PXI hybrid slot compatibility

Article about the compatibility of Spectrum PXI card with PXI/PXIe hybrid slots as used by many chassis vendors

PCI Express Lanes

In contrast to the parallel PCI buses PCI and PXI Express slots contain serial point to point connections. Each connection pair (lane) is able to reach a burst connection speed of 250 MBytes/s. One advantage of the PCI/PXI Express technology is the direct connection of each slot allowing a full transfer bandwidth for each single card.

PCI Express Platform

PCI Express is the standard platform for all current PC based systems and also for the future. The PCI Express bus is a point to point connection allowing full speed for every single slot.

PCI and PCI-X Platform

General information on the PCI and PCI-X bus and Spectrum digitizer and generator products based on PCI/PCI-X

PXI 3U Platform

Based on the CompactPCI 3U standard the PXI (PCI eXtensions for Instrumentation) enhancement was defined especially for the measurement user. In this specification additional lines for measurement purposes are defined.

cPCI 6U Platform

CompactPCI combines the advantages of the PCI bus with the needs of the industrial user. CompactPCI uses wellknown and stable 19? technology and offers robust systems for industrial needs.

PXIe 3U Platform

PXI Express or PXIe is a subset of the PXI standard that replaces PXI?s parallel data bus with a high speed serial interface. PXIe provides the most advantages for modular instruments like digitizers or arbitrary waveform generators which often need to transfer large amounts of data. For example, state-of-the-art PXIe products from Spectrum incorporate a fast interface that can stream at rates of up to 1.7 GB/s.

M4i.22xx Transfer speed and speed test results

The article explains the limitations of the M4i.22xx series continuous streaming transfer speed and the results shown in the Spectrum control center. It is explained why you see different results in comparison to the figures mentioned in the data sheet.
