It provides a scalable architecture for building high-density switching systems used in automated test, semiconductor test, electronic validation, production test, and other applications requiring large programmable switch matrices.\n<\/p>\n<p>\nThe PXI-2800 occupies four PXI slots and can accommodate up to <strong>six NI SwitchBlock relay cards<\/strong>. By connecting multiple SwitchBlock cards through the carrier&#8217;s integrated analog bus, engineers can create large and flexible switching matrices while maintaining a compact PXI system footprint.\n<\/p>\n<p>\nA single PXI-2800 can support switch configurations with <strong>more than 2,000 crosspoints within four PXI slots<\/strong>. Multiple SwitchBlock carriers can be used to build systems with <strong>more than 8,000 crosspoints in a single PXI chassis<\/strong>, making the platform particularly suitable for high-channel-count automated test systems.\n<\/p>\n<h3>Product Overview<\/h3>\n<p>\n\u0417\u0435\u043c\u043b\u044f <strong>National Instruments PXI-2800<\/strong> serves as the hardware carrier and interconnection platform for compatible NI SwitchBlock relay cards.\n<\/p>\n<p>\nUnlike a conventional PXI switch module with a fixed relay topology, the PXI-2800 allows engineers to install different compatible SwitchBlock cards according to the required matrix architecture, signal characteristics, channel count, and switching performance.\n<\/p>\n<ul>\n<li>4-slot PXI carrier module<\/li>\n<li>Designed for

architecture<\/li>\n<li>Designed for high-density automated test systems<\/li>\n<\/ul>\n<h3>Key Features<\/h3>\n<h4>4-Slot PXI Carrier Module<\/h4>\n<p>\nThe PXI-2800 occupies <strong>four PXI slots<\/strong> within a compatible PXI chassis.\n<\/p>\n<p>\nThese four slots provide the physical carrier architecture required to install and operate multiple SwitchBlock relay cards as one integrated switching system.\n<\/p>\n<p>\nThis architecture provides significantly greater switching density than many conventional individual PXI switch modules.\n<\/p>\n<h4>Supports Up to Six SwitchBlock Relay Cards<\/h4>\n<p>\nA single PXI-2800 carrier can accommodate up to <strong>six compatible NI SwitchBlock relay cards<\/strong>.\n<\/p>\n<p>\nThis allows engineers to select relay cards according to the specific requirements of the test system rather than being limited to one fixed switching configuration.\n<\/p>\n<p>\nDepending on the selected SwitchBlock cards, systems can be optimized for:\n<\/p>\n<ul>\n<li>High-density matrix switching<\/li>\n<li>Multiplexer applications<\/li>\n<li>Automated signal routing<\/li>\n<li>High-channel-count testing<\/li>\n<li>Functional test<\/li>\n<li>Semiconductor test<\/li>\n<\/ul>\n<h4>Integrated Analog Bus<\/h4>\n<p>\nA major feature of the PXI-2800 is its <strong>integrated analog bus<\/strong>.\n<\/p>\n<p>\nThe analog bus allows compatible SwitchBlock cards installed in the carrier to be interconnected, enabling multiple relay cards to operate as part of a larger switching matrix.\n<\/p>\n<p>\nA simplified architecture can be represented as:\n<\/p>\n<p>\n<strong>SwitchBlock Card \u2192 Integrated Analog Bus \u2192 SwitchBlock Card \u2192 DUT \/ Measurement Instrument<\/strong>\n<\/p>\n<p>\nThis interconnection capability is fundamental to building large-scale switch matrices using the PXI-2800.\n<\/p>\n<h4>More Than 2,000 Crosspoints in Four PXI Slots<\/h4>\n<p>\nBy combining multiple compatible SwitchBlock relay cards through the integrated analog bus, the PXI-2800 can support switching matrices with <strong>more than 2,000 crosspoints while occupying only four PXI slots<\/strong>.\n<\/p>\n<p>\nThis high crosspoint density makes the platform particularly attractive for automated test applications where chassis space is limited.\n<\/p>\n<h4>More Than 8,000 Crosspoints in One PXI Chassis<\/h4>\n<p>\nFor applications requiring even larger switching architectures, multiple PXI-2800 carriers can be integrated within a compatible PXI chassis.