Description
The PXIe-7857R and 784146-01 are part of the PXI R Series designed to deliver high performance and versatility for various applications. These devices come equipped with 512MB DRAM memory, ensuring efficient data handling and storage capabilities. At their core, they utilize the powerful Kintex-7 160T FPGA, which provides the computational power and flexibility needed for complex signal processing tasks.
With a 16-bit resolution, these devices ensure high precision in data acquisition and output. They are capable of a maximum sampling rate of 1MS/s, allowing for the capture of fast transient signals without sacrificing detail. The devices feature 48 digital I/O channels, 8 analog input channels, and 8 analog output channels, offering ample connectivity for a wide range of sensors and actuators.
The Successive Approximation Register (SAR) ADC Type employed in these devices provides reliable and accurate analog-to-digital conversion. Input impedance in the powered-on state is 1.25 GΩ ‖ 2 pF, and in the powered-off state, it is a minimum of 4 kΩ, ensuring compatibility with a variety of signal sources. The output voltage range of ±10 V allows for a wide range of output signals to be generated.
Connectivity is facilitated through two 68-pin VHDCI connectors, making it easy to integrate these devices into existing setups. The dimensions of 18.5 cm × 17.3 cm × 3.6 cm and a weight of 170.9 g make them compact and lightweight, ideal for setups where space is at a premium.
