provides <strong>8 differential analog input channels<\/strong>.\n<\/p>\n<p>\nDifferential measurement helps reject common-mode interference and is particularly useful when measuring signals that are not referenced to the same ground potential.\n<\/p>\n<p>\nEight channels can be used to measure several voltage points in parallel, such as:\n<\/p>\n<ul>\n<li>Multiple power rails<\/li>\n<li>Battery cells or battery sections<\/li>\n<li>Converter input and output voltages<\/li>\n<li>Motor drive signals<\/li>\n<li>Industrial power circuits<\/li>\n<li>Multiple DUT voltage nodes<\/li>\n<\/ul>\n<h4>16-Bit Analog-to-Digital Conversion<\/h4>\n<p>\nEach PXIe-4310 channel uses a <strong>16-bit analog-to-digital converter<\/strong>.\n<\/p>\n<p>\nA 16-bit ADC provides 65,536 theoretical quantization levels across the selected measurement range.\n<\/p>\n<table>\n<tr>\n<th>\u0420\u0430\u0437\u0440\u0435\u0448\u0435\u043d\u0438\u0435<\/th>\n<th>Theoretical Quantization

Bit<\/strong><\/td>\n<td><strong>65,536<\/strong><\/td>\n<\/tr>\n<\/table>\n<p>\nActual measurement accuracy depends on the selected input range, terminal block, calibration, environmental conditions, noise, and other analog specifications.\n<\/p>\n<h4>400 kS\/s Per Channel<\/h4>\n<p>\nThe PXIe-4310 supports a maximum sampling rate of <strong>400 kS\/s per channel<\/strong>.\n<\/p>\n<p>\nBecause each channel has its own ADC, this sampling capability is available simultaneously across the analog input channels.\n<\/p>\n<p>\nThis makes the module suitable for capturing dynamic voltage signals and transient electrical behavior.\n<\/p>\n<h4>Simultaneous Sampling<\/h4>\n<p>\nA major advantage of the PXIe-4310 is its <strong>simultaneous sampling architecture<\/strong>.\n<\/p>\n<p>\nInstead of multiplexing multiple signals through one ADC, each analog input channel has a dedicated converter.\n<\/p>\n<p>\nThis means voltage measurements from different channels correspond to the same point in time, which is important for:\n<\/p>\n<ul>\n<li>Phase measurements<\/li>\n<li>Power analysis<\/li>\n<li>Input\/output comparison<\/li>\n<li>Multi-rail transient testing<\/li>\n<li>Converter efficiency measurements<\/li>\n<li>Dynamic system characterization<\/li>\n<\/ul>\n<h4>Channel-to-Channel Isolation<\/h4>\n<p>\nThe PXIe-4310 provides <strong>channel-to-channel isolation<\/strong>, allowing individual analog inputs to operate at different electrical potentials.\n<\/p>\n<p>\nIsolation is particularly important when measurements are taken from different sections of high-voltage systems.\n<\/p>\n<p>\nIt can help:\n<\/p>\n<ul>\n<li>Break ground loops<\/li>\n<li>Reduce common-mode interference<\/li>\n<li>Separate measurement channels<\/li>\n<li>Improve safety in appropriate high-voltage systems<\/li>\n<li>Measure floating signals<\/li>\n<\/ul>\n<h4>Up to 600 V Channel-to-Channel Isolation<\/h4>\n<p>\nNI specifies the PXIe-4310 family with up to <strong>600 V channel-to-channel isolation<\/strong> when used within the applicable system and terminal-block limits.\n<\/p>\n<p>\nThe complete measurement configuration, including terminal block, wiring, installation, insulation, and measurement category requirements, must be verified before working with high-voltage signals.\n<\/p>\n<h4>Two TB-4310 Terminal Block Options<\/h4>\n<p>\nThe voltage range available from the PXIe-4310 depends on the selected <strong>TB-4310 front-mount terminal block<\/strong>.\n<\/p>\n<table>\n<tr>\n<th>Terminal Block<\/th>\n<th>Part Number<\/th>\n<th>Measurement