\n<\/p>\n<p>\nNI specifies that SwitchBlock architectures can scale to <strong>more than 8,000 crosspoints in a single PXI chassis<\/strong>.\n<\/p>\n<p>\nThis scalability makes SwitchBlock suitable for complex test systems containing hundreds or thousands of programmable signal paths.\n<\/p>\n<h4>Scalable Matrix Switching<\/h4>\n<p>\nThe PXI-2800 is particularly useful for applications where switching requirements may increase as a test system evolves.\n<\/p>\n<p>\nInstead of replacing the complete switching architecture, engineers can configure compatible SwitchBlock cards according to the required topology and channel count.\n<\/p>\n<p>\nThis modular approach provides flexibility for:\n<\/p>\n<ul>\n<li>Initial system development<\/li>\n<li>Channel-count expansion<\/li>\n<li>New DUT configurations<\/li>\n<li>Production test expansion<\/li>\n<li>Multi-product test platforms<\/li>\n<\/ul>\n<h4>150 V CAT I Analog Bus Rating<\/h4>\n<p>\nThe PXI-2800 analog bus supports signals up to <strong>150 V CAT I<\/strong>, subject to the electrical limits of the carrier and the installed SwitchBlock cards.\n<\/p>\n<p>\nThe carrier is intended for Measurement Category I signal applications and should not be connected directly to mains distribution circuits.\n<\/p>\n<p>\nThe electrical limits of the complete switching system are determined not only by the PXI-2800 carrier but also by the specifications of the installed SwitchBlock relay cards and system wiring.\n<\/p>\n<h4>Up to 2 A Carrier Current Capability<\/h4>\n<p>\nThe PXI-2800 carrier architecture supports up to <strong>2 A<\/strong> according to the applicable carrier specifications.\n<\/p>\n<p>\nHowever, the actual switching and carry-current capability of a completed SwitchBlock system depends on the specific relay card being used.\n<\/p>\n<p>\nFor example, different SwitchBlock cards can have different maximum voltage, current, bandwidth, relay type, and switching-power specifications.\n<\/p>\n<h4>Software-Controlled Switching<\/h4>\n<p>\nThe PXI-2800 and compatible SwitchBlock cards can be controlled programmatically as part of an automated test system.\n<\/p>\n<p>\nTest software can configure signal paths, establish matrix routes, change DUT connections, and coordinate switching operations with measurement instruments.\n<\/p>\n<p>\nThis enables complex routing operations to be performed automatically without manual cable changes.\n<\/p>\n<h3>Technical

Routing<\/td>\n<\/tr>\n<\/table>\n<h3>What Is NI SwitchBlock?<\/h3>\n<p>\nNI SwitchBlock is a modular switching architecture designed to provide very high switching density within PXI automated test systems.\n<\/p>\n<p>\nThe architecture separates the carrier from the individual switching cards:\n<\/p>\n<p>\n<strong>PXI Chassis \u2192 PXI-2800 Carrier \u2192 SwitchBlock Relay Cards \u2192 DUT \/ Instruments<\/strong>\n<\/p>\n<p>\nThe PXI-2800 provides the carrier infrastructure, while the installed SwitchBlock cards provide the actual relay switching functionality.\n<\/p>\n<p>\nThis architecture allows engineers to configure the switching system according to application-specific requirements.\n<\/p>\n<h3>PXI-2800 Is a Carrier, Not a Standalone Relay Card<\/h3>\n<p>\nAn important consideration when purchasing the PXI-2800 is that it is a <strong>SwitchBlock carrier module<\/strong>, not a complete standalone relay matrix by itself.\n<\/p>\n<p>\nCompatible SwitchBlock relay cards must be installed in the PXI-2800 to provide the required switching functionality.\n<\/p>\n<p>\nTherefore, a complete system generally requires:\n<\/p>\n<ul>\n<li>PXI-2800 carrier<\/li>\n<li>Compatible SwitchBlock relay cards<\/li>\n<li>Appropriate cables and connectors<\/li>\n<li>\u0428\u0430\u0441\u0441\u0438 PXI<\/li>\n<li>PXI controller<\/li>\n<li>NI-SWITCH software<\/li>\n<li>Measurement or stimulus instruments<\/li>\n<\/ul>\n<h3>SwitchBlock Relay Card Selection<\/h3>\n<p>\nThe actual switching specifications of a PXI-2800 system depend heavily on the SwitchBlock cards installed in the carrier.