Description

Applications

The e-corder 1621 is a high performance sixteen channel data
recording and analysis system. It records analog data from awide variety of transducers and instruments, along with eDAQ
Amps and Pods. It features sixteen programmable input amplifiers, four of which can be configured for differential input. Thesystem can record 16 bit resolution data directly to your PC at
speeds of up to 200 000 samples/s via a USB 2.0 compliantinterface. A built-in software controlled analog output, provides
basic pulse and waveform generation.

The e-corder 1621 is an ideal data recorder for use with multiple signal sources. Absolutely no programming is required andthe powerful on-line and off-line analysis functions allow results tobe quickly extracted from the recorded data. The system can beused to replace paper based chart recorders and data acquisition cards in applications such as Materials Testing, Engineering,Vibration Analysis, Sensor Research and Electrochemistry.
