The PXI-6289 is a multifunction Data Acquisition (DAQ) device designed for the PXI platform, offering a versatile solution for a wide range of measurement and control applications. This model comes with part numbers 779639-01 for the PXI hybrid bus connector and 779123-01 for the PXI bus connector, indicating its compatibility with different PXI chassis configurations.
It features 32 analog inputs (AI), which can be configured as either 16 differential or 32 single-ended channels, providing flexibility in connecting various sensors and signals. Additionally, the PXI-6289 boasts 48 digital I/O (DIO) lines, 4 analog outputs (AO), and two 32-bit counter/timers, making it a comprehensive tool for handling complex data acquisition and control tasks.
The device offers an 18-Bit resolution for precise measurement and a maximum sample rate of 625 kS/s, ensuring accurate and rapid data collection. In multichannel mode, the sample rate is 500 kS/s, suitable for simultaneous measurements across multiple channels. The timing resolution and accuracy are 50 ns and 50 ppm respectively, further enhancing measurement precision.
For connectivity, the PXI-6289 supports various data transfer methods including DMA (scatter-gather), programmed I/O, and interrupts, facilitating efficient data movement. It also provides robust overvoltage protection of ±25 V for up to eight AI pins, safeguarding the device from unexpected voltage spikes. The input impedance is >10 GΩ (AI+ to AI GND), and similarly >10 GΩ (AI- to AI GND) in parallel with 100 pF, ensuring high resistance against unwanted signals.
Triggering options are versatile, including both analog and digital triggers, which allow users to initiate measurements or actions based on specific signal conditions. The device requires a recommended warm-up time of 15 minutes for optimal performance and has a calibration period of at least once in 2 years, ensuring
