DT9837B, 4 Ch, 24 bit, IEPE 105.4 KHz

The 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
