matrix crosspoints<\/strong>.\n<\/p>\n<p>\nA crosspoint represents a potential electrical connection between a row and a column in the matrix.\n<\/p>\n<p>\n\u041d\u0430\u043f\u0440\u0438\u043c\u0435\u0440:\n<\/p>\n<p>\n<strong>4 Rows \u00d7 32 Columns = 128 Crosspoints<\/strong>\n<\/p>\n<p>\nor:\n<\/p>\n<p>\n<strong>8 Rows \u00d7 16 Columns = 128 Crosspoints<\/strong>\n<\/p>\n<p>\nThis high-density architecture allows a large number of DUT signals to share a smaller number of measurement instruments.\n<\/p>\n<h4>2-Wire Matrix Architecture<\/h4>\n<p>\nThe PXI-2529 is a <strong>2-wire matrix switch<\/strong>.\n<\/p>\n<p>\nEach matrix connection switches two conductors together, making the module particularly suitable for differential and two-wire measurement architectures.\n<\/p>\n<p>\nTypical two-wire applications include:\n<\/p>\n<ul>\n<li>Precision voltage measurement<\/li>\n<li>Resistance measurement<\/li>\n<li>Current measurement architectures<\/li>\n<li>Source Measure Unit routing<\/li>\n<li>DMM routing<\/li>\n<li>Two-wire DUT interfaces<\/li>\n<\/ul>\n<h4>4\u00d732 Matrix Configuration<\/h4>\n<p>\nThe PXI-2529 can be configured as a <strong>4\u00d732 2-wire matrix<\/strong> using an appropriate terminal block.\n<\/p>\n<p>\nThis topology provides four instrument-side rows and 32 DUT-side columns.\n<\/p>\n<p>\nA typical architecture is:\n<\/p>\n<p>\n<strong>4 Measurement \/ Source Paths \u2194 32 DUT Signal Paths<\/strong>\n<\/p>\n<p>\nThis configuration is particularly useful when a relatively small number of instruments must be routed to a large number of DUT connections.\n<\/p>\n<h4>8\u00d716 Matrix Configuration<\/h4>\n<p>\nThe PXI-2529 can also be configured as an <strong>8\u00d716 2-wire matrix<\/strong>.\n<\/p>\n<p>\nThis provides additional row connections while reducing the number of available columns.\n<\/p>\n<p>\nA typical architecture is:\n<\/p>\n<p>\n<strong>8 Measurement \/ Source Paths \u2194 16 DUT Signal Paths<\/strong>\n<\/p>\n<p>\nThe 8\u00d716 topology can be useful when a test system contains more instruments or source channels that need access to the DUT.\n<\/p>\n<h4>Electromechanical Relay Technology<\/h4>\n<p>\nThe PXI-2529 uses <strong>\u044d\u043b\u0435\u043a\u0442\u0440\u043e\u043c\u0435\u0445\u0430\u043d\u0438\u0447\u0435\u0441\u043a\u0438\u0435 \u0440\u0435\u043b\u0435<\/strong> for signal switching.\n<\/p>\n<p>\nElectromechanical relays provide several advantages for general-purpose automated test:\n<\/p>\n<ul>\n<li>Low contact resistance<\/li>\n<li>Low leakage<\/li>\n<li>Good isolation<\/li>\n<li>Ability to route DC signals<\/li>\n<li>Ability to route AC signals within specification<\/li>\n<li>Low thermal offset<\/li>\n<li>Support for relatively high switching voltage and current<\/li>\n<\/ul>\n<h4>150 V Maximum Switching Voltage<\/h4>\n<p>\nThe PXI-2529 supports a maximum switching voltage of up to <strong>150 VDC<\/strong> within its specified operating limits.\n<\/p>\n<p>\nThis allows the module to route substantially higher voltages than many low-voltage semiconductor-based digital switching solutions.\n<\/p>\n<p>\nThe 150 V rating is a critical electrical and safety limit and should not be exceeded.\n<\/p>\n<h4>1 A Maximum DC Switching Current<\/h4>\n<p>\nThe PXI-2529 supports a maximum DC switching current of <strong>1 A<\/strong>.\n<\/p>\n<p>\nThe actual allowable switching conditions depend on voltage, current, power, topology, terminal block, environmental conditions, and other specifications.\n<\/p>\n<p>\nUsers should therefore evaluate the complete NI switching specifications rather than considering voltage and current ratings independently.\n<\/p>\n<h4>120 Cycles\/s Scan Rate<\/h4>\n<p>\nNI specifies a scan rate of up to <strong>120 cycles per second<\/strong> for the PXI-2529.\n<\/p>\n<p>\nAutomated scanning allows the test system to sequentially connect instruments to multiple DUT points without manual rewiring.