Description
The PXI R Series, specifically the PXI-7842R LX50 R Series, is a sophisticated piece of equipment equipped with a part number 198219-05 (780338-01). This device stands out for its integration of 8 Analog Input (AI) channels and 8 Analog Output (AO) channels. The AO channels are particularly notable for their 16-bit, single-ended, voltage output with a +10V range and a maximum update rate of 1 MS/s.
Moreover, it boasts an impressive 96 Digital Input/Output (DIO) channels, which support both 3.3 V TTL and 5 V TTL logic levels, providing flexibility for various digital communication needs. At its core, the PXI-7842R LX50 R Series utilizes a Virtex-5 LX50 onboard Field-Programmable Gate Array (FPGA), enhancing its processing capabilities and allowing for high-level customization.
The device employs a successive approximation ADC type with a 16-bit input resolution, ensuring precise data acquisition. The A/D conversion time is remarkably swift at 4 µs, enabling the system to achieve a maximum sampling rate of 200 kS/s for analog inputs. Its small signal bandwidth is rated at 1 MHz, complemented by a minimum sampling time of 5 ns for digital I/O, showcasing its efficiency in handling high-speed signals.
Compatibility with NI-RIO driver software is provided, ensuring seamless integration and ease of use within setups running Windows XP/2000 and LabVIEW RT operating systems. Additionally, it supports the LabVIEW FPGA Module, offering extended functionalities for users seeking to leverage LabVIEW’s comprehensive development environment for FPGA programming.
Finally, the PXI-7842R LX50 R Series has been announced by National Instruments and is available at Apex Waves. Its mature status signifies a reliable and well-supported platform for a wide range of applications requiring high-speed data acquisition and real-time processing capabilities.
