NATIONAL Instruments new software-configurable 18-slot PXI chassis can be used to programmatically configure precise timing and synchronisation signals between modular instruments.
With configuration and driver software such as NI measurement and automation explorer and NI-DAQ 7, engineers can increase system performance and reduce test times by configuring trigger routing modules on the backplane of the chassis to reserve trigger lines or route triggers to and from any of the chassis' three bus segments.
The new NI PXI-1045 18-slot chassis features a wide operating temperature range of 0 to 55°C for environments with extended temperature conditions.
The CompactPCI-compatible chassis features a high-precision, low-jitter 10MHz reference clock with slot-to-slot skew of less than 250 picoseconds for device synchronisation.
For importing or exporting system reference clocks, the rear of the chassis includes two BNC I/O connectors. Engineers can configure up to 5,000 channels of 24-bit dynamic signal acquisition by synchronising multiple PXI-1045 chassis with the NI PXI-6653 timing and synchronisation module.
For secure 19” rack mounting, the PXI-1045 chassis offers optional front and rear rack mount kits.
The new chassis is suitable for test and measurement applications requiring software configurable triggering, high channel counts and tight synchronisation between high-performance modular instruments.
The unit’s extended operating range temperature makes it suited for applications in military/aerospace, manufacturing test and industrial monitoring.
The chassis works with all 3U PXI hardware devices and NI software including LabVIEW 7 express graphical development environment, TestStand test management software and measurement studio for Visual Studio .NET.
PCI extensions for Instrumentation (PXI) is an open specification governed by the PXI Systems Alliance that defines a rugged, CompactPCI-based platform for measurement and automation.
