Recording echo data
Use the raw data recording functionality provided by the ME70 to save echo data using the *.raw format. The data files can be copied or moved to an external storage device, or to another computer on the network. You can keep the recorded files for future reference, training purposes and calibration. The recording is controlled by the Record function.
Prerequisites
Before you start data recording, make sure that you have defined where to store the files. To define which disks and folders to use to save the data files, use the File Setup page. File Setup is located on the Setup menu under Output. Alternatively you can find File Setup in the Operation menu under Record.If you wish to save your recorded data on an external hard disk, make sure that it is connected to the computer.
Context
You can save and recall echo information using the following methods and formats:
•  Bitmap images (containing the full ME70 screen capture) are saved whenever you select Screen Capture on the top bar. Each screen capture you make is saved in .jpg format on the Processor Unit hard disk. The Screen Captures tab on the bottom bar opens a dedicated viewer that allows you to open these images. In the viewer you can also open the file folder on the Processor Unit hard disk. You can copy, rename or delete the image files.
•  Use Record on the Operation menu to record raw data. To play back data, select Operation and then Replay mode. This mode allows you to play back previously recorded data. In Replay mode the ME70 system is not able to transmit ("ping"). For this reason, the ME70 system is inactive during playback.
Note
If you wish to record large amounts of data, make sure that you have enough space on your hard disk. Unless your computer is equipped with a very large disk, we recommend that you save the data to an external storage device.
