National Instruments PXI-7833R PXI Multifunction Reconfigurable I/O Module

The National Instruments PXI-7833R (Part number: 779360-01) has eight 16-bit AI channels, eight 16-bit AO channels, 96 bidirectional DIO lines that the user can configure independently for inputs or outputs, and a Virtex-II 3M gates FPGA. The driver software for the NI PXI-7833R is NI-RIO. When the NI PXI 7833R is configured in DIFF input mode, each channel utilizes two AI lines. The positive input stick interfaces with the positive terminal of the locally available instrumentation intensifier, and the negative information stick associates with the negative input of the instrumentation enhancer. When the PXI-7833R Multifunction RIO Module is active, each channel utilizes only the positive AI stick. This stick interfaces with the positive terminal of the installed instrumentation enhancer. The negative input of the instrumentation intensifier is inside fixing to the AI ground (AIGND).

When the framework control is on, the DIO lines are for the most part high-impedance. To set another power-on state, the user can configure the PXI-7833R to consequently load to VI when the framework control is on.

The Multifunction RIO Module can send and get triggers through the PXI trigger bus, which gives eight trigger lines that connect to the PXI slots in a bus section. These trigger lines interface with the FPGA on the PXI-7833R and can be utilized simply like any of the other DIO lines. The PXI trigger lines can be utilized to synchronize the NI PXI 7831R to whatever other gadget that backs PXI triggers. Additionally, the PXI-7831R can utilize the PXI star trigger line to send or get triggers from a gadget connected to slot 2 of the PXI frame.

PXI-7833R Obsolete Status has been declared by National Instruments, but the module will still be available for purchase and repairs by Apex Waves.
