Simultaneous sampling maintains the timing and phase relationship among channels, unlike multiplexed acquisition systems that measure channels sequentially.<\/p>\n<p>This capability is important for applications such as:<\/p>\n<ul>\n<li>Multichannel frequency-response testing<\/li>\n<li>Phase comparison<\/li>\n<li>Structural dynamics analysis<\/li>\n<li>Acoustic arrays<\/li>\n<li>Vibration measurements<\/li>\n<li>Transient pressure testing<\/li>\n<li>Three-phase electrical measurements<\/li>\n<li>Correlated electronic signal analysis<\/li>\n<\/ul>\n<p>Each channel can independently select its input range, coupling and differential or pseudodifferential configuration.<\/p>\n<h3>24-Bit Voltage Acquisition<\/h3>\n<p>The PXIe-4481 uses 24-bit delta-sigma converters to provide low-noise measurements and high dynamic range. The module is designed to capture small signal details while also supporting input signals up to \u00b110 V peak.<\/p>\n<p>Four software-selectable voltage ranges allow the module to match different signal amplitudes:<\/p>\n<table>\n<thead>\n<tr>\n<th>Selected Range<\/th>\n<th>Full-Scale Peak Input<\/th>\n<th>Full-Scale RMS Sine Input<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>0.5 V<\/td>\n<td>\u00b10.5 V peak<\/td>\n<td>0.353 V RMS<\/td>\n<\/tr>\n<tr>\n<td>1 V<\/td>\n<td>\u00b11 V peak<\/td>\n<td>0.707 V RMS<\/td>\n<\/tr>\n<tr>\n<td>5 V<\/td>\n<td>\u00b15 V peak<\/td>\n<td>3.53 V RMS<\/td>\n<\/tr>\n<tr>\n<td>10 V<\/td>\n<td>\u00b110 V peak<\/td>\n<td>7.07 V RMS<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Selecting the smallest range that accommodates the expected signal generally provides better measurement resolution. A wider range should be selected when the input contains large transients or an uncertain peak amplitude.<\/p>\n<h3>Frequency-Domain Measurement Mode<\/h3>\n<p>Frequency-domain mode is designed for spectral measurements that require high resolution, accurate amplitude response and strong alias rejection. Sampling rates can be configured from 100 S\/s to 1.25 MS\/s per channel.<\/p>\n<p>The alias-free passband extends from DC to approximately 0.403 times the selected sample rate. At 1.25 MS\/s, the maximum alias-free bandwidth is approximately 503.75 kHz.<\/p>\n<p>The PXIe-4481 combines analog antialiasing with digital filtering to provide at least 120 dBc alias rejection under the specified conditions. This helps prevent high-frequency signals from appearing incorrectly at lower frequencies in the measured spectrum.<\/p>\n<p>Frequency-domain mode is suitable for:<\/p>\n<ul>\n<li>FFT spectrum analysis<\/li>\n<li>Harmonic and distortion measurements<\/li>\n<li>Frequency-response analysis<\/li>\n<li>Noise measurements<\/li>\n<li>Order tracking<\/li>\n<li>Dynamic signal analysis<\/li>\n<li>Audio and ultrasonic testing<\/li>\n<li>Vibration spectrum analysis<\/li>\n<\/ul>\n<h3>20 MS\/s Time-Domain Mode<\/h3>\n<p>Time-domain mode provides sampling rates up to 20 MS\/s per channel for capturing rapid signal changes. This mode prioritizes time resolution and low-latency transient acquisition rather than the full digital filtering available in frequency-domain mode.<\/p>\n<p>Typical time-domain applications include:<\/p>\n<ul>\n<li>Blast and shock event capture<\/li>\n<li>High-speed pressure transients<\/li>\n<li>Impact testing<\/li>\n<li>Pyrotechnic event measurement<\/li>\n<li>Rapid switching transients<\/li>\n<li>Short-duration acoustic pulses<\/li>\n<li>Electronic waveform analysis<\/li>\n<li>High-speed structural response testing<\/li>\n<\/ul>\n<p>Select frequency-domain mode when spectral accuracy and antialias filtering are the primary requirements. Select time-domain mode when the application must capture a fast event with maximum temporal resolution.<\/p>\n<h3>Dynamic Range and Noise Performance<\/h3>\n<p>The PXIe-4481 provides a maximum dynamic range of up to 115 dB under the specified input-range, sample-rate and bandwidth conditions. Dynamic range varies with the selected voltage range and sample rate.