It plays a crucial role in engineering, scientific research, and industrial settings, enabling real-time monitoring and control of parameters like temperature, pressure, and voltage. DAQ is essential for quality control, process optimization, and troubleshooting.</p> <h2>What is a DAQ System?</h2> <p>A DAQ (Data Acquisition) system is a comprehensive setup for measuring and collecting data from various sensors or transducers, crucial in fields like scientific research, industrial automation, and more. It typically includes sensors or transducers<strong></strong>that convert physical or electrical signals into measurable quantities, signal conditioning circuits for amplifying, filtering, or digitizing signals for enhanced quality and accuracy and a data acquisition device that samples and digitizes signals, preparing them for further analysis.</p> <p><picture><source media="all and (min-width: 767px)" data-srcset="/-/media/marketing-docs/d/daq-data-acquisition-primer-introduction-multi-channel-measurement-systems/fig-1.png?w=954"><source media="all and (min-width: 544px)" data-srcset="/-/media/marketing-docs/d/daq-data-acquisition-primer-introduction-multi-channel-measurement-systems/fig-1.png?w=767"><source media="all and (min-width: 0px)" data-srcset="/-/media/marketing-docs/d/daq-data-acquisition-primer-introduction-multi-channel-measurement-systems/fig-1.png?w=544"><img alt="Components of a Data Acquisition System Block diagram" src="/patternlab/images/transparent-pixel.png" width="954" height="429" data-src="/-/media/marketing-docs/d/daq-data-acquisition-primer-introduction-multi-channel-measurement-systems/fig-1.png?h=429&w=954" class="lazy"></picture></p> <h2>Find a DAQ System for Your Application</h2> <p>As a leader in test and measurement technology, <a href="/en/products/keithley">Keithley</a> provides DAQ systems that are not just high-performing but highly adaptable, meeting the needs of diverse industries from environmental monitoring to <a href="/en/solutions/industry/automotive-test-solutions">automotive testing</a>.</p> <div class="row" itemscope itemtype="http://schema.org/OfferCatalog"> <meta itemprop="numberOfItems" content="5" /> <link itemprop="url" href="https://www.tek.com/en/products/keithley/data-acquisition-daq-systems" /> <meta itemprop="name" content="Data Acquisition Systems (DAQ)" /> <div class="col-sm-12"> <div class="multi-line"> <div class="col-sm-6 col-lg-4 product-card" itemprop=itemListElement itemscope itemtype=http://schema.org/OfferCatalog> <link itemprop="url" href="https://www.tek.com/en/products/keithley/digital-multimeter/keithley-daq6510" /> <meta itemprop="brand" content="Tektronix" /> <span itemprop="itemListElement" itemscope="" itemtype="http://schema.org/Offer"> <span itemprop="itemOffered" itemscope="" itemtype="http://schema.org/Product"> <meta itemprop="name" content="Keithley DAQ6510 6½-Digit Data Acquisition and Logging Multimeter System" /> <meta itemprop="description" content="DAQ6510 Data Acquisition and Logging, Multimeter System" /> <meta itemprop="URL" content="/en/products/keithley/digital-multimeter/keithley-daq6510" /> <meta itemprop="Image" content="https://www.tek.com/-/media/images/product-series/daq6500/daq6510-front_7700_7703cardstop_5in.jpg" /> <meta itemprop="brand" content="Tektronix" /> <meta itemprop="sku" content="DAQ6510" /> <span itemprop="offers" itemscope="" itemtype="http://schema.org/Offer"> <meta itemprop="URL" content="/en/products/keithley/digital-multimeter/keithley-daq6510" /> <meta itemprop="priceCurrency" content="SGD" /> <meta itemprop="sku" content="DAQ6510" /> <meta itemprop="price" content="3740" /> <link itemprop="availability" href="http://schema.org/InStock"> </span> </span> </span> <a href="/en/products/keithley/digital-multimeter/keithley-daq6510"> <div class="product-card__image"> <picture><source media="all and (min-width: 544px)" data-srcset="/-/media/images/product-series/daq6500/daq6510-front_7700_7703cardstop_5in.jpg?w=640"><source media="all and (min-width: 0px)" data-srcset="/-/media/images/product-series/daq6500/daq6510-front_7700_7703cardstop_5in.jpg?w=544"><img src="/patternlab/images/transparent-pixel.png" alt="" width="640" height="560" itemprop="image" data-src="/-/media/images/product-series/daq6500/daq6510-front_7700_7703cardstop_5in.jpg?h=560&iar=0&w=640" class="lazy"></picture> </div> <div class="product-card__text"> <h3> Keithley DAQ6510 6½-Digit Data Acquisition and Logging Multimeter System </h3> <div> <ul> <li>Two-slot, 80-channel capacity</li> <li>6½-digit DMM for precision measurement</li> <li>Touchscreen display to simplify setup, monitoring, and data analysis</li> </ul> </div> </div> </a> </div> <div class="col-sm-6 col-lg-4 product-card" itemprop=itemListElement itemscope itemtype=http://schema.org/OfferCatalog> <link itemprop="url" href="https://www.tek.com/en/products/keithley/data-acquisition-daq-systems/2700-multimeter-data-acquisition-switch-system" /> <meta itemprop="brand" content="Tektronix" /> <span itemprop="itemListElement" itemscope="" itemtype="http://schema.org/Offer"> <span itemprop="itemOffered" itemscope="" itemtype="http://schema.org/Product"> <meta itemprop="name" content="Keithley 2700 Multimeter/Data Acquisition/Switch Systems" /> <meta itemprop="description" content="Discover Keithley 2700 Multimeter/Data Acquisition/Switch Systems, offering precision measurement, switching, and control.
