850-164692 / Rev.B

Colour scale

The Colour scale view is normally located on the left side of the Echogram view.

The Colour scale view visualizes the mapping of echo strength into one out of 12 colours, light blue for weak signals and dark brown for strong signals. Basically, each discrete colour represents a 3 dB range of echo signal strength implying that the next colour is selected every time the echo strength doubles. However, as the number of colours can differ, and dedicated colour schemes can be used, this is not necessarily correct

A high numeric TVG value displays weak echo signals properly while the stronger signals saturate into dark brown colour. A low numeric value displays strong echo signals properly. Weak signals below the lower limit of the colour scale are not displayed (the display background colour is used).

If you place the cursor inside the view, a small yellow label will appear to give you a detailed readout of certain information. The Tooltip dialogue defines which information that will be shown.

If you click the right mouse button with the cursor position within this view, a dedicated shortcut menu will appear. If you click the middle button, the Colour Scale dialogue box opens.

Data recording and playback

Background

You can set up the echo sounder to record unprocessed transducer signals (sample data) and external sensor information onto files. These files contain the necessary information to reconstruct the situation during the real survey. The echo sounder program reads these files during replay.

Recording

Prepar

ations

The recording is prepared as follows.

1 Open the Output menu, and select File. 2 Observe the Output File dialogue open. 3 Select the tab Directory and push the Browse button if

you wish to change the direcory to which the files are stored.

4 Press the Raw Data tab to define how the raw data is to

be recorded:

- Save raw data: Start/stop recording of raw data.

- Range: Select the depth range to be recorded. This

range, referring to the transducer face, is independent of any other range settings in the echo sounder.

- Echogram data: This is user defined excerpts of the

processed sample data (pixel data), ie the backscatter value of the targets. The echograms are stored as time tagged datagrams in separate files.

5 If necessary, limit the maximum size of a single file.

- The current file will be closed and a new file will be

automatically generated when either the Max vessel

distance or the Max. file size limit is reached.

6 Click OK to exit the dialogue.

Start and stop recording

Use either the Toolbar buttons or the Save raw data check box in the File Output dialogue to start or stop recording of data.

Note on size of stored raw data

The size of the raw data files stored depends on several user selections. From these selections you may estimate approximately the total amount of raw data stored in a given time period for each installed channel using the following equation:

X = B bytes per sample * (8*R)/(c*tau) samples per ping * M ping per sec * 24 * 3600 sec per day

Simrad ER60 Operator manual

850-164692 / Rev.B

where:

X = Total amount of stored raw data in bytes for one channel B = 4 (Given by the resolution of the sample data) R = Selected range in meters (User defined) c = Sound speed in water in meters per sec (User defined) tau = Pulse duration in seconds (User defined) M = Ping rate in ping per seconds (User defined)

Thus, you can affect the amount of stored raw data by changing e.g. the range, pulse duration, and ping rate settings.

Playback of a single file

The playback is started as follows: 1 Open the Operation menu, and select Replay.

- Observe the Replay dialogue.

2 Select the single file to be played.

- If no file is listed, click the Add button to select. Note

that only one replay file can be listed if this single file shall be replayed.

3 Click Loop if you wish to loop through the selected file

endlessly.

4 Click OK. 5 Click the Play buttonintheToolbar.

During playback, the ping rate is not limited by the speed of sound in water. Hence, it is possible to select a higher ping rate than during normal operation.

Playback of multiple files

The playback is started as follows: 1 Open the Operation menu, and select Replay.

- Observe the Replay dialogue.

2 Click the Add button to select playback files

- You can place any number of files in the list in the

Replay dialogue.

3 Click the first file you wish to play back. 4 Click Loop if you wish to loop through the the files

endlessly.

5 Click OK. 6 Click the Play buttonintheToolbar.
