The 4-channel data recorder, DA-21,
is capable of recording acoustic/vibration signals
and various electrical signals in the field.
The recorded data is saved in WAVE format
on SD cards and can be imported into a computer
for waveform analysis and other processing tasks.
It is also possible to expand the number of channels to 8
by connecting two units together.
Signals recorded on the SD card can be analyzed and processed
using the supplied software or the AS-70.
Includes:
AS-70 Viewer: Viewer software for graph display,
level processing, file output, and playback.
DA-21 Instruction Manual: Provided on CD-R.
