- Pickering Interfaces, supplier of modular switching and signal simulation solutions for electronic test and validation, has announced its new 42-927 Series fully hybrid PXIe chassis with 21 slots: one PXIe system slot and 20 hybrid peripheral slots.
The chassis features a 21-slot PXIe backplane and accepts standard PXIe (PXI Express) or hybrid PXI-compatible modules in all slots. The PCIe Gen2 bus offers system bandwidth of up to 8 Gb/s and slot-to-slot bandwidth of up to 2 Gb/s. PCIe switching is provided via the default four-link (4×4) PXIe system slot. The chassis uses three PCI segments with a dedicated PCIe-to-PCI bridge module for hybrid slots. PXI clocks and trigger signals are generated and controlled by an independent clock module attached to the rear of the backplane.
“Combined with our new 43-920-001 series single-slot embedded controller, this new chassis offers unrivalled rack density for signal switching,” said Lee Huckle, chassis product manager at Pickering Interfaces. “The chassis accepts standard PXIe or PXI modules in its 20 hybrid device slots, the highest number of slots of any chassis currently available on the market. This makes it possible to support up to 15,360 crossover points using our BRIC-format PXI matrices and multiplexers. ”
Equipped with two replaceable 900 W EMC Class B industrial-grade power supplies (PSUs) mounted on the rear, the chassis can provide up to 80 W of power to each slot. This enables support for PXI modules involving high currents.
A chassis operation management system monitors power supply voltage, internal temperature and cooling fan speed. Chassis operating parameters can be remotely monitored via a port on the rear panel. Three 120 mm fans ensure optimum cooling of the PXI modules. The direct convection design enables the chassis to operate over an ambient temperature range from 0°C to +55°C. Two exchangeable power supplies and a removable rear cassette make the chassis easy to service and maintain.
