Record
A useful function of the ST90 system is it ability to record echo data. Use the raw data recording functionality provided by the ST90 system to save echo data using the *.raw format. You can save the data to the hard disk, or onto an external storage device. The data files can be played back on the ST90 system. The data files can later be deleted, copied or moved to another storage device.

The indicator is red when recording is in progress.
The data files will normally become very large. If you wish to record large amounts of data, make sure that you have enough space on your hard disk. The ST90 system is not provided with unlimited disk capacity. We recommend that you save the data files to an external storage device.
Use the processed data recording function provided by the ST90 system to record processed echo data.
