Data Acquisition Units For PCI Express And PXI Express Support Multicore CPUs

A family of 16 multifunction data acquisition (DAQ) devices serves PCI Express and PXI Express applications. Part of the company’s X Series of DAQ devices, the new models provide enhancements to analog I/O, digital I/O, onboard counters and multi-device synchronization. X Series DAQ devices, which include up to 32 analog inputs, four analog outputs, 48 digital I/O lines and four counters, range from 250-kS/s multiplexed analog inputs to 2-MS/s simultaneous sampling analog inputs. Simultaneous X Series devices integrate up to 16 ADCs on a single device at 2 MS/s per channel, so engineers can sample all analog-input channels at a high rate and with minimal phase offset; total analog-input throughput is up to 64 MB/s. The DAQs also include independent timing engines for the onboard analog and digital I/O subsystems, so engineers can execute analog and digital I/O independently at different rates or together with synchronization. X Series devices include four enhanced 32-bit counters for frequency, pulse-width modulation (PWM) and encoder operations and a new 100 MHz timebase that can generate analog and digital sampling rates with five times better resolution than previous devices. Using the multithreaded NI-DAQmx driver software and NI LabVIEW graphical programming enables engineers to easily create applications that execute on multicore processors for higher performance and more advanced analysis and data visualization. Pricing for the X Series DAQs starts at $499 each. NATIONAL INSTRUMENTS, Austin, TX. (888) 280-7645.
