e-corder 821 (Model ED821) • Turns your PC or Macintosh into a precision data recorder • No programming required – plug and play installation • Powerful on-line and off-line analysis • Continuous recording up to 200 000 samples/s • Independently selectable input gains ±2 mV to ±10 V • 16 bit A/D resolution • Bipolar output for pulse and waveform generation • Trigger input TTL or contact closure • USB 2.0 and 1.1 compliant Description Applications The e-corder 821 is a high performance eight channel data recording and analysis system. It records analog data from a wide variety of transducers and instruments, along with eDAQ Amps and Pods. It features eight programmable input amplifiers, four of which can be configured for differential input. The system can record 16 bit resolution data directly to your PC at speeds of up to 200 000 samples/s via a USB 2.0 compliant interface. A built-in software controlled analog output, provides basic pulse and waveform generation. The e-corder 821 is an ideal data recorder for use with multiple signal sources. Absolutely no programming is required and the powerful on-line and off-line analysis functions allow results to be quickly extracted from the recorded data. The system can be used to replace paper based chart recorders and data acquisition cards in applications such as Materials Testing, Engineering, Vibration Analysis, Sensor Research and Electrochemistry.
