PCI/PXI DAQ Boards Ratchet Up Performance

Reporting performance levels comparable to high-end instrumentation, the PCI-6143, PXI-6143, PXI-6133, and PXI-6132 are simultaneous sampling data-acquisition boards that are designed to deliver better measurement accuracy at a lower cost per channel than previous models. The NI PCI-6143 and PXI-6143 DAQ boards provide eight-channels and sample at 250 ksamples/s with a 16-bit resolution. They also feature digital triggering, eight digital I/O lines, and two 24-bit counter/timers. The NI PXI-6133 and PXI-6132, with eight and four channels, respectively, specify a sampling rate of 2.5 Msamples/s with a 14-bit resolution. Accommodating a wider range of applications, they accept input voltages from ±1.25V to ±10V and include up 32 Msamples of memory. Other features include analog and digital triggering, eight hardware-timed digital I/O lines, and two 24-bit counter/timers. Single-unit pricing starts at $995. NATIONAL INSTRUMENTS, Austin, TX.
