The DEWE-3100-DSA-8 puts top-level DSA performance capabilities into our unique "DEWE-NOTEBOOK" - the DEWE-3100 model. The result is an all-in-one CoreDuo computer with a flip-up touchscreen, battery operation for more than 2 hours, and eight simultaneously sampled 24-bit resolution inputs ... with IEPE/constant current signal conditioning on each input channel. You can also set each input to be a voltage input if needed - or activate the constant current sensor supply to power your IEPE/ICP™ sensors. There's an additional ninth input for tach/RPM signals, allowing advanced angle-based measurement features like order tracking, and more.

The 8 accelerometer/microphone inputs are robust 24-bit inputs capable of sampling up to 200 kS/s PER CHANNEL. Data are streamed right into the DEWE-3100's hard drive, so recording time is extremely long given today's hard drive storage capacities. As an example, recording all eight channels at 200 kHz consumes 22 GB per hour ... so with today's larger and larger drives you have plenty of recording time!

Hammer, Shake Table, and RPM workThe included software provides not only continuous acquisition via DEWESoft, but also the FRF functionality for frequency response function testing. Modal capabilities include both triggered and free-run modes. Use triggered mode when you are using an impulse hammer to excite a broad range of frequencies with distinct "hits" at preselected places on the structure. DEWE-FRF shows you the results of each hit, and provides also hit-reject functionality.

Use the free-run mode for shake table testing. DEWE-FRF includes strong yet easy to use analytical capabilities for all your model testing applications.

...and that's an order!
If you are testing engines, motors, flywheels, or anything rotating, then the order tracking function is especially important to you. The ninth input on the DEWE-3100-DSA-8 is exactly for a tach pulse input. During recording you can display your data in "orders" of the incoming rpm.
