Record RAW function
Record RAW allows you to record the unprocessed echo data received by the transducer. 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. You can keep the recorded files for future reference, training purposes and calibration.

How to open
This function is opened from the Operation menu.
Description
Use the raw data recording functionality provided by the ST90 system to save echo data using the *.raw format. By means of the Replay function you can later play back the recorded file(s). This may prove useful if more a detailed study of the data is requested. You can also use the file(s) to experiment with the operational settings, as this will help you to gain more experience. The amount of data you can record is only limited by the size of your storage media.
The recording is controlled by the Record RAW function.
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.
The Output dialog box on the Operation menu allows you to set up the recording parameters. To define which disks and folders to use to save the data files, select File Setup.
Ways to start and stop recording
You can start and stop data recording in several ways.
