With the DT9816 series Data Translation offers a range of low-cost USB data acquisition modules for simultaneous sampling of up to six analog signals. Unlike comparable measurement instruments in the same price range, these modules feature separate 16-bit A/D converters per input channel instead of multiplexed inputs. This eliminates phase shifts and allows simultaneous, synchronous measurements on multiple inputs - thus offering significant advantages for measurement speed and accuracy. The series provides different models, from the proven DT9816-S with a sampling rate of up to 750 kHz per channel, to the DT9816 with 6 x 50 kHz and the DT9816-A with 6 x 150 kHz. The compact, rugged data acquisition modules run entirely on USB power so that no external power supply is needed. This makes them good for portable measurement and test applications. Screw terminals on the module allow easy signal connections. In addition to the six analog inputs, all models of the series also provide 16 digital inputs and outputs. A counter/timer supports frequency measurements, rate generation and other operations. The modules of the DT9816 series are available at a starting price of EUR 460. In addition to providing simultaneous data acquisition at an economical price, they effectively eliminate error caused by settling time, crosstalk or phase shifts which are inherent when switching between channels. Accuracy now is independent from the signal source impedance.