\n<\/p>\n<p>\nDifferent cards can provide different:\n<\/p>\n<ul>\n<li>Matrix topologies<\/li>\n<li>Channel counts<\/li>\n<li>Maximum voltages<\/li>\n<li>Maximum currents<\/li>\n<li>Relay technologies<\/li>\n<li>Bandwidths<\/li>\n<li>Switching speeds<\/li>\n<li>Contact resistance characteristics<\/li>\n<\/ul>\n<p>\nFor this reason, the PXI-2800 carrier and SwitchBlock cards should always be selected as a complete switching architecture rather than evaluating only the carrier specifications.\n<\/p>\n<h3>Large Matrix Switching<\/h3>\n<p>\nMatrix switching is one of the primary applications for the PXI-2800.\n<\/p>\n<p>\nA matrix switch allows multiple DUT signals and instruments to be dynamically interconnected through programmable crosspoints.\n<\/p>\n<p>\nA simplified matrix architecture can be represented as:\n<\/p>\n<p>\n<strong>DUT Signals \u2192 SwitchBlock Matrix \u2192 DMM \/ SMU \/ DAQ \/ Other Instruments<\/strong>\n<\/p>\n<p>\nTest software determines which crosspoints are closed to establish the required signal route.\n<\/p>\n<h3>What Is a Crosspoint?<\/h3>\n<p>\nA crosspoint is a programmable switching connection between two signal paths within a matrix.\n<\/p>\n<p>\nFor example, a matrix containing multiple rows and columns can selectively connect specific rows to specific columns.\n<\/p>\n<p>\nAs matrix dimensions increase, the number of possible crosspoints can become very large.\n<\/p>\n<p>\nThe ability of the PXI-2800 architecture to support thousands of crosspoints is therefore important for complex automated test systems.\n<\/p>\n<h3>High-Channel-Count Automated Testing<\/h3>\n<p>\nLarge electronic systems may contain hundreds or thousands of test points.\n<\/p>\n<p>\nUsing a dedicated measurement instrument for every test point would dramatically increase system cost, size, and complexity.\n<\/p>\n<p>\nThe PXI-2800 SwitchBlock architecture allows a smaller number of measurement instruments to be shared across many DUT signals.\n<\/p>\n<p>\n\u041d\u0430\u043f\u0440\u0438\u043c\u0435\u0440:\n<\/p>\n<p>\n<strong>Hundreds of DUT Test Points \u2192 PXI-2800 SwitchBlock \u2192 Precision Instruments \u2192 Automated Test Software<\/strong>\n<\/p>\n<p>\nThe switching matrix automatically routes each required signal to the appropriate instrument during the test sequence.\n<\/p>\n<h3>Semiconductor Test Applications<\/h3>\n<p>\nSemiconductor characterization and production test systems can require very large numbers of programmable signal connections.\n<\/p>\n<p>\nThe high crosspoint density of the PXI-2800 makes it suitable for compatible semiconductor test architectures requiring flexible routing between DUT pins and measurement instruments.\n<\/p>\n<p>\nPotential applications include:\n<\/p>\n<ul>\n<li>Device characterization<\/li>\n<li>Pin routing<\/li>\n<li>Parametric testing<\/li>\n<li>Functional testing<\/li>\n<li>Multi-site test architectures<\/li>\n<li>Automated production testing<\/li>\n<\/ul>\n<h3>Electronic Functional Testing<\/h3>\n<p>\nComplex electronic assemblies often require different DUT nodes to be connected to different instruments throughout a functional test sequence.\n<\/p>\n<p>\nA SwitchBlock system can automatically reconfigure these signal paths.\n<\/p>\n<p>\nTypical connected instruments may include:\n<\/p>\n<ul>\n<li>Digital multimeters<\/li>\n<li>Source measurement units<\/li>\n<li>Data acquisition devices<\/li>\n<li>Oscilloscopes and digitizers<\/li>\n<li>Power supplies<\/li>\n<li>Signal generators<\/li>\n<li>Other switching modules<\/li>\n<\/ul>\n<h3>Production Test Systems<\/h3>\n<p>\nProduction environments often require switching systems that can support multiple DUT types and large numbers of test points.\n<\/p>\n<p>\nThe modular architecture of the PXI-2800 allows switching configurations to be designed around the requirements of a production test fixture.\n<\/p>\n<p>\n\u0422\u0438\u043f\u0438\u0447\u043d\u044b\u0435 \u043f\u0440\u0438\u043c\u0435\u043d\u0435\u043d\u0438\u044f

