NATIONAL Instruments has released the PCI-6225 and PXI-6225, members of the low-cost M series data acquisition (DAQ) family that offer 80 16-bit analogue input channels with sampling rates up to 250kS/s. The 6225 devices are suitable for applications such as data logging, control and sensor measurements.
National Instruments’ MCal technology increases accuracy across the entire measurement range by performing a self-calibration at each input range and compensating for nonlinearity error. The NI-STC 2 system controller chip delivers digital I/O and timing capabilities previously unavailable with plug-in DAQ devices, such as timed and correlated digital I/O. The chip also provides 32-bit counter/timers with quadrature encoder inputs and debouncing filters, as well as six DMA channels for dedicated data paths to the PC processor for all I/O operations.
The PCI-6225 and PXI-6225 include two analogue output channels, 24 digital I/O (DIO) lines, hardware-timed digital I/O at rates up to 1MHz on eight DIO lines and two 80MHz, 32-bit counter/timers. NI ships both devices with its measurement services software, a collection of tools and drivers that connects virtual instrumentation software, such as National Instruments’ LabVIEW, with NI hardware for measurement and control. NI measurement services software, built around NI-DAQmx driver software, includes intuitive application programming interfaces, configuration tools, rapid I/O assistants and professional tools to help engineers reduce system setup and configuration time.
