Description
The National Instruments PXI-1045 PXI Chassis is a robust and versatile 18-slot chassis, offering a system bandwidth of 132 MB/s and compatibility with NI PXI chassis software and NI Measurement & Automation Explorer (MAX). It features part numbers 778645-01, 778644-01, and 778644-02 for chassis and rack mounting kits, although there may be a discrepancy in the provided information for the rear mounting kit, suggesting a closer review of part numbers 778645-02, 778644-02, or 778645-01 may be necessary.
This chassis includes two BNC I/O connectors for reference input and output and is equipped with a low-jitter 10 MHz framework reference clock that ensures less than 250 ps skew between slots, optimizing device synchronization and phase-locked measurements. The cooling system is managed by a selectable AUTO/HIGH fan speed, providing up to 25 W of cooling capacity per slot at low speed and 24 W at high speed, while the AUTO setting adjusts fan speed based on intake air temperature to balance cooling needs with acoustic emissions.
For maintenance and upgrades, the chassis’s AC power supply can be replaced with part number 778647-01. The unit weighs 27.8 lb and has compact dimensions, making it suitable for various installation environments. Please note that the dimensions were not fully provided in the specification table.
