Independent 8\u00d71 Multiplexer Banks<\/h4>\n<p>\nThe PXIe-2525 provides <strong>two independent 8\u00d71 multiplexer banks<\/strong>.\n<\/p>\n<p>\nEach bank can select one of multiple input channels and connect the selected signal to a common measurement path.\n<\/p>\n<p>\nThe dual-bank architecture provides additional flexibility for applications requiring two independently controlled signal groups.\n<\/p>\n<h4>PXI Express Switching Platform<\/h4>\n<p>\nThe PXIe-2525 is designed for the <strong>PXI Express platform<\/strong>, allowing programmable signal switching to be integrated directly into a modular automated test system.\n<\/p>\n<p>\nThe module can operate alongside other PXI and PXI Express instruments in a compatible chassis, allowing switching, measurement, generation, and control functions to be combined within one test platform.\n<\/p>\n<h4>Multiplexer Signal Routing<\/h4>\n<p>\nA multiplexer allows multiple DUT signals to share a smaller number of measurement instruments.\n<\/p>\n<p>\nA typical PXIe-2525 measurement architecture can be represented as:\n<\/p>\n<p>\n<strong>DUT Signals \u2192 PXIe-2525 \u2192 DMM \/ DAQ \/ Measurement Instrument \u2192 Test Software<\/strong>\n<\/p>\n<p>\nThe test software selects the required signal path, performs the measurement, and then switches to the next channel automatically.\n<\/p>\n<h4>150 V CAT I Signal Capability<\/h4>\n<p>\nThe PXIe-2525 is designed for signal-switching applications with ratings appropriate for <strong>CAT I measurement environments<\/strong>.\n<\/p>\n<p>\nThis makes the module suitable for routing compatible electronic signals in automated test and measurement systems.\n<\/p>\n<p>\nUsers should always verify the exact voltage, current, power, and category limits for the selected topology and terminal configuration before connecting a DUT.\n<\/p>\n<h4>Electromechanical Relay Switching<\/h4>\n<p>\nThe PXIe-2525 uses <strong>electromechanical relay switching<\/strong>, making it suitable for applications where signal integrity, low leakage, and flexible measurement routing are important.\n<\/p>\n<p>\nCompared with semiconductor switching technologies, electromechanical relays can provide advantages for applications requiring:\n<\/p>\n<ul>\n<li>Low leakage<\/li>\n<li>High isolation<\/li>\n<li>Low contact resistance<\/li>\n<li>DC and low-frequency signal routing<\/li>\n<li>Precision measurements<\/li>\n<\/ul>\n<h4>Software-Controlled Signal Routing<\/h4>\n<p>\nThe PXIe-2525 can be controlled programmatically as part of an automated test sequence.\n<\/p>\n<p>\nSoftware can automatically:\n<\/p>\n<ul>\n<li>Open and close switch routes<\/li>\n<li>Select measurement channels<\/li>\n<li>Change DUT connections<\/li>\n<li>Coordinate switching with measurements<\/li>\n<li>Execute repetitive test sequences<\/li>\n<li>Automate multi-channel measurements<\/li>\n<\/ul>\n<h4>High-Channel-Count Measurement Expansion<\/h4>\n<p>\nMultiplexer switching allows a limited number of precision instruments to measure a larger number of DUT signals.\n<\/p>\n<p>\nInstead of dedicating a measurement instrument to every signal, the PXIe-2525 can sequentially route multiple signals to a shared instrument.\n<\/p>\n<p>\nThis can reduce:\n<\/p>\n<ul>\n<li>Instrument count<\/li>\n<li>System cost<\/li>\n<li>Rack space<\/li>\n<li>System complexity<\/li>\n<li>Calibration requirements<\/li>\n<\/ul>\n<h3>Technical

