High-Performance Data Acquisition on USB Written by: Tim Ludy | Distributed: 2006-03-28 | A common belief among engineers is that, to get the best performance, a PC based data acquisition module must plug into the PCI bus. Properly implemented, however, a data acquisition module can use the PC's USB 2.0 port to pump data into a PC as fast as PCI-based cards.

The Battle for Data Fidelity: Understanding the SFDR Spec Written by: Tim Ludy | Distributed: 2006-03-22 | As A/D converters (ADC) and data acquisition boards increase their bandwidth, more and more are including the spurious free dynamic range (SFDR) specification as an indicator of their fidelity. The converter is not the only source of spurious signals; however, because of complex interactions between the ADC and the signal conditioning circuits that invariably precede it.