PXIe-4310 module for either precision low-voltage measurement or isolated high-voltage acquisition.\n<\/p>\n<h4>\u00b110 V Measurement with TB-4310 (10 V)<\/h4>\n<p>\nWhen the PXIe-4310 is paired with the <strong>TB-4310 (10 V)<\/strong>, the system provides four programmable input ranges:\n<\/p>\n<ul>\n<li>\u00b11 V<\/li>\n<li>\u00b12 V<\/li>\n<li>\u00b15 V<\/li>\n<li>\u00b110 V<\/li>\n<\/ul>\n<p>\nThis configuration is appropriate for lower-voltage sensors, electronic circuits, power rails, and other signals where a \u00b110 V maximum measurement range is sufficient.\n<\/p>\n<h4>\u00b1600 V Measurement with TB-4310 (600 V)<\/h4>\n<p>\nWhen paired with the <strong>TB-4310 (600 V)<\/strong>, the PXIe-4310 supports high-voltage measurement ranges of:\n<\/p>\n<ul>\n<li>\u00b160 V<\/li>\n<li>\u00b1120 V<\/li>\n<li>\u00b1300 V<\/li>\n<li>\u00b1600 V<\/li>\n<\/ul>\n<p>\nThe 600 V terminal block contains attenuation circuitry that extends the underlying PXIe-4310 measurement range for high-voltage applications.\n<\/p>\n<h4>Up to Four Input Ranges Concurrently<\/h4>\n<p>\nThe PXIe-4310 architecture allows up to <strong>four different input ranges<\/strong> to be used concurrently with the appropriate terminal block and software configuration.\n<\/p>\n<p>\nThis is useful when different channels in the same test system measure signals with significantly different amplitudes.\n<\/p>\n<p>\n\u041d\u0430\u043f\u0440\u0438\u043c\u0435\u0440:\n<\/p>\n<p>\n<strong>Channel 0 \u2192 \u00b1600 V<\/strong><br \/>\n<strong>Channel 1 \u2192 \u00b1300 V<\/strong><br \/>\n<strong>Channel 2 \u2192 \u00b1120 V<\/strong><br \/>\n<strong>Channel 3 \u2192 \u00b160 V<\/strong>\n<\/p>\n<p>\nThis flexibility helps maximize measurement resolution without requiring all channels to use the largest available range.\n<\/p>\n<h4>Per-Channel Filtering<\/h4>\n<p>\nThe PXIe-4310 provides programmable filtering for analog input channels.\n<\/p>\n<p>\nNI specifies discrete low-pass filter options including:\n<\/p>\n<ul>\n<li>10 kHz<\/li>\n<li>100 kHz<\/li>\n<\/ul>\n<p>\nPer-channel filtering can help reduce unwanted high-frequency noise before the signal is digitized or processed.\n<\/p>\n<h4>Independent ADC Per Channel<\/h4>\n<p>\nEach PXIe-4310 analog input has an independent ADC.\n<\/p>\n<p>\nThis architecture eliminates the channel-to-channel timing skew associated with conventional multiplexed acquisition systems.\n<\/p>\n<p>\nIt is particularly valuable when several signals must be compared precisely in time.\n<\/p>\n<h4>Multiple Triggering Configurations<\/h4>\n<p>\nThe PXIe-4310 supports flexible triggering and clocking configurations for automated acquisition.\n<\/p>\n<p>\nTwo PFI lines are available for external triggering and clocking functions.\n<\/p>\n<p>\nTriggering can be used to synchronize acquisition with:\n<\/p>\n<ul>\n<li>DUT startup<\/li>\n<li>Power switching events<\/li>\n<li>External test equipment<\/li>\n<li>Automated production sequences<\/li>\n<li>Other PXI instrumentation<\/li>\n<\/ul>\n<h4>NI-DAQmx Support<\/h4>\n<p>\nThe PXIe-4310 is supported by <strong>\u041d\u0418-DAQmx<\/strong>.\n<\/p>\n<p>\nNI-DAQmx provides driver support for configuring acquisition channels, voltage ranges, sampling, triggering, filtering, and data

Measurements<\/td>\n<\/tr>\n<\/table>\n<h3>What Is an Isolated Analog Input Module?<\/h3>\n<p>\nAn isolated analog input module electrically separates measurement channels from one another and from other parts of the measurement system.\n<\/p>\n<p>\nThis differs from many conventional multifunction DAQ modules where several channels share a common measurement reference.\n<\/p>\n<p>\nA simplified isolated architecture is:\n<\/p>\n<p>\n<strong>Signal 1 \u2192 Isolated Channel 1<\/strong><br \/>\n<strong>Signal 2 \u2192 Isolated Channel 2<\/strong><br \/>\n<strong>Signal 3 \u2192 Isolated Channel 3<\/strong><br \/>\n<strong>Signal 4 \u2192 Isolated Channel 4<\/strong>\n<\/p>\n<p>\nEach signal can operate at a different common-mode potential within the specified isolation limits.