High-Energy Physics<\/td>\n<\/tr>\n<\/table>\n<h3>Simultaneous Sampling Explained<\/h3>\n<p>\nThe most important characteristic of the PXI-6122 is its <strong>simultaneous-sampling architecture<\/strong>.\n<\/p>\n<p>\nIn a multiplexed DAQ module, several analog input channels share one ADC. The module switches from one input channel to another before each conversion, creating a small time offset between samples.\n<\/p>\n<p>\nThe PXI-6122 is designed differently. Its four analog input channels can be digitized simultaneously, allowing the system to maintain accurate time correlation between multiple waveforms.\n<\/p>\n<p>\nThis architecture is especially valuable for transient measurements, phase comparisons, ultrasonic signals, sonar systems, and other applications where timing relationships between channels must be preserved.\n<\/p>\n<h3>Analog Input Performance<\/h3>\n<p>\nThe PXI-6122 provides four differential analog inputs with 16-bit resolution and sampling rates up to 500 kS\/s on each channel.\n<\/p>\n<p>\nBecause all four channels can operate simultaneously at the maximum sampling rate, the module can acquire an aggregate of up to approximately 2 million analog samples per second.\n<\/p>\n<p>\nThis differs fundamentally from multiplexed DAQ modules where the specified maximum sampling rate may be shared across multiple enabled channels.\n<\/p>\n<h3>PXI Timing and Triggering<\/h3>\n<p>\nThe PXI-6122 supports PXI timing and triggering resources for coordinating measurements with other modules in an automated test system.\n<\/p>\n<p>\nThe module provides access to seven PXI trigger lines and the PXI Star Trigger, allowing acquisition events to be coordinated with compatible PXI instruments.\n<\/p>\n<p>\nThis capability is useful in systems combining data acquisition with oscilloscopes, signal generators, switching modules, digital instruments, or other synchronized measurement hardware.\n<\/p>\n<h3>Software Ecosystem<\/h3>\n<p>\nThe NI PXI-6122 is supported by the NI-DAQmx software ecosystem for measurement, timing, triggering, digital control, and automated testing.\n<\/p>\n<ul>\n<li>\n<strong>NI-DAQmx:<\/strong> Provides APIs for analog acquisition, digital I\/O, counters, triggering, and

Compatible cables and terminal blocks should be selected according to the application and required signal connections.\n<\/p>\n<h4>What is the difference between PXI-6122 and PXI-6123?<\/h4>\n<p>\nBoth are S Series simultaneous-sampling multifunction DAQ modules. The PXI-6122 provides four analog input channels, while the PXI-6123 provides eight analog input channels. The PXI-6122 is suitable when four synchronized channels are sufficient, while the PXI-6123 is preferable when additional simultaneous analog inputs are required.\n<\/p>\n<h4>What is the difference between PXI-6122 and PXI-6143?<\/h4>\n<p>\nBoth provide 16-bit simultaneous-sampling analog acquisition. The PXI-6122 provides four analog inputs at up to 500 kS\/s per channel, while the PXI-6143 provides eight analog inputs at up to 250 kS\/s per channel. The choice therefore depends primarily on whether the application prioritizes higher per-channel sampling speed or additional simultaneous channels.\n<\/p>\n<h4>What applications is the PXI-6122 designed for?<\/h4>\n<p>\nTypical PXI-6122 applications include IF digitization, transient recording, ISDN, ADSL and POTS manufacturing test, ultrasound and sonar testing, high-energy physics, synchronized signal acquisition, and automated measurement systems.\n<\/p>\n<h4>Is the NI PXI-6122 discontinued?<\/h4>\n<p>\nThe PXI-6122 is no longer available for purchase directly from NI and is currently classified as a <strong>Limited Support<\/strong> product. It remains relevant for maintenance, replacement, and expansion of existing PXI systems that use S Series DAQ hardware.\n<\/p>\n<h4>What should I check before purchasing a replacement PXI-6122?<\/h4>\n<p>\nBefore purchasing a replacement module, verify the exact model and part number, PXI chassis compatibility, 68-pin cable and terminal block requirements, NI-DAQmx software compatibility, and whether the application specifically depends on the PXI-6122 simultaneous-sampling architecture.\n<\/p>\n<h3>\u0417\u0430\u043a\u043b\u044e\u0447\u0435\u043d\u0438\u0435<\/h3>\n<p>\n\u0417\u0435\u043c\u043b\u044f <strong>NI PXI-6122 Simultaneous-Sampling Multifunction I\/O Module<\/strong> provides four differential analog inputs, 16-bit resolution, 500 kS\/s per-channel sampling, eight bidirectional digital I\/O lines, two 24-bit counter\/timers, analog and digital triggering, and PXI synchronization capabilities.
