PXI-8840

The NI PXI-8840 is an embedded system controller for PXI modular instrumentation and data acquisition systems. Processor and operating-system configurations vary; the catalog-associated part number 784193-33 identifies a quad-core LabVIEW Real-Time configuration rather than the Core i5 Windows configuration described in the legacy record.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the PXI-8840 a measurement module or a controller?

It is an embedded PXI system controller that provides computing and peripheral connectivity for a modular instrumentation system.

Which configuration does part number 784193-33 identify?

NI identifies 784193-33 as a PXI-8840 quad-core Core i7 configuration with LabVIEW Real-Time (Phar Lap). This conflicts with the catalog's legacy Core i5 and Windows 7 description, so the actual unit configuration requires confirmation.

What peripheral connections are provided?

NI lists two Gigabit Ethernet ports, two USB 3.0 ports, four USB 2.0 ports, and a serial port. Configuration-dependent expansion features should be checked against the exact controller variant.
