The NI PXI-1052 is a 12-slot hybrid chassis integrating a 4-slot PXI subsystem with an 8-slot SCXI subsystem. This architecture enables seamless measurement and automation applications combining PXI instrumentation with SCXI signal conditioning. The built-in digital and analog bus between subsystems allows a DAQ/DMM module in the fourth PXI slot to control SCXI modules without additional cabling in multiplexed mode, creating a low-noise environment for advanced signal processing.