testing<\/li>\n<li>Multi-point electrical measurements<\/li>\n<li>Manufacturing validation<\/li>\n<li>Automated pass\/fail testing<\/li>\n<\/ul>\n<h3>PXI-2800 with Digital Multimeters<\/h3>\n<p>\nThe PXI-2800 SwitchBlock architecture can be used to route large numbers of compatible signals to a smaller number of precision digital multimeters.\n<\/p>\n<p>\nA typical architecture is:\n<\/p>\n<p>\n<strong>DUT Test Points \u2192 SwitchBlock Matrix \u2192 PXI DMM \u2192 Test Software<\/strong>\n<\/p>\n<p>\nThe matrix selects the required signal path before each measurement, allowing the DMM to be shared across many DUT test points.\n<\/p>\n<h3>PXI-2800 with Source Measurement Units<\/h3>\n<p>\nSwitchBlock can also be used in compatible systems where multiple DUT points must share source measurement units.\n<\/p>\n<p>\nA programmable matrix can connect the required DUT node to the appropriate SMU during different stages of a test sequence.\n<\/p>\n<p>\nThis architecture can be particularly useful in semiconductor characterization and electronic component testing.\n<\/p>\n<h3>Integrated Analog Bus Architecture<\/h3>\n<p>\nThe integrated analog bus is one of the defining characteristics of the PXI-2800.\n<\/p>\n<p>\nIt provides internal signal connections that allow multiple SwitchBlock cards to operate together rather than as isolated switching cards.\n<\/p>\n<p>\nThis helps engineers construct larger matrices without requiring extensive external cabling between individual cards.\n<\/p>\n<p>\nReducing external interconnections can simplify:\n<\/p>\n<ul>\n<li>System wiring<\/li>\n<li>Matrix expansion<\/li>\n<li>Test rack construction<\/li>\n<li>\u041e\u0431\u0441\u043b\u0443\u0436\u0438\u0432\u0430\u043d\u0438\u0435<\/li>\n<li>System documentation<\/li>\n<\/ul>\n<h3>Scalable Switching Architecture<\/h3>\n<p>\nA major advantage of the PXI-2800 is scalability.\n<\/p>\n<p>\nA smaller system can begin with a PXI-2800 and the number of SwitchBlock cards required for the initial application.\n<\/p>\n<p>\nAs switching requirements increase, additional compatible cards or carrier modules can be incorporated into the system.\n<\/p>\n<p>\nThis architecture is particularly useful for test platforms that must support multiple products or future channel-count expansion.\n<\/p>\n<h3>PXI-2800 vs Conventional PXI Switch Module<\/h3>\n<table>\n<tr>\n<th>\u0424\u0443\u043d\u043a\u0446\u0438\u044f<\/th>\n<th>PXI-2800

systems can contain hundreds or thousands of possible routes, making direct relay-level programming difficult to manage.\n<\/p>\n<p>\nNI Switch Executive can be used in compatible systems to define and manage logical switching routes.\n<\/p>\n<p>\nThis can simplify development by allowing engineers to work with named signal paths instead of manually controlling every individual crosspoint.\n<\/p>\n<h3>PXI-2800 Power Considerations<\/h3>\n<p>\nThe carrier has an overall power limit that must be considered when installing and operating multiple SwitchBlock cards.\n<\/p>\n<p>\nThe total power requirement can reach approximately <strong>25 W<\/strong>, consisting of up to approximately 5 W from the 3.3 V supply and 20 W from the 5 V supply depending on the installed cards and relay configuration.\n<\/p>\n<p>\nActual relay drive limitations depend on the SwitchBlock cards installed in the carrier, so system designers should verify both individual card power requirements and overall PXI-2800 carrier limits.\n<\/p>\n<h3>Important Electrical Considerations<\/h3>\n<p>\nBefore configuring a PXI-2800 SwitchBlock system, engineers should evaluate the

