8-way AI (16-bit, 500 kS/s/ch), 8-way DIO, PXI multi-function I/O module

PXI‑6123 is a synchronous sampling multi-function data acquisition device. It provides analog inputs, digital I/O, two 24-bit counters, and digital triggers. PXI‑6123 is suitable for many applications, such as IF digitization; Instantaneous recording; ISDN, ADSL and POTS manufacturing tests for the communications industry; Ultrasonic and sonar testing and high energy physics. The included NI‑DAQmx driver and configuration utility simplify configuration and measurement.

The National Instruments PXI-6123 (Part number: 779181-01 and 779180-01) multi-function I/O module features several types of channels, including: 8 analog input channels, 8 DIO channels, 2 counters, and does not contain any analog output channels. The module also has a sampling rate of 500 kS/s, a 16-bit resolution and an absolute accuracy of 4.96 mV. For best performance, the recommended warm-up time is 15 minutes. There is also a calibration interval of two years, and specifications for that time period are guaranteed. The self-calibration process is very simple because it utilizes the self-calibration algorithm NI-MCal to characterize nonlinearities, misalignments, and gain errors in the module. The self-calibration process takes only a few seconds to complete. The NI module features I/ O customization options, NI-STC3 timing technology, the ability to transmit information using PCI Express, and programmable input gain to take full advantage of resolution.

The PXI-6123 multifunction I/ O module includes a powerful NI-DAQmx driver with an API that works with DAQExpress, C, C#, Python, LabVIEW and other development options. This integration provides amazing performance and an effortless experience without the need for manual packaging functions. The NI-DAQMX driver API is used for all NI DAQ models to ensure extended interoperability of the DAQ models. This means that despite hardware changes or upgrades, less redevelopment work can be done, making the whole process simpler. The NI-DAQmx driver also provides users with help logging, documentation, and a number of actionable tools that can be used as a starting point for user applications.