\n<\/p>\n<p>\nA typical sequence is:\n<\/p>\n<p>\n<strong>Connect DUT 1 \u2192 Measure \u2192 Disconnect \u2192 Connect DUT 2 \u2192 Measure \u2192 Repeat<\/strong>\n<\/p>\n<h4>Low Thermal Offset<\/h4>\n<p>\nThe electromechanical relay architecture of the PXI-2529 is designed to provide low thermal offset for accurate low-level measurements.\n<\/p>\n<p>\nThis is particularly important when the matrix is used with precision measurement instruments such as:\n<\/p>\n<ul>\n<li>Digital multimeters<\/li>\n<li>Source Measure Units<\/li>\n<li>Precision voltage measurement instruments<\/li>\n<li>Low-level data acquisition systems<\/li>\n<\/ul>\n<h4>Onboard Relay Counting<\/h4>\n<p>\nThe PXI-2529 provides <strong>onboard relay counting<\/strong> to help monitor relay usage.\n<\/p>\n<p>\nBecause electromechanical relays have a finite mechanical life, relay-count information can be valuable for preventive maintenance and test-system reliability management.\n<\/p>\n<p>\nMaintenance software can use relay-count information to identify heavily used signal paths before relay wear begins affecting production testing.\n<\/p>\n<h4>Hardware Triggering<\/h4>\n<p>\nThe PXI-2529 supports hardware-triggered switching for deterministic operation in automated test systems.\n<\/p>\n<p>\nHardware triggering can coordinate switch operations with:\n<\/p>\n<ul>\n<li>\u0426\u0438\u0444\u0440\u043e\u0432\u044b\u0435 \u043c\u0443\u043b\u044c\u0442\u0438\u043c\u0435\u0442\u0440\u044b PXI<\/li>\n<li>Source Measure Units<\/li>\n<li>Data acquisition modules<\/li>\n<li>Digitizers<\/li>\n<li>Power supplies<\/li>\n<li>Other PXI instrumentation<\/li>\n<\/ul>\n<p>\nThis can improve test throughput compared with test sequences that depend entirely on software commands.\n<\/p>\n<h4>PXI Hybrid Compatibility<\/h4>\n<p>\nThe PXI-2529 uses a <strong>PXI Hybrid<\/strong> bus connector.\n<\/p>\n<p>\nThis allows the module to be integrated into compatible PXI chassis and automated test systems alongside other PXI instrumentation.\n<\/p>\n<h3>Technical

matrix.\n<\/p>\n<p>\nSoftware determines which row-to-column crosspoints are closed.\n<\/p>\n<p>\nFor example, in a 4\u00d732 configuration:\n<\/p>\n<p>\n<strong>Instrument Row 0 \u2192 DUT Column 5<\/strong><br \/>\n<strong>Instrument Row 1 \u2192 DUT Column 12<\/strong><br \/>\n<strong>Instrument Row 2 \u2192 DUT Column 20<\/strong><br \/>\n<strong>Instrument Row 3 \u2192 DUT Column 28<\/strong>\n<\/p>\n<p>\nThe matrix can then be reconfigured automatically for the next measurement sequence.\n<\/p>\n<h3>What Is a Matrix Switch?<\/h3>\n<p>\nA matrix switch provides programmable connections between multiple rows and multiple columns.\n<\/p>\n<p>\nA simplified matrix can be represented as:\n<\/p>\n<p>\n<strong>Rows = Measurement Instruments \/ Sources<\/strong><br \/>\n<strong>Columns = DUT Test Points<\/strong>\n<\/p>\n<p>\nThe intersections between rows and columns are called crosspoints.\n<\/p>\n<p>\nClosing a crosspoint connects the corresponding row to the corresponding column.\n<\/p>\n<h3>Matrix Switch vs Multiplexer<\/h3>\n<table>\n<tr>\n<th>\u0424\u0443\u043d\u043a\u0446\u0438\u044f<\/th>\n<th>Matrix

application for the PXI-2529 is routing multiple DUT test points to a PXI digital multimeter.\n<\/p>\n<p>\nA typical architecture is:\n<\/p>\n<p>\n<strong>Multiple DUT Test Points \u2192 PXI-2529 \u2192 PXI Digital Multimeter<\/strong>\n<\/p>\n<p>\nThe switch automatically selects the required DUT signal while the DMM performs the measurement.\n<\/p>\n<p>\nThis architecture can dramatically increase the effective channel count of a precision DMM without requiring one measurement instrument for every test point.\n<\/p>\n<h3>PXI-2529 for Source Measure Unit Routing<\/h3>\n<p>\nThe PXI-2529 can also route compatible voltage and current signals between Source Measure Units and multiple DUT connections.