Description
The National Instruments PXIe-4309 PXI Analog Input Module, with Part Number 784471-01, is a highly capable device offering up to 32 differential channels for data acquisition. This module is equipped with eight simultaneous sampling ADCs, allowing for a maximum sampling rate of 2 MS/s per channel or a total maximum sampling rate of 400 kS/s. Moreover, it boasts an impressive resolution range from 18 bits at the highest sampling rate to 28 bits at a lower rate of 2 S/s per channel, ensuring precise measurements.
High levels of noise rejection are achieved through the pairing of two channels, which is critical for making accurate and repeatable nano-volt measurements. Users can choose between two sampling modes: “averaging” for more stable readings, and “single sample” for quick, individual measurements.
The module operates in two primary timing modes, namely, software-timed mode which utilizes on-demand timing for static acquisitions, and hardware-timed mode that relies on an AI Sample Clock. This clock can be generated internally or can be exported to synchronize with other devices, ensuring efficient data collection with minimum delay between samples.
