KL-710 is a complete data acquisition system that includes both hardware and software for acquisition and analysis of life-science data. The hardware uses the DAQ interface cards from National Instrument. As for the software, it is written in LabVIEW. KL-710 system can use PC, Notebook, or PDA to acquire, analyze or store data. The major software allows you to edit data and control the experiment process appearing on the screen. It performs four general functions: - Control the data acquisition process including the analog input, analog output, digital input, digital output, pulse generation and trigger start. - Perform real-time calculation including the math functions, digital filter, wave analysis, rate detection and power spectrum. - Perform off-line analysis including the statistics, math functions, wave analysis, rate detection and power spectrum. - There are various types for saving data. ? The software, written by Labview, allows users to create their own program.
This equipment is intended for students to learn how to design specific measuring circuits and detect the basic physiological signals with practical operation. Moreover, students can understand electrical characteristics of sensor and transducer explicitly. - KL-720 contains nine modules, including Electrocardiogram Measurement, Electromyogram Measurement, Electrooculogram Measurement, Electroencephalogram Measurement, Blood Pressure Measurement, Photoplethysmogram Measurement, Respiratory Ventilation Detection, Pulse Meter and Body Impedance Detection. - The sensors and transducers used in this equipment include pressure transducer, infrared photocoupler, strain gauge, temperature sensor and surface electrode. - Each module has many test points for changing the frequency bandwidth and amplifier’s gain. Thus students can understand the correlation between physiological signal and each circuit stage.
