ module?<\/h4>\n<p>\nYes. The PXI-2533 can be used as a signal-routing layer for compatible data acquisition applications where multiple signals must share measurement channels.\n<\/p>\n<h4>Can the PXI-2533 be used for production testing?<\/h4>\n<p>\nYes. Its high channel density, software-controlled routing, and solid-state switching architecture make it suitable for repetitive automated production test applications.\n<\/p>\n<h4>Can the PXI-2533 be used for semiconductor testing?<\/h4>\n<p>\nYes. The module can be used in compatible semiconductor characterization and automated test systems requiring high-density signal routing.\n<\/p>\n<h4>What software is used with the PXI-2533?<\/h4>\n<p>\nThe PXI-2533 can be controlled using NI switching software such as NI-SWITCH and integrated into automated applications developed with LabVIEW, TestStand, LabWindows\/CVI, and other compatible programming environments.\n<\/p>\n<h4>Is the PXI-2533 suitable for high-voltage switching?<\/h4>\n<p>\nThe PXI-2533 is primarily optimized for high-density FET-based signal routing rather than high-voltage power switching. Engineers should verify the signal voltage, current, power, and isolation requirements against the official hardware specifications before connecting a DUT.\n<\/p>\n<h4>What is the difference between a PXI multiplexer and a PXI matrix switch?<\/h4>\n<p>\nA multiplexer is typically used to select one or more signals from a larger group and route them to common measurement paths. A matrix provides more flexible connections between multiple rows and columns. The PXI-2533 supports configurable switching architectures for different automated test requirements.\n<\/p>\n<h4>What applications are suitable for the PXI-2533?<\/h4>\n<p>\nTypical applications include high-channel-count data acquisition, DMM signal routing, automated functional test, PCB validation, production testing, semiconductor test, electronic validation, and other systems requiring programmable signal switching.\n<\/p>\n<h4>What should I check before purchasing a PXI-2533?<\/h4>\n<p>\nBefore purchasing a PXI-2533, verify the required switching topology, number of channels, signal voltage, current, power, bandwidth, on resistance, leakage requirements, switching speed, connector and terminal block requirements, PXI chassis compatibility, and NI-SWITCH software compatibility.\n<\/p>\n<h3>\u0417\u0430\u043a\u043b\u044e\u0447\u0435\u043d\u0438\u0435<\/h3>\n<p>\n\u0417\u0435\u043c\u043b\u044f <strong>NI PXI-2533 High-Density PXI Multiplexer Switch Module<\/strong> provides flexible FET-based signal routing for automated test and measurement systems.
