Adlink’s PCIe-9852 digitizer board offers two simultaneously sampled 200-Msample/s input channels with 14-bit resolution, 90-MHz bandwidth, and up to 1 Gbyte of DDR3 memory. Data streaming at up to 800-Mbytes/s and onboard signal averaging make the PCIe-9852 useful for long-term, high-speed data recording in distributed temperature sensing, radar signal testing, and atmospheric science research.
Each channel of the PCIe-9852 has its own 14-bit ADC with a spurious-free dynamic range of 83 dB, signal-to-noise ratio of 62 dB, and total harmonic distortion of –81 dB. The analog input is designed to receive ±0.2-V, ±2-V, and ±10-V signals with software-selectable 50-O and 1-MO input impedance. Onboard signal averaging allows the detection of small repetitive signals in noisy environments, with no CPU loading.
Compliant with PCI Express Rev. 2.0 specifications, the board streams data on both channels at the maximum data rate (200 Msamples/s), enabling continuous delivery to the host PC at rates of up to 800 Mbytes/s. A complementary 8×500-Gbyte RAID system extends capture sessions beyond one hour.
Measurement cards for desktop PCs seem to have a lot of life left, even though the consumer world is pretty much all laptops and tablets. What might happen if/when desktop PCs are a thing of the past? Well industrial PC suppliers will still be around. Some still have legacy ports. At least the parallel port is dead. See The Mother(board) of Connectivity for more.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