\n<\/p>\n<h3>Why Channel-to-Channel Isolation Matters<\/h3>\n<p>\nChannel-to-channel isolation is particularly valuable when measuring several electrical nodes that cannot safely share the same reference.\n<\/p>\n<p>\nTypical examples include:\n<\/p>\n<ul>\n<li>Power converter input and output<\/li>\n<li>Series-connected battery sections<\/li>\n<li>Motor drive phases<\/li>\n<li>Floating power rails<\/li>\n<li>Industrial power circuits<\/li>\n<li>Power supply outputs<\/li>\n<\/ul>\n<p>\nWithout appropriate isolation, connecting these signals to a common-ground measurement system can create ground loops, measurement errors, or unsafe electrical paths.\n<\/p>\n<h3>PXIe-4310 for High-Voltage Measurement<\/h3>\n<p>\nHigh-voltage measurement is one of the key applications of the PXIe-4310 when combined with the <strong>TB-4310 (600 V)<\/strong>.\n<\/p>\n<p>\nAvailable high-voltage ranges include:\n<\/p>\n<ul>\n<li>\u00b160 V<\/li>\n<li>\u00b1120 V<\/li>\n<li>\u00b1300 V<\/li>\n<li>\u00b1600 V<\/li>\n<\/ul>\n<p>\nThis enables direct acquisition of many power electronics and industrial voltage signals without requiring an external voltage divider in suitable applications.\n<\/p>\n<h3>Power Electronics Testing<\/h3>\n<p>\nThe PXIe-4310 is particularly well suited for automated power electronics measurement systems.\n<\/p>\n<p>\nTypical DUTs may include:\n<\/p>\n<ul>\n<li>DC\/DC converters<\/li>\n<li>AC\/DC converters<\/li>\n<li>DC\/AC inverters<\/li>\n<li>Power supplies<\/li>\n<li>Motor drives<\/li>\n<li>Battery chargers<\/li>\n<li>Power distribution units<\/li>\n<li>Industrial power modules<\/li>\n<\/ul>\n<h3>DC\/DC Converter Testing<\/h3>\n<p>\nA DC\/DC converter test system may need to acquire both input and output voltages simultaneously.\n<\/p>\n<p>\nA simplified architecture is:\n<\/p>\n<p>\n<strong>Channel 0 \u2192 Converter Input Voltage<\/strong><br \/>\n<strong>Channel 1 \u2192 Converter Output Voltage<\/strong>\n<\/p>\n<p>\nBecause the PXIe-4310 provides independent ADCs, both waveforms can be captured simultaneously.\n<\/p>\n<p>\nAdditional channels can monitor auxiliary rails, control voltages, or other circuit nodes.\n<\/p>\n<h3>Inverter Testing<\/h3>\n<p>\nThe PXIe-4310 can be incorporated into inverter and power-conversion test platforms requiring isolated voltage measurements.\n<\/p>\n<p>\nTypical measurements may include:\n<\/p>\n<ul>\n<li>DC bus voltage<\/li>\n<li>Converter output voltage<\/li>\n<li>Phase-related voltages<\/li>\n<li>Control supply voltages<\/li>\n<li>Transient voltage behavior<\/li>\n<\/ul>\n<p>\nThe required measurement category, isolation, probe architecture, and system safety limits must be verified for the specific inverter application.\n<\/p>\n<h3>\u0422\u0435\u0441\u0442\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u0435 \u0431\u0430\u0442\u0430\u0440\u0435\u0438<\/h3>\n<p>\nBattery and energy storage systems frequently contain several measurement points operating at different electrical potentials.\n<\/p>\n<p>\nThe PXIe-4310 can provide isolated simultaneous voltage acquisition for compatible battery test systems.\n<\/p>\n<p>\nApplications may include:\n<\/p>\n<ul>\n<li>Battery pack voltage monitoring<\/li>\n<li>Battery module testing<\/li>\n<li>Charge and discharge validation<\/li>\n<li>Transient voltage measurement<\/li>\n<li>Energy storage system characterization<\/li>\n<\/ul>\n<h3>Electric Vehicle Testing<\/h3>\n<p>\nElectric vehicles contain numerous low-voltage and high-voltage electrical subsystems.\n<\/p>\n<p>\nThe PXIe-4310 can be incorporated into compatible EV validation systems for measuring isolated voltage signals associated with:\n<\/p>\n<ul>\n<li>Battery systems<\/li>\n<li>Power converters<\/li>\n<li>Charging systems<\/li>\n<li>Power distribution<\/li>\n<li>Electronic control systems<\/li>\n<li>Low-voltage auxiliary circuits<\/li>\n<\/ul>\n<h3>Power Supply Validation<\/h3>\n<p>\nPower supply testing commonly requires simultaneous measurements of several output rails.