National Instruments PXI-7851 PXI Multifunction Reconfigurable I/O Module
The PXI-7851 (Part Number: 780339-01) has a client programmable FPGA for superior interior preparing and direct control of I/O signals for an entire adaptability of timing and framework synchronization. The user can redo these gadgets with the LabVIEW FPGA Module to create applications that require exact planning and control, such as equipment testing, custom correspondence convention, sensor recreation, and fast control. This model has a devoted A/D converter (ADC) per channel for autonomous planning and activating. This plan offers specific usefulness, including factor speed inspecting and singular channel activating, which are past the span of run of the mill information obtaining equipment. The device has 8 analog inputs (with a 16-bit resolution and a sampling rate of 750 kS/s), and 8 analog outputs (with a 16-bit resolution and a sampling rate of 1 MS/s). Additionally, it has 96 digital I/O lines, with 3 DMA channels.
The NI PXI-7851 Multifunction Reconfigurable I/O Module comes with an NI PXI Testing System of Analog-Digital Converter, which incorporates the key instruments to portray ADCs with resolution up to 14 bits and sample rates of 200 MS per second. The framework joins a discretionary waveform generator to create simple test examples to an ADC, rapid advanced I/O to catch ADC yields, and produce regular correspondence conventions (SPI, I2C, JTAG), a unit of estimation of Source (SMU) for normal DC parametric estimations (open/short, spillage tests), and a module for steering DC instrumentation to different test focuses. The ADC PXI Test System arrangement has the instruments the user needs to perform regular estimations on ADCs including INL, DNL, SNR, THD, IDD, IDDQ and high/low voltage edge tests. Joined with NI LabVIEW programming, this arrangement can help users rapidly alter their framework to play out the particular estimations they have to portray an ADC.
The device is equipped with 3 68-pin female high density VHDCI I/O connectors. The NI device weighs 0.33 lb, and measures 6.3 x 3.9 in. in physical dimensions. It has a recommended operating temperature range of 0 °C to 55 °C.
PXI-7851 Mature Status has been announced by National Instruments, but the module will still be available for purchase and repairs by Apex Waves.

National Instruments PXI-7851 Frequently Asked Questions
Question: Does the PXI-7851 have a dedicated A/D converter?
Answer: The PXI-7851 has one dedicated A/D converter per channel.
Question: Can I have two AI channels sampling with different rates on the NI PXI-7851 module?
Answer: No, the NI PXI-7851 has a single analog timing engine, so it is limited to one sample rate.
Question: Does the PXI 7851 offer multi-rate sampling?
Answer: You can achieve multi-rate sampling, as well as individual channel triggering with the PXI 7851.
