# Introduction

Take your testing and measurement applications to the next level with the ADLINK PXES-2788 chassis. With its high-performance 18-slot PXI Express backplane, high-output power supply, and cooling capacity, the PXES-2788 is designed for heavy-duty and high port density applications. The modular design ensures a high level of maintainability, with replaceable power supplies for highavailability applications, resulting in a very low meantime to repair (MTTR).

Fully compliant with the PXI-5 PXI Express hardware specification, the PXES-2788 offers advanced timing and synchronization features for high clock accuracy, and external clock and trigger routing. Using PCI Express 3.0 technology, the chassis boasts a system bandwidth of up to 24 GB/s for high-throughput, peer-to-peer data transfer applications, and up to 8 GB/s bandwidth for all peripheral slots.

The PXES-2788 provides up to 102W power and cooling capacity per slot, allowing for higher power budgets for high-performance and power PXI modules. With a smart system monitoring controller that reports chassis status, including fan speed, system voltages, and internal temperature, you can be sure that your system is running at optimal performance. The smart fan function dynamically adjusts fan speed based on the embedded temperature sensor to achieve a balance between sufficient airflow and operating noise.

Experience the power and versatility of the ADLINK PXES-2788 chassis and take your testing and measurement applications to the next level.
