Software-selectable input ranges help improve measurement resolution when working with signals smaller than the full \u00b110 V range.<\/p>\n<p>The multiplexed analog input architecture is suitable for applications that require multiple measurement channels without simultaneous sampling. The aggregate sampling rate is shared among the channels included in a hardware-timed acquisition.<\/p>\n<h3>Analog Output and Control<\/h3>\n<p>Two analog output channels can generate programmable voltage signals for device stimulus, setpoint control and closed-loop testing. Hardware-timed waveform generation allows the output operation to be coordinated with analog acquisition and digital events.<\/p>\n<h3>Digital I\/O and Counter Functions<\/h3>\n<p>The 24 bidirectional digital lines support static and hardware-timed digital operations. Four 32-bit counters can perform encoder measurements, frequency and period measurements, event counting, pulse-width measurements and pulse-train or PWM generation.<\/p>\n<h3>PXIe-6321 Applications<\/h3>\n<ul>\n<li>Automated functional testing<\/li>\n<li>Sensor and voltage measurement<\/li>\n<li>Laboratory data acquisition<\/li>\n<li>Motor and actuator control<\/li>\n<li>Encoder and frequency measurement<\/li>\n<li>Hardware-in-the-loop test systems<\/li>\n<li>Production-line test equipment<\/li>\n<li>Research and educational laboratories<\/li>\n<\/ul>\n<h3>PXIe-6321 Accessories<\/h3>\n<p>The module can be connected to compatible 68-pin shielded cables and terminal blocks such as the SHC68-68-EPM cable and SCB-68A connector block. Accessory selection should be based on shielding, terminal style and the required analog and digital signals.<\/p>\n<h3>PXIe-6321 Troubleshooting<\/h3>\n<h4>The module is not detected<\/h4>\n<p>Verify that the module is fully installed in a compatible PXI Express slot. Check chassis power, controller communication and the installed NI-DAQmx version.<\/p>\n<h4>Analog measurements are noisy<\/h4>\n<p>Confirm the terminal configuration, grounding and input range. Use shielded cabling, separate analog wiring from switching loads and avoid leaving unused measurement inputs floating.<\/p>\n<h4>The sample rate is lower than expected<\/h4>\n<p>The 250 kS\/s specification is an aggregate rate. When multiple analog input channels are scanned, the available rate is divided across the active channels.<\/p>\n<h3>Frequently Asked Questions<\/h3>\n<h4>Does the PXIe-6321 support differential inputs?<\/h4>\n<p>Yes. It supports up to eight differential or 16 single-ended analog input channels.<\/p>\n<h4>Which driver controls the PXIe-6321?<\/h4>\n<p>The module is programmed through NI-DAQmx and can be used with LabVIEW and supported C, C++ and .NET environments.<\/p>\n<h3>Request a Quote for PXIe-6321<\/h3>\n<p>Contact us for current availability, configuration assistance and project pricing for the <strong>PXIe-6321 Multifunction I\/O Module<\/strong>.
