DT9837A Analyzer Overview

Digilent's DT9837A is a USB-based dynamic signal analyzer with four simultaneous 24-bit IEPE sensor inputs, 52.7 kS/s sample rate, one tachometer input, and one 24-bit analog output. It features built-in IEPE signal conditioning for direct measurements from sensors like accelerometers and microphones.

Features unique to the DT9837A are the ability to read the value of tachometer counter 1 in the analog input data stream, allowing you to precisely correlate tachometer measurements with analog input measurements. It also supports reading analog output values in the analog input data stream, allowing you to correlate input and output values. In addition, the DT9837A has a RJ45 synchronization (LVDS) connector for synchronizing acquisition on up to four modules.

Software support for the DT9837A includes QuickDAQ, an out-of-the-box application for data logging, visualization, and signal generation. Two QuickDAQ upgrades are available and offer FFT analysis functions. Drivers are included for the most popular applications and programming languages including Visual C++, Visual C#, Visual Basic.NET, DASYLab, LabVIEW, Linux, and MATLAB.

The DT9837 Series

Digilent's DT9837 Series high-accuracy dynamic signal acquisition modules are ideal for portable noise, vibration, and acoustic measurements. Four, 24-bit, IEPE (ICP) sensor inputs are synchronized with a tachometer input (depending on model) to provide data streams that are matched in time, for field and laboratory use. These rugged, compact modules are USB powered, making them ideal for portable measurement applications.
