May 11, 2010 - Data Translation announces the DT 9837B USB data acquisition module for noise, vibration and sonar measurement applications. The DT 9837B module features four analog inputs that support the use of a 4mA current source for IEPE/ICP sensors and a tachometer input for measurements from rotating components. Exceptionally, with sampling rates up to 105.4 kHz per channel, the new module offers twice the sampling rate of its family members.The instrument has a compact, paperback sized design. It runs entirely on USB power, making it ideal for portable use with a notebook. The IEPE configuration is stored directly in the module so that it is ready to measure right after power-up.The four analog inputs are each provided with a 24-bit Delta-Sigma A/D converter for ultra-accurate measurements. The 4mA current source for the IEPE/ICP sensor, AC or DC coupling and gains of 1 and 10 are all individually programmable per channel. The additional tachometer input can measure rotational speeds and also be used for phase measurements between the tachometer input and the A/D samples, achieving a resolution of 37 ns (0.002 degrees) at up to 10,000 rpm. For synchronizing all measurements, the instrument provides programmable triggers for external digital signals and analog events.Users requiring more than the modules four channels can couple and synchronize up to four instruments, to build a high-performance sound and vibration measurement system, featuring up to 16 analog inputs and four tachometer inputs. The instrument module comes with an extensive software package, including oscilloscope software with FFT and a wide choice of useful software tools and drivers, such as data logger, .NET class libraries and a Win32 software development kit.
