Product Overview

The National Instruments PXIe-1085 is an 18 slot PXI Express chassis for high performance test and measurement systems. It provides a large number of slots for PXI Express instruments, controllers, and modules. The chassis is designed for automated test, laboratory research, production verification, and multi instrument systems that require high bandwidth and flexible configuration.

The PXIe-1085 is part of the NI PXI platform. It supports a wide range of PXI Express modules, including digitizers, signal generators, switches, source measure units, and data acquisition devices. The chassis includes cooling and power resources for demanding modules and supports the timing and synchronization features of the PXI Express backplane.

Slot Count and Backplane

The PXIe-1085 provides 18 slots for PXI Express modules. One slot is typically used for an embedded controller or remote control module, and the remaining slots are available for instruments and I/O. The high slot count allows a complete test system to be built in one chassis, which reduces external cabling and improves integration.

The backplane provides high bandwidth connections between the controller and the installed modules. This is important for high speed data acquisition, RF measurement, and multi channel test systems. The chassis supports PXI Express timing and trigger lines, allowing modules to be synchronized for coordinated measurement and control.

Cooling and Power

The PXIe-1085 includes cooling and power resources designed for high performance PXI Express modules. Adequate airflow and power delivery are important when the chassis contains multiple instruments that generate heat. Engineers should verify the power and cooling requirements of each installed module and ensure that the total system remains within the chassis specifications.

The chassis is designed for rack mounting and laboratory use. Proper installation and ventilation help maintain reliable operation. The power supply and fan system are sized to support a range of module configurations, but high power modules may require careful slot placement and thermal planning.

System Integration

The PXIe-1085 can be used with an embedded controller or a remote control module. It supports NI software and drivers for PXI Express instruments. Engineers can configure and program modules with LabVIEW, LabWindows/CVI, Measurement Studio, and other compatible development environments.

The chassis can be integrated into larger test systems through Ethernet, USB, or other interfaces available on the controller. It supports synchronization with external devices and other PXI chassis where the system architecture allows. The combination of high slot count, high bandwidth, and PXI Express timing makes the chassis suitable for complex test and measurement applications.