common measurement paths.\n<\/p>\n<p>\nFor example, an electronic assembly may contain multiple voltage measurement points but the automated test system may contain only one precision digital multimeter.\n<\/p>\n<p>\nThe multiplexer allows the DMM to measure these signals sequentially:\n<\/p>\n<p>\n<strong>Channel 1 \u2192 PXIe-2525 \u2192 DMM \u2192 Measurement<\/strong><br \/>\n<strong>Channel 2 \u2192 PXIe-2525 \u2192 DMM \u2192 Measurement<\/strong><br \/>\n<strong>Channel 3 \u2192 PXIe-2525 \u2192 DMM \u2192 Measurement<\/strong><br \/>\n<strong>&#8230; \u2192 Continue Automated Test Sequence<\/strong>\n<\/p>\n<p>\nThis architecture is widely used in automated test systems because it allows precision measurement instruments to be shared across multiple DUT channels.\n<\/p>\n<h3>Dual-Bank Multiplexer Architecture<\/h3>\n<p>\nA key characteristic of the PXIe-2525 is its <strong>two-bank switching architecture<\/strong>.\n<\/p>\n<p>\nInstead of providing only one multiplexer group, the module provides two independently controlled 8\u00d71 banks.\n<\/p>\n<p>\nThis architecture can be useful when a test system needs to independently route two groups of signals.\n<\/p>\n<p>\n\u041d\u0430\u043f\u0440\u0438\u043c\u0435\u0440:\n<\/p>\n<p>\n<strong>Signal Group A \u2192 Bank 1 \u2192 Measurement Path A<\/strong><br \/>\n<strong>Signal Group B \u2192 Bank 2 \u2192 Measurement Path B<\/strong>\n<\/p>\n<p>\nThe exact wiring architecture should be configured according to the application&#8217;s signal and measurement requirements.\n<\/p>\n<h3>PXIe-2525 with a Digital Multimeter<\/h3>\n<p>\nOne of the most common applications for the PXIe-2525 is signal routing to a digital multimeter.\n<\/p>\n<p>\nA PXI DMM can provide precision measurement capability while the PXIe-2525 determines which DUT signal is connected to the instrument.\n<\/p>\n<p>\nA typical architecture is:\n<\/p>\n<p>\n<strong>Multiple DUT Test Points \u2192 PXIe-2525 \u2192 PXI DMM \u2192 Test Software<\/strong>\n<\/p>\n<p>\nDepending on the DMM and system wiring, this architecture can support automated measurements such as:\n<\/p>\n<ul>\n<li>DC voltage<\/li>\n<li>AC voltage<\/li>\n<li>Resistance<\/li>\n<li>Continuity<\/li>\n<li>Other compatible electrical measurements<\/li>\n<\/ul>\n<h3>PXIe-2525 with Data Acquisition Systems<\/h3>\n<p>\nThe PXIe-2525 can also be used as a signal-routing layer for compatible data acquisition systems.\n<\/p>\n<p>\nA switching module can increase the number of signals accessible to a limited number of DAQ measurement channels.\n<\/p>\n<p>\n\u041d\u0430\u043f\u0440\u0438\u043c\u0435\u0440:\n<\/p>\n<p>\n<strong>Sensors \/ DUT Signals \u2192 PXIe-2525 \u2192 DAQ Module \u2192 PXI Controller<\/strong>\n<\/p>\n<p>\nThe system sequentially selects the required signal and performs the measurement according to the programmed test sequence.\n<\/p>\n<h3>Automated Functional Testing<\/h3>\n<p>\nFunctional test systems frequently require different DUT signals to be connected to measurement equipment at different stages of a test.\n<\/p>\n<p>\nThe PXIe-2525 can automate this routing process.\n<\/p>\n<ol>\n<li>Select the required DUT channel.<\/li>\n<li>Close the appropriate PXIe-2525 route.<\/li>\n<li>Perform the measurement.<\/li>\n<li>Open the route.<\/li>\n<li>Select the next channel.<\/li>\n<li>Repeat the measurement sequence.<\/li>\n<li>Store and evaluate the test results.<\/li>\n<\/ol>\n<p>\nAutomated switching reduces manual cable changes and improves measurement repeatability.\n<\/p>\n<h3>Electronic Device Validation<\/h3>\n<p>\nDuring design verification and validation, engineers often need to measure multiple signals across a circuit board or electronic subsystem.\n<\/p>\n<p>\nThe PXIe-2525 can dynamically route these test points to compatible measurement instruments.\n<\/p>\n<p>\n\u0422\u0438\u043f\u0438\u0447\u043d\u044b\u0435

