DA-20 is a compact data recorder that provides the user a light weight and high quality
instrument to record various types of electronic signals and waveform data for on-site
measurement of sound and vibration. Measured data are stored on memory card (CF card) in
WAVE format. Stored data can be reproduced as analog signals and output to external signal
processing devices for detailed analysis. The CF card enables easy access to download stored
data processing on PC with optional software line-up.
