Description
The PXI-6259 is a multifunction Data Acquisition (DAQ) device designed for a wide range of applications. It comes with a variety of part numbers, including 191325B-01L, 779632-01, and 191325F-01L, ensuring flexibility and compatibility for different systems.
This high-performing DAQ device falls under the category of PXI Multifunction DAQ, which is known for its reliability and high-speed data acquisition capabilities. It boasts an impressive array of 16 differential or 32 single-ended analog input channels, each with a 16-Bit resolution and a maximum sampling rate of 1.25 MS/s. This allows users to capture high-quality data from a variety of sensors and inputs.
In addition to analog inputs, the PXI-6259 is equipped with 48 digital I/O channels, providing extensive interfacing capabilities with external devices. It also offers 4 analog output channels for generating signals or controlling other equipment.
The device includes two 32-bit timers/counters and 6 DMA channels, enhancing its performance in applications requiring precise timing and high-throughput data streaming. With seven programmable input ranges per channel, it can accommodate a wide range of signal levels, from small sensors to high-voltage sources. The PXI-6259 also supports quadrature encoder inputs (X1, X2, X4), allowing it to directly interface with rotary encoders for position and motion control applications.
The maximum operating voltage for analog input ground (AI GND) is ±11 V, and the input impedance is exceptionally high (>10 GΩ in parallel with 100 pF), minimizing the loading effect on measured circuits. This device also features a fine timing resolution of 50 ns, enabling precise control and synchronization of external devices.
Calibration is an essential aspect of maintaining the accuracy of the PXI-6259, with services available annually or every two years. It incorporates NI-MCal calibration technology, ensuring reliable performance over time. Software compatibility is broad, supporting
