The PXIe-1081 is an 18-slot PXI Express chassis for cost-optimized measurement and test systems with many channels and low data rates. With 17 hybrid slots, up to 58 W cooling power per slot and a system bandwidth of 2 GB/s (PCIe Gen 1), it is ideal for high-channel, parallel applications such as data acquisition, parameter tests and monitoring. Especially for modules with low to medium throughput requirements - such as DAQ cards, DMMs, SMUs and switching modules - the PXIe-1081 offers a cost-effective entry into 18-slot PXIe systems and at the same time benefits from the NI PXI ecosystem with integrated software, modern controller support and powerful timing and synchronization technology.