Questions<\/h3>\n<h4>What is the NI PXI-2800?<\/h4>\n<p>\nThe NI PXI-2800 is a four-slot PXI carrier module designed for the NI SwitchBlock platform. It provides the carrier and interconnection architecture required to install and operate compatible SwitchBlock relay cards.\n<\/p>\n<h4>What is the part number of the PXI-2800?<\/h4>\n<p>\nThe NI ordering part number for the PXI-2800 is <strong>781420-00<\/strong>.\n<\/p>\n<h4>How many PXI slots does the PXI-2800 occupy?<\/h4>\n<p>\nThe PXI-2800 occupies <strong>four PXI slots<\/strong>.\n<\/p>\n<h4>How many SwitchBlock cards can the PXI-2800 hold?<\/h4>\n<p>\nA single PXI-2800 can hold up to <strong>six compatible SwitchBlock relay cards<\/strong>.\n<\/p>\n<h4>Does the PXI-2800 include relay cards?<\/h4>\n<p>\nThe PXI-2800 is the carrier for SwitchBlock relay cards. The required SwitchBlock cards should be selected according to the desired topology, voltage, current, bandwidth, relay type, and channel-count requirements.\n<\/p>\n<h4>How many crosspoints can the PXI-2800 support?<\/h4>\n<p>\nBy connecting compatible SwitchBlock relay cards through the integrated analog bus, a PXI-2800 system can create matrices with <strong>more than 2,000 crosspoints within four PXI slots<\/strong>.\n<\/p>\n<h4>Can multiple PXI-2800 carriers be used in one chassis?<\/h4>\n<p>\nYes. Depending on chassis capacity and system configuration, multiple SwitchBlock carriers can be used to create switching architectures with <strong>more than 8,000 crosspoints in a single PXI chassis<\/strong>.\n<\/p>\n<h4>What is the integrated analog bus?<\/h4>\n<p>\nThe integrated analog bus provides internal signal interconnections between compatible SwitchBlock cards installed in the PXI-2800. This allows multiple cards to operate together as part of a larger switching matrix.\n<\/p>\n<h4>What is the maximum voltage of the PXI-2800?<\/h4>\n<p>\nThe PXI-2800 analog bus is rated for signals up to <strong>150 V CAT I<\/strong>. The actual system limit may be lower depending on the installed SwitchBlock relay cards and complete signal path.\n<\/p>\n<h4>What is the maximum current of the PXI-2800?<\/h4>\n<p>\nThe PXI-2800 carrier supports up to <strong>2 A<\/strong>, but the actual switching and carry-current limit depends on the specific SwitchBlock card and signal path being used.\n<\/p>\n<h4>Is the PXI-2800 itself a matrix switch?<\/h4>\n<p>\nThe PXI-2800 is primarily the carrier and interconnection platform. The actual relay switching and matrix topology are provided by compatible SwitchBlock relay cards installed in the carrier.\n<\/p>\n<h4>What SwitchBlock cards can be used with the PXI-2800?<\/h4>\n<p>\nThe PXI-2800 supports compatible NI SwitchBlock cards such as members of the SWB-2810, SWB-2816, and SWB-2834 families. Compatibility and Type A\/Type B placement should be verified for the specific system configuration.\n<\/p>\n<h4>What software is used with the PXI-2800?<\/h4>\n<p>\nThe PXI-2800 SwitchBlock platform is supported by NI-SWITCH and can be integrated into compatible LabVIEW, TestStand, LabWindows\/CVI, and NI MAX workflows.\n<\/p>\n<h4>Can the PXI-2800 be simulated in NI MAX?<\/h4>\n<p>\nYes. With NI MAX and NI-SWITCH installed, engineers can create a simulated PXI-2800 SwitchBlock device and configure simulated compatible cards for software development and testing.\n<\/p>\n<h4>What is the difference between PXI-2800 and a conventional PXI switch module?<\/h4>\n<p>\nA conventional PXI switch generally contains its switching elements and topology within a single module. The PXI-2800 is a carrier architecture that accepts multiple SwitchBlock relay cards, allowing much larger and more configurable switching matrices to be created.\n<\/p>\n<h4>What applications are suitable for the PXI-2800?<\/h4>\n<p>\nTypical applications include large matrix switching, semiconductor test, high-channel-count functional testing, PCB validation, production testing, electronic characterization, multi-instrument signal routing, and other automated test systems requiring hundreds or thousands of programmable connections.\n<\/p>\n<h4>What should I check before purchasing a PXI-2800?<\/h4>\n<p>\nBefore purchasing a PXI-2800, verify the required SwitchBlock cards, matrix topology, crosspoint count, voltage and current requirements, relay technology, bandwidth, carrier power limits, Type A and Type B card compatibility, PXI chassis slot availability, cabling requirements, 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-2800 4-Slot PXI Carrier Module for SwitchBlock<\/strong> provides a scalable platform for building high-density automated switching systems.
