NI PXI-1011 PXI/SCXI Chassis

The National Instruments PXI-1011 is a dual-subsystem chassis integrating 4 PXI slots with 8 SCXI slots in a single compact unit. This configuration enables direct interconnection between signal conditioning (SCXI) and high-performance measurement (PXI) domains, with SCXI control routed through the 4th PXI slot to eliminate external cabling. The chassis supports embedded controllers, external PC connectivity via MXI-3 interface, and a full range of analog/digital conditioning and measurement modules.

– Key Features

• Integrated PXI/SCXI interconnection eliminates separate control cabling
• Advanced synchronization and timing support across both subsystems
• Overcurrent and overvoltage protection built-in
• Daisy-chaining capability for expanding SCXI signal-conditioning capacity
• Flexible mounting: benchtop or standard 19-inch rack with six position options
• Wide input voltage and frequency range for global deployment

– Typical Applications

• Multi-channel data acquisition with integrated signal conditioning
• Analog and digital measurement systems requiring mixed-signal control
• Test platforms combining isolated sensor inputs (SCXI) with high-speed measurements (PXI)
• Distributed signal monitoring with daisy-chained conditioning modules

– Compatibility & Integration

Accepts MXI-3 interface modules, embedded controllers, and standard PXI modules including digital I/O (DIO) and multifunction I/O (MIO). SCXI subsystem accommodates multiple conditioning modules for analog input, digital input, isolation, and specialized functions. Software configuration via NI-DAQmx or traditional NI-DAQ for SCXI operation.
