Signal-capture boards
Staff -- Test & Measurement World, 2/1/2007
UK-based DataQuest Solutions has extended its Spectrum M2i range of PCI/PCI-X, CompactPCI, and PXI signal-capture boards to include the 16-bit M2i.46xx series, which feature capture rates up to 3 Msamples/s on up to eight input channels.
The boards capture signals with over 14.5 effective bits for a wide combination of speed and input ranges from ±50 mV to ±10 V. Internal RMS input noise level is in the microvolt region on higher ranges. Each channel uses its own ADC to provide true differential or single-ended input. To enable long capture periods, the boards include 64 Mbytes of storage, which you can expand to 4 Gbytes. Alternatively, you can use the storage as a FIFO buffer for real-time transfers to a PC. The boards operate in PCI or PCI-X slots with 3-V and 5-V I/O voltages. DataQuest Solutions, www.dqsolutions.co.uk/boardpagead.htm.