\n<\/p>\n<p>\nThe PXIe-4310 can capture these signals in parallel.\n<\/p>\n<p>\n\u041d\u0430\u043f\u0440\u0438\u043c\u0435\u0440:\n<\/p>\n<p>\n<strong>Channel 0 \u2192 Input Voltage<\/strong><br \/>\n<strong>Channel 1 \u2192 Output Rail 1<\/strong><br \/>\n<strong>Channel 2 \u2192 Output Rail 2<\/strong><br \/>\n<strong>Channel 3 \u2192 Output Rail 3<\/strong>\n<\/p>\n<p>\nThis enables engineers to analyze startup, shutdown, regulation, sequencing, and transient behavior.\n<\/p>\n<h3>Power Sequencing Measurements<\/h3>\n<p>\nModern electronic devices often require several voltage rails to rise and fall in a defined sequence.\n<\/p>\n<p>\nBecause the PXIe-4310 samples channels simultaneously, it can capture the timing relationship between multiple supply rails.\n<\/p>\n<p>\nMeasurements may include:\n<\/p>\n<ul>\n<li>Rail startup timing<\/li>\n<li>Power-good sequencing<\/li>\n<li>Voltage settling<\/li>\n<li>Shutdown timing<\/li>\n<li>Overshoot<\/li>\n<li>Undershoot<\/li>\n<\/ul>\n<h3>Transient Voltage Measurement<\/h3>\n<p>\nWith a maximum sample rate of 400 kS\/s per channel, the PXIe-4310 can capture many transient voltage events that would be missed by slower monitoring instruments.\n<\/p>\n<p>\nExamples include:\n<\/p>\n<ul>\n<li>Power-up transients<\/li>\n<li>Load changes<\/li>\n<li>Switching events<\/li>\n<li>Fault conditions<\/li>\n<li>Supply

channels, multiple PXIe-4310 modules can be installed in compatible PXI Express systems.\n<\/p>\n<p>\nPXI timing and synchronization capabilities can also support larger multi-module or multi-chassis acquisition architectures.\n<\/p>\n<p>\nThis makes the PXIe-4310 suitable for scalable high-channel-count voltage measurement systems.\n<\/p>\n<h3>Measurement Range Selection<\/h3>\n<p>\nChoosing the smallest suitable input range generally helps maximize measurement resolution.\n<\/p>\n<p>\nFor example, a signal expected to remain within \u00b15 V should normally use an appropriate lower input range rather than automatically using a \u00b110 V or \u00b1600 V range.\n<\/p>\n<p>\nSimilarly, high-voltage measurements should use the smallest appropriate range supported by the TB-4310 (600 V).\n<\/p>\n<p>\nCorrect range selection can improve effective measurement performance while maintaining sufficient headroom for the expected signal.\n<\/p>\n<h3>Filtering Considerations<\/h3>\n<p>\nThe selectable 10 kHz and 100 kHz low-pass filtering options allow users to balance bandwidth and noise performance.\n<\/p>\n<p>\nA lower cutoff can be useful when:\n<\/p>\n<ul>\n<li>The signal changes relatively slowly<\/li>\n<li>High-frequency noise is unwanted<\/li>\n<li>Measurement stability is more important than bandwidth<\/li>\n<\/ul>\n<p>\nA higher filter setting may be more appropriate when faster signal dynamics must be retained.\n<\/p>\n<h3>High-Voltage Safety Considerations<\/h3>\n<p>\nHigh-voltage measurement requires careful system-level design.\n<\/p>\n<p>\nBefore using the PXIe-4310 with the TB-4310 (600 V), verify:\n<\/p>\n<ul>\n<li>Maximum measurement voltage<\/li>\n<li>Channel-to-channel voltage<\/li>\n<li>Channel-to-ground voltage<\/li>\n<li>Measurement category requirements<\/li>\n<li>Terminal block ratings<\/li>\n<li>Wire insulation ratings<\/li>\n<li>Clearance and creepage requirements<\/li>\n<li>PXI system grounding<\/li>\n<li>Safety enclosure requirements<\/li>\n<li>Applicable electrical safety procedures<\/li>\n<\/ul>\n<p>\nThe \u00b1600 V measurement range should not be interpreted as permission to connect any arbitrary 600 V source without verifying the complete installation and applicable NI safety specifications.\n<\/p>\n<h3>PXIe-4310 Selection Considerations<\/h3>\n<p>\nBefore purchasing the
