Industrial PC VPC-3100-G
With the analog E series, sampling speed was sometimes limited because the data transfer on the bus could not keep up when sampling continuously for a long period of time. With the analog G series, the DMA bus master transfer function eliminates data transfer bottlenecks and enables continuous data acquisition at full-spec 1MSPS for long-term continuous sampling.
With the continued transition from 32-bit versions to 64-bit versions of Windows, specifications on the OS side mean 64-bit versions are able to secure only a small amount of buffer memory for data transfers (1 MB or 2 MB), preventing the DMA transfer function from being utilized to its full potential. The Analog G Series has native compatibility with both PCI Express and 64-bit OS versions for enabling improved performance with a large-capacity transferrable memory allocation of up to 2 GB. This eliminates data transfer bottlenecks and enables continuous data acquisition at the full 1 MSPS for continuous sampling over extended periods.
This enables not only faster continuous sampling, but also faster execution processing times for functions that acquire and output analog data in single shots. Because function processing is returned immediately, this allows for shorter takt time in applications that alternate between measurement and control, such as product testing.
