USB module increases sampling rate
Staff -- Test & Measurement World, 4/1/2006
Data Translation continues to expand its line of USB data-acquisition modules, this time reaching a new high for sampling rate: 2 Msamples/s on each channel. The DT9832A has two 16-bit analog inputs, each with its own analog-to-digital converter. It also contains two 500-ksample/s analog outputs (optional), 32 digital I/O lines (16 in/16 out), two timer/counters, and three quadrature decoders. A companion model, the DT9832, has four analog inputs that can sample at 1.25 Msamples/s on each channel.
If you don't need all analog-input channels but need high-speed digital I/O, you can set up the digital inputs so they all clock at the 2- or 1.25-MHz sample rate when you set up a channel-scan list.
Software support includes drivers for Windows 2000/XP and for LabView, Matlab, and Visual Basic. Both modules are available packaged with BNC and D-sub connectors or as unpackaged OEM versions.
Base price: $1970. Data Translation, www.datatranslation.com .
