Key FeaturesHigh Resolution, High Accuracy Analog MeasurementsNI Multifunction I/O Devices have analog signal paths that have been meticulously designed, tested, andcalibrated to ensure the highest possible accuracy is achieved across all input channels. Because of thisthorough design-and-test philosophy, NI is able to provide thoroughly documented accuracyspecifications to allow a complete understanding of device performance under a range of possibleoperating conditions. The specifications documentation for each device provides a section dedicated tounderstanding the calculation of AI absolute accuracy, alongside a wealth of other performance details.Advanced Timing TechnologyAll multifunction data acquisition hardware requires onboard timing circuitry to control analog, digital, andcounter I/O lines. Much of the Multifunction I/O Device family features the NI-STC3 chipset to provide upto four enhanced counters, a 100 MHz timebase, and additional options for I/O timing and triggering.Figure 1. Modern NI DAQ devices feature NI-STC3 timing and synchronization technology – a USB Multifunction I/ODevice is shown here as an example.100 MHz TimebaseThe onboard timebase of any data acquisition device acts as the internal heartbeat that drives all digitalcircuitry. Everything from sample clocks to trigger lines uses the timebase as an onboard reference togenerate clock frequencies and latch digital edges. Modern devices use a 100 MHz timebase for allanalog and digital timing, which is up to five times faster than their predecessors. This means thatsampling frequencies are up to five times more accurate, and analog triggers can respond within 10 ns ofa trigger condition being met.Independent Timing Engines for Analog and Digital I/OAdvanced timing and triggering functionality on data acquisition devices has often relied on onboardcounters and complex signal routing to achieve specialized hardware-timed performance. NI’smultifunction I/O technology offers completely independent sample clocks and triggers for each differentgroup of I/O on a multifunction device. Retriggerable acquisitions, for example, involve waiting for atrigger condition to be met, taking a finite number of samples, and then immediately rearming the triggerfor the next acquisition. Using driver software function calls to rearm the trigger risks missing the nexttrigger due to software latency; therefore, the best possible performance requires a hardware-timedapproach. In the past, counters were the only way to implement hardware-timed retriggering, and socounters would be used to generate a retriggerable pulse train, which was then internally routed to act asPage 7 ni.com Multifunction I/O

the analog input sample clock. Devices with advanced timing capabilities can perform this type of actionnatively, which greatly simplifies the hardware programming and measurement configuration process.Self-Calibration and Two-Year Guaranteed SpecificationsSelf-calibration provides the ability to characterize nonlinearity, gain, and offset errors in Multifunction I/ODevices. These changes are caused by deviations in the operating environment as well as manufacturingvariations in the integrated circuitry that may have shifted since the last external calibration. Supporteddevices use an integrated self-calibration algorithm called NI-MCal to characterize and save thecorrection polynomials to an onboard EEPROM, and does so in a matter of seconds. This allowssubsequent measurements to be scaled automatically by the device driver software before being returnedto the user through application software. NI-MCal has the unique ability to return calibrated data fromevery channel in a scan, even if they are at different input ranges. This means a device can easily loadand apply channel-specific correction functions even while scanning at maximum device rates withoutimpacting performance.By eliminating the limitations of hardware components traditionally used for device error correction andusing the power and speed of software and PC processing, NI-MCal raises the bar for measurementaccuracy by redefining device self-calibration. Most Multifunction I/O Device models have a two-yearexternal calibration cycle thanks to the self-calibration precision circuitry that minimizes the maintenanceburden of deployed systems, while also maintaining tight measurement tolerances.
