Signal analyzer DT9837 series

laboratorypowernoise

The DT9837 Series of USB dynamic signal analyzers provide highly accurate measurements for portable sound, vibration, and force response measurements. Features include an A/D per channel, up to one analog output, up to one tachometer, and IEPE signal conditioning for direct sensor measurements. The DT9837 Series high-accuracy dynamic signalacquisition modules are ideal for portable noise,vibration, and acoustic measurements. Four, 24-bit, IEPE(ICP®) sensor inputs are synchronized with a tachometerinput (depending on model) to provide data streams thatare matched in time, for field and laboratory use. Theserugged, compact modules are USB powered, makingthem ideal for portable measurement applications. • Runs on USB Power – ideal for portable applications • Four Simultaneous, 24-bit Delta-Sigma A/Dconverters for high resolution measurements • Support for IEPE (Integrated Electronic Piezoelectric)inputs, including use of a 2 mA or 4 mA currentsource and AC or DC coupling • Up to 105.4 kS/s sample rate per channel • Input range of ±10 V with software-selectable gainsof 1 and 10 for an effective input range of ±10 Vand ±1 V, respectively • For DT9837C modules only, 1 Hz high-pass filter onanalog input subsystem • Return the value of tachometer counter 0 in theanalog input data stream, to measure the periodor frequency of the tachometer input signalsynchronously with analog input measurements • For the DT9837A and DT9837B modules only, theability to read the value of tachometer counter 1in the analog input data stream, allowing you toprecisely correlate tachometer measurements withanalog input measurements