\n<\/p>\n<p>\nA simplified architecture is:\n<\/p>\n<p>\n<strong>PXI SMU \u2192 PXI-2529 \u2192 Multiple DUTs<\/strong>\n<\/p>\n<p>\nThis allows a smaller number of SMUs to be shared across multiple test points when simultaneous connections are not required.\n<\/p>\n<p>\nAll applied voltages, currents, power levels, and isolation requirements must remain within the PXI-2529 specifications.\n<\/p>\n<h3>Multi-DUT Testing<\/h3>\n<p>\nThe high-density matrix architecture makes the PXI-2529 useful for multi-DUT automated testing.\n<\/p>\n<p>\n\u041d\u0430\u043f\u0440\u0438\u043c\u0435\u0440:\n<\/p>\n<p>\n<strong>DMM \/ SMU \/ Power Supply \u2192 PXI-2529 \u2192 DUT 1 \/ DUT 2 \/ DUT 3 \/ DUT 4<\/strong>\n<\/p>\n<p>\nTest software can dynamically reconfigure the matrix so that instruments are shared between DUTs.\n<\/p>\n<p>\nThis approach can reduce:\n<\/p>\n<ul>\n<li>Instrument count<\/li>\n<li>PXI chassis slot requirements<\/li>\n<li>System cost<\/li>\n<li>External cabling complexity<\/li>\n<li>Manual connection changes<\/li>\n<\/ul>\n<h3>Semiconductor Test Applications<\/h3>\n<p>\nSemiconductor characterization and production test systems often require multiple precision instruments to connect to many DUT pins.\n<\/p>\n<p>\nThe PXI-2529 can provide programmable routing between compatible DUT connections and instruments such as:\n<\/p>\n<ul>\n<li>Source Measure Units<\/li>\n<li>Digital multimeters<\/li>\n<li>Power supplies<\/li>\n<li>Data acquisition modules<\/li>\n<li>Electronic loads<\/li>\n<\/ul>\n<p>\nA matrix architecture allows the same instruments to be reused across multiple DUT connections.\n<\/p>\n<h3>Electronic Functional Testing<\/h3>\n<p>\nThe PXI-2529 can be incorporated into functional test systems for electronic assemblies, modules, and printed circuit boards.\n<\/p>\n<p>\nTypical measurements may include:\n<\/p>\n<ul>\n<li>DC voltage<\/li>\n<li>Resistance<\/li>\n<li>Continuity<\/li>\n<li>Current<\/li>\n<li>Power rail verification<\/li>\n<li>Component validation<\/li>\n<\/ul>\n<h3>Low-Level Measurement Applications<\/h3>\n<p>\nSwitches can introduce unwanted thermoelectric voltages when different conductive materials and temperature gradients are present.\n<\/p>\n<p>\nThe low thermal offset characteristics of the PXI-2529 electromechanical relays make the module suitable for precision low-voltage measurements when the complete measurement system is designed appropriately.\n<\/p>\n<p>\n\u0422\u0438\u043f\u0438\u0447\u043d\u044b\u0435 \u043f\u0440\u0438\u043c\u0435\u043d\u0435\u043d\u0438\u044f

characterization<\/li>\n<li>Semiconductor characterization<\/li>\n<li>Precision automated test<\/li>\n<\/ul>\n<h3>High-Voltage Signal Routing<\/h3>\n<p>\nThe PXI-2529 can switch signals up to <strong>150 V<\/strong> within its specified operating conditions.\n<\/p>\n<p>\nThis makes it suitable for automated systems requiring signal levels beyond typical low-voltage DAQ applications.\n<\/p>\n<p>\nHowever, <strong>150 V is a critical maximum rating<\/strong>. The module should not be used to route signals exceeding its specified voltage limit.\n<\/p>\n<h3>Relay Life and Relay Counting<\/h3>\n<p>\nElectromechanical relays have a finite operating life that depends strongly on switching conditions.\n<\/p>\n<p>\nFactors affecting relay life include:\n<\/p>\n<ul>\n<li>Switching voltage<\/li>\n<li>Switching current<\/li>\n<li>Load type<\/li>\n<li>Switching frequency<\/li>\n<li>Electrical arcing<\/li>\n<li>Environmental conditions<\/li>\n<\/ul>\n<p>\nThe PXI-2529 onboard relay-counting capability can help maintenance teams monitor relay usage and plan preventative replacement.\n<\/p>\n<h3>PXI-2529 Terminal Blocks<\/h3>\n<p>\nThe PXI-2529 uses front-mount terminal blocks to define its matrix topology and external signal connections.\n<\/p>\n<p>\nNI provides several terminal block options for the NI 2529 family.\n<\/p>\n<h4>TB-2634<\/h4>\n<p>\n\u0417\u0435\u043c\u043b\u044f <strong>NI TB-2634, part number 778840-01<\/strong>, configures the
