Data Translation announced the DT9837A, a high performance USB module for sound and vibration analysis. It has four independent 24-bit IEPE (Integrated Electronics Piezo Electric) sensor inputs that are synchronized with a tachometer input to provide data streams matched in time for field or laboratory use. A read-back channel from the analog output guarantees perfect correlation of all signals with the input stream, the output stream, and the tachometer. The different tachometer measure modes allow measurements of the rotation speed as well as precise tachometer pulse phase measurement with a resolution of 37 ns or 0.002° resolution at a rotation speed of 10,000 rpm. This rugged small module is self-powered via the USB connection to a PC or laptop, no external power supply is needed. This makes it suitable for portable measurement applications. Additionally, two modules can be triggered simultaneously for perfectly synched measurements over both. It is priced at $1,795.