<\/p>\n<table>\n<thead>\n<tr>\n<th>Voltage Range<\/th>\n<th>Dynamic Range at 51.2 kS\/s<\/th>\n<th>Dynamic Range at 1.25 MS\/s<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>10 V<\/td>\n<td>113 dB<\/td>\n<td>98 dB<\/td>\n<\/tr>\n<tr>\n<td>5 V<\/td>\n<td>115 dB<\/td>\n<td>100 dB<\/td>\n<\/tr>\n<tr>\n<td>1 V<\/td>\n<td>112 dB<\/td>\n<td>98 dB<\/td>\n<\/tr>\n<tr>\n<td>0.5 V<\/td>\n<td>107 dB<\/td>\n<td>94 dB<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Higher sample rates increase the measured noise bandwidth and can reduce the resulting full-band dynamic range. Select a sample rate and measurement bandwidth appropriate for the signal frequencies that must be analyzed.<\/p>\n<h3>AC and DC Input Coupling<\/h3>\n<p>Each channel can be independently configured for AC or DC coupling. DC coupling preserves the complete signal, including its static component, and is suitable for direct-voltage, low-frequency and transient measurements.<\/p>\n<p>AC coupling blocks the DC component and is useful when the measurement focuses on dynamic signal content. The AC-coupled input has a \u22123 dB cutoff frequency of approximately 0.49 Hz and a \u22120.1 dB cutoff near 3.2 Hz.<\/p>\n<p>Use DC coupling when signal content approaching 0 Hz must be measured. Use AC coupling when a DC offset would otherwise reduce the available input range for the dynamic portion of the signal.<\/p>\n<h3>Differential and Pseudodifferential Inputs<\/h3>\n<p>The PXIe-4481 supports differential and pseudodifferential voltage configurations. Differential mode measures the voltage difference between the positive and negative input terminals and provides improved rejection of common-mode noise.<\/p>\n<p>Pseudodifferential mode connects the negative input to chassis ground through a 50 \u03a9 resistance. It can be useful for signals referenced to system ground, but grounding and common-mode voltage should be checked carefully to prevent unwanted current paths.<\/p>\n<p>The PXIe-4481 does not provide isolated input channels. The source voltage, common-mode level and grounding arrangement must remain within the module\u2019s specified limits.<\/p>\n<h3>Adjustable Digital Filter Delay<\/h3>\n<p>The module\u2019s digital filtering introduces a predictable delay in frequency-domain acquisition. This delay is compensated to zero by default and can be adjusted through software when an application requires a particular timing relationship.<\/p>\n<p>Adjustable delay is valuable when synchronizing the PXIe-4481 with other measurement modules, compensating for sensor delays or aligning channels within a larger data acquisition system.<\/p>\n<h3>Typical PXIe-4481 Applications<\/h3>\n<ul>\n<li>High-bandwidth voltage measurement<\/li>\n<li>Dynamic signal acquisition<\/li>\n<li>Frequency-domain analysis<\/li>\n<li>Time-domain transient capture<\/li>\n<li>Blast and pressure event testing<\/li>\n<li>Audio and ultrasonic measurements<\/li>\n<li>Structural vibration testing<\/li>\n<li>Automotive NVH analysis<\/li>\n<li>Aerospace acoustic and vibration testing<\/li>\n<li>Electronic signal-chain validation<\/li>\n<li>Power electronics waveform acquisition<\/li>\n<li>\u041c\u043e\u043d\u0438\u0442\u043e\u0440\u0438\u043d\u0433 \u0441\u043e\u0441\u0442\u043e\u044f\u043d\u0438\u044f \u043e\u0431\u043e\u0440\u0443\u0434\u043e\u0432\u0430\u043d\u0438\u044f<\/li>\n<li>Research and laboratory automation<\/li>\n<li>High-speed synchronized data acquisition<\/li>\n<\/ul>\n<h3>Synchronization and Triggering<\/h3>\n<p>The PXIe-4481 supports PXI Express timing and triggering resources for coordinating acquisition with other PXI instruments. The front-panel SMB programmable function interface can be used for supported external timing and trigger signals.<\/p>\n<p>Multiple modules can be synchronized when more than six channels are required. A common timebase should be used when maintaining intermodule phase relationships is important.<\/p>\n<p>For high-accuracy multichannel measurements, allow the modules to complete the recommended warm-up period and use consistent ranges, coupling settings and timing configurations.<\/p>\n<h3>Software and Driver Support<\/h3>\n<p>The PXIe-4481 uses the NI-DAQmx driver for input configuration, timing, triggering, filtering and data acquisition. It can be programmed through supported versions of LabVIEW, LabWindows\/CVI, C\/C++, .NET and Python.