When combined with a compatible PXI FPGA Module or Controller for FlexRIO, it creates a flexible high-speed digitizer platform for custom measurement and signal-processing systems.\n<\/p>\n<p>\nWith

Instruments NI-5734<\/strong> is a FlexRIO digitizer adapter module rather than a standalone digitizer.\n<\/p>\n<p>\nIt is designed to operate with a compatible <strong>FlexRIO FPGA module or controller<\/strong>.\n<\/p>\n<p>\nA typical system architecture is:\n<\/p>\n<p>\n<strong>Analog Signals \u2192 NI-5734 \u2192 FlexRIO FPGA Module \u2192 PXI\/PXIe System \u2192 Host Software<\/strong>\n<\/p>\n<p>\nThe NI-5734 performs high-speed analog acquisition while the FPGA provides customizable real-time processing, triggering, data reduction, protocol implementation, and streaming functionality.\n<\/p>\n<h3>Key Features<\/h3>\n<h4>4 Analog Input Channels<\/h4>\n<p>\nThe NI-5734 provides <strong>four analog input channels<\/strong> for acquiring multiple high-speed analog signals.\n<\/p>\n<p>\nThe four-channel architecture is useful for applications requiring synchronized measurement of several related signals.\n<\/p>\n<p>\n\u0422\u0438\u043f\u0438\u0447\u043d\u044b\u0435 \u043f\u0440\u0438\u043c\u0435\u043d\u0435\u043d\u0438\u044f \u0432\u043a\u043b\u044e\u0447\u0430\u044e\u0442:\n<\/p>\n<ul>\n<li>Multi-channel waveform acquisition<\/li>\n<li>Electronic validation<\/li>\n<li>Transient signal analysis<\/li>\n<li>Research instrumentation<\/li>\n<li>High-speed sensor measurement<\/li>\n<li>Custom digitizer systems<\/li>\n<li>Signal monitoring<\/li>\n<li>Automated test<\/li>\n<\/ul>\n<h4>120 MS\/s per Channel<\/h4>\n<p>\nThe NI-5734 provides sampling rates up to <strong>120 MS\/s per channel<\/strong>.\n<\/p>\n<p>\nAll four analog input channels can be sampled simultaneously, providing an aggregate acquisition capability of up to:\n<\/p>\n<p>\n<strong>4 Channels \u00d7 120 MS\/s = 480 MS\/s Aggregate<\/strong>\n<\/p>\n<p>\nThis high-speed simultaneous architecture preserves timing relationships between channels and makes the NI-5734 suitable for multi-channel waveform and transient measurements.\n<\/p>\n<h4>Simultaneous Sampling<\/h4>\n<p>\nThe NI-5734 provides <strong>simultaneous sampling across all four analog input channels<\/strong>.\n<\/p>\n<p>\nUnlike multiplexed data acquisition devices that measure channels sequentially, simultaneous sampling captures each channel at the same sampling instant.\n<\/p>\n<p>\nThis is important for:\n<\/p>\n<ul>\n<li>Phase comparison<\/li>\n<li>Time-domain analysis<\/li>\n<li>Transient measurements<\/li>\n<li>\u041c\u043d\u043e\u0433\u043e\u043a\u0430\u043d\u0430\u043b\u044c\u043d\u0430\u044f

uses <strong>16-bit analog-to-digital conversion<\/strong>.\n<\/p>\n<p>\nThe combination of 16-bit resolution and 120 MS\/s sampling provides a balance between high acquisition speed and measurement resolution for demanding high-speed instrumentation applications.\n<\/p>\n<h4>117 MHz Analog Input Bandwidth<\/h4>\n<p>\nThe NI-5734 provides up to approximately <strong>117 MHz analog input bandwidth<\/strong>.\n<\/p>\n<p>\nThe wide analog bandwidth allows the digitizer to acquire high-frequency signal content while maintaining high-speed digital sampling.\n<\/p>\n<h4>\u00b11 V Analog Input Range<\/h4>\n<p>\nThe NI-5734 supports an analog input voltage range of approximately <strong>-1 V to +1 V<\/strong>.\n<\/p>\n<p>\nSignal amplitude should be verified before connection to ensure that the input remains within the supported electrical limits.\n<\/p>\n<h4>AC and DC Coupling<\/h4>\n<p>\nThe NI-5734 supports selectable <strong>AC and DC input coupling<\/strong>.\n<\/p>\n<p>\nDC coupling allows both DC and AC components of a signal to be measured, while AC coupling can be useful when the DC component should be removed before acquisition.\n<\/p>\n<h4>Selectable Hardware Filters<\/h4>\n<p>\nThe NI-5734 includes selectable analog hardware filters that can be configured according to the measurement requirements.\n<\/p>\n<p>\nAvailable filter paths include:\n<\/p>\n<ul>\n<li><strong>Elliptic Filter<\/strong><\/li>\n<li><strong>Bessel Filter<\/strong><\/li>\n<li><strong>Bypass<\/strong><\/li>\n<\/ul>\n<p>\nThe appropriate filter can be selected according to the application&#8217;s frequency-domain, time-domain, and signal-integrity requirements.\n<\/p>\n<h4>Elliptic Filter<\/h4>\n<p>\nThe selectable <strong>elliptic hardware filter<\/strong> provides a sharper frequency-domain transition and can be useful when strong out-of-band attenuation is required.\n<\/p>\n<h4>Bessel Filter<\/h4>\n<p>\nThe selectable <strong>Bessel hardware filter<\/strong> is useful for applications where preserving waveform shape and time-domain characteristics is important.\n<\/p>\n<h4>Filter Bypass<\/h4>\n<p>\nThe bypass configuration provides the widest available analog signal path when the application&#8217;s bandwidth requirements take priority over additional hardware filtering.\n<\/p>\n<h4>Real-Time FPGA Processing<\/h4>\n<p>\nOne of the primary advantages of the NI-5734 is its integration with the <strong>FlexRIO FPGA architecture<\/strong>.\n<\/p>\n<p>\nInstead of simply transferring every acquired sample directly to the host computer, the FPGA can process data in real time.\n<\/p>\n<p>\nPotential FPGA operations include:\n<\/p>\n<ul>\n<li>Digital filtering<\/li>\n<li>Custom triggering<\/li>\n<li>Threshold

The resulting digital data is then transferred directly to the FPGA for deterministic processing.\n<\/p>\n<h3>NI-5734 Is Not a Standalone Digitizer<\/h3>\n<p>\nAn important consideration when purchasing the NI-5734 is that it is a <strong>FlexRIO adapter module<\/strong>.\n<\/p>\n<p>\nIt does not function as a complete standalone PXI digitizer by itself.\n<\/p>\n<p>\nA complete acquisition

combined with an appropriate FlexRIO FPGA module, PXIe chassis, controller, and storage architecture, acquired data can be processed and transferred at high rates for continuous or event-based acquisition.\n<\/p>\n<h3>Custom Triggering<\/h3>\n<p>\nBecause acquired samples are available to the FPGA, engineers can implement application-specific trigger logic instead of relying only on conventional fixed hardware trigger modes.\n<\/p>\n<p>\nExamples include:\n<\/p>\n<ul>\n<li>Threshold triggering<\/li>\n<li>Window triggering<\/li>\n<li>Multi-channel trigger conditions<\/li>\n<li>Pattern detection<\/li>\n<li>Event qualification<\/li>\n<li>Custom timing sequences<\/li>\n<\/ul>\n<h3>Custom Digital Signal Processing<\/h3>\n<p>\nThe FPGA can perform