The PXIe-2525 provides two independently controlled 8\u00d71 banks.\n<\/p>\n<h4>Is the PXIe-2525 a PXI or PXI Express module?<\/h4>\n<p>\nThe PXIe-2525 is a <strong>PXI Express<\/strong> switch module designed for installation in a compatible PXI Express chassis.\n<\/p>\n<h4>Can the PXIe-2525 be used with a digital multimeter?<\/h4>\n<p>\nYes. One of its primary applications is routing multiple compatible DUT signals to a shared digital multimeter for automated sequential measurements.\n<\/p>\n<h4>Can the PXIe-2525 be used with a DAQ system?<\/h4>\n<p>\nYes. It can be used to route multiple compatible signals to data acquisition hardware, allowing measurement channels to be shared across multiple test points.\n<\/p>\n<h4>Can the PXIe-2525 be used for resistance measurements?<\/h4>\n<p>\nThe module can be used as part of compatible resistance measurement systems when connected to an appropriate DMM or measurement instrument. Wiring configuration, contact resistance, lead resistance, and the required measurement accuracy should be considered.\n<\/p>\n<h4>What is the advantage of the two-bank architecture?<\/h4>\n<p>\nThe two independent banks allow two groups of signals to be routed separately, providing greater flexibility than a single 8\u00d71 multiplexer.\n<\/p>\n<h4>Does the PXIe-2525 use FET switches?<\/h4>\n<p>\nNo. The PXIe-2525 uses electromechanical relays. If an application requires very fast repetitive switching and extremely high switching-cycle capability, a FET-based switch such as the PXI-2533 may be more appropriate.\n<\/p>\n<h4>What does 150 V CAT I mean?<\/h4>\n<p>\nCAT I refers to measurements on circuits that are not directly connected to the building mains distribution system. The actual signal voltage, current, switching power, and measurement-category limits specified for the PXIe-2525 must always be observed.\n<\/p>\n<h4>What software is used with the PXIe-2525?<\/h4>\n<p>\nThe PXIe-2525 can be controlled using NI-SWITCH and integrated into automated test applications developed with LabVIEW, TestStand, LabWindows\/CVI, and other compatible software environments.\n<\/p>\n<h4>Can the PXIe-2525 be used for automated production testing?<\/h4>\n<p>\nYes. Programmable signal routing makes the PXIe-2525 suitable for automated functional test, PCB testing, electronic assembly validation, and production test systems.\n<\/p>\n<h4>What is the difference between PXIe-2525 and PXI-2533?<\/h4>\n<p>\nThe PXIe-2525 is an electromechanical relay multiplexer with two independent 8\u00d71 banks, while the PXI-2533 is a much higher-density FET-based switching module. The PXIe-2525 is better suited to applications where relay-based signal characteristics are important, while the PXI-2533 is advantageous for high-density and frequent high-speed switching.\n<\/p>\n<h4>What applications are suitable for the PXIe-2525?<\/h4>\n<p>\nTypical applications include DMM signal routing, DAQ channel expansion, automated functional testing, PCB validation, electronic device testing, sensor measurements, production test, and laboratory automation.\n<\/p>\n<h4>What should I check before purchasing a PXIe-2525?<\/h4>\n<p>\nBefore purchasing a PXIe-2525, verify the required multiplexer topology, channel count, signal voltage, switching current, switching power, measurement category, contact resistance, bandwidth, relay lifetime, required terminal block or cable, PXI Express 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 PXIe-2525 PXI Express Multiplexer Switch Module<\/strong> provides two independent 8\u00d71 multiplexer banks for software-controlled signal routing in automated test systems.