<\/p>\n<p>FlexLogger can be used for interactive measurement configuration, data logging, triggering and alarms. The LabVIEW Sound and Vibration Toolkit provides additional frequency, octave, order, transient and vibration analysis functions.<\/p>\n<p>NI DIAdem supports offline data processing, visualization and automated report generation. Confirm software, driver and operating-system compatibility before installing the module in an existing PXI system.<\/p>\n<h3>PXIe-4481 Connectivity<\/h3>\n<p>The six analog input channels are accessed through a front-panel InfiniBand connector. An appropriate breakout cable, terminal block or application-specific interface is required to connect individual signals.<\/p>\n<p>The module also includes an SMB programmable function interface for supported triggering and timing. Cables and connection accessories may need to be ordered separately.<\/p>\n<h3>PXIe-4481 Chassis Compatibility<\/h3>\n<p>The PXIe-4481 is a PXI Express module and requires a compatible PXI Express peripheral or hybrid slot. It cannot be installed in a traditional PXI-only peripheral slot.<\/p>\n<p>Before purchasing, verify the chassis slot type, controller, NI-DAQmx compatibility, cooling and available PCI Express bandwidth. High-speed acquisition across six channels can produce substantial data throughput, especially in time-domain mode.<\/p>\n<h3>PXIe-4481 Troubleshooting<\/h3>\n<h4>The Input Waveform Is Clipped<\/h4>\n<p>Select a wider input range and confirm that the signal does not exceed the configured full-scale value. Consider transient peaks in addition to the normal steady-state amplitude.<\/p>\n<h4>The Measurement Contains Excessive Noise<\/h4>\n<p>Select the smallest range that does not clip the signal and avoid using a sample rate much higher than required. Use differential wiring, shielded cables and proper grounding.<\/p>\n<h4>Low-Frequency Signals Are Attenuated<\/h4>\n<p>Check whether AC coupling is enabled. Select DC coupling when the measurement must include static or very low-frequency signal content.<\/p>\n<h4>Unexpected Frequencies Appear in the Spectrum<\/h4>\n<p>Verify that frequency-domain mode is selected and that the signal of interest remains within the alias-free bandwidth. Increase the sample rate or reduce unwanted out-of-band interference if necessary.<\/p>\n<h4>The Module Cannot Sustain 20 MS\/s Streaming<\/h4>\n<p>Check the PXI Express backplane, controller, system memory and storage write speed. Six channels operating at 20 MS\/s generate a large amount of data.<\/p>\n<h4>Phase Measurements Differ Across Modules<\/h4>\n<p>Synchronize all modules to a common timebase and configure equivalent sampling and filtering settings. Account for intermodule clock skew when calculating phase accuracy.<\/p>\n<h4>The Module Is Not Detected<\/h4>\n<p>Confirm that the PXIe-4481 is installed in a compatible PXI Express or hybrid slot. Check the PXI controller, NI-DAQmx installation and device recognition in NI Measurement &amp; Automation Explorer.<\/p>\n<h3>PXIe-4481 Compared with Similar Analog Input Modules<\/h3>\n<table>\n<thead>\n<tr>\n<th>\u041c\u043e\u0434\u0435\u043b\u044c<\/th>\n<th>Input Channels<\/th>\n<th>Maximum Standard Sample Rate<\/th>\n<th>Maximum Time-Domain Rate<\/th>\n<th>Primary Capability<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>PXIe-4464<\/td>\n<td>4<\/td>\n<td>204.8 kS\/s<\/td>\n<td>Not applicable<\/td>\n<td>Sound and vibration input with IEPE conditioning<\/td>\n<\/tr>\n<tr>\n<td>PXIe-4468<\/td>\n<td>2<\/td>\n<td>250 kS\/s<\/td>\n<td>Not applicable<\/td>\n<td>Two inputs, two outputs and IEPE conditioning<\/td>\n<\/tr>\n<tr>\n<td>PXIe-4480<\/td>\n<td>6<\/td>\n<td>1,25 \u041c\u0421\u043c\/\u0441<\/td>\n<td>20 MS\/s<\/td>\n<td>Voltage, charge, IEPE, voltage excitation and TEDS<\/td>\n<\/tr>\n<tr>\n<td>PXIe-4481<\/td>\n<td>6<\/td>\n<td>1,25 \u041c\u0421\u043c\/\u0441<\/td>\n<td>20 MS\/s<\/td>\n<td>High-bandwidth voltage acquisition<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The PXIe-4481 and PXIe-4480 provide similar voltage acquisition, frequency-domain filtering and time-domain sampling capabilities.
