Power User Settings dialog box
The Power User Settings dialog box allows you to configure advanced controls. You can also override the beamlist or processing type during playback. The Ping Rate, Update Rate, and Mode ID are displayed for your information.
How to open
This dialog box is opened from the Advanced menu.

Description
Use the Advanced Controls to configure special processes used during beamforming. Use the Playback Controls to override the fields of recorded “.mmb” data during playback. You can also view detailed system information for the current sonar application.
Details
Advanced Controls
•  RX Amplitude and Phase Correction
This feature allows you to make sure the RX Amplitude and Phase Correction has been successfully written to the Sonar Head during production configuration. Unchecking this box will not apply the correction stored in the Sonar Head to the raw data before beamforming.
•  Azimuth Processing
This feature allows you to make sure the raw data is received properly and to make sure there are no faulty elements in the transducer. Unchecking this box will display the range-compressed raw data in the sonar view with a range vs. element number instead of a range vs. beam angle. The beamforming processing (either the time-domain beamformer or the FFT beamformer) will not be applied.
•  Range Processing
This feature, when used together with Azimuth Processing, allows you to see the unprocessed raw data received directly from the transducer. If the transmit pulse is an LFM pulse, unchecking this box will not apply range compression to the raw data before the beamforming processing.
•  Sidelobe Reduction
This feature allows you to reduce the sidelobe for very bright targets in imaging applications (this feature is not recommended for profiling applications). Sidelobe reduction is especially useful at short ranges when targets are very close.
Note
If automatic sidelobe reduction is enabled in the Display menu, the slider will be greyed out and you can view the automatically-calculated sidelobe reduction ratio. If automatic sidelobe reduction is disabled in the Display menu, you can drag the slider to the right to manually increase sidelobe reduction. On the highest settings you may notice a black line appearing around the same range of the bright target.
Playback Controls
Note
You can also edit the Playback Controls settings in the “PowerUsersInfo.xml” file.
•  Override Beamlist
This feature allows you to replace the beamlist of a recorded “.mmb” file with a new beamlist XML file. The recorded raw data will be beamformed based on the new beamlist. Checking the Override Beamlist box will enable the Beamlist File field. You can type in the beamlist file’s address or click the folder icon to browse for it.
•  Override Processing Type
This feature allows you to switch between the time-domain beamformer and the FFT beamformer for profiling applications. Select the Profiling option when playing back an “.mmb” file (recorded using the Profiling - Fast or Profiling - Bathy sonar applications) to use the time-domain beamformer. Leave this setting as No to use the original processing type for beamforming in post processing.
System Information
•  Ping Rate
The ping rate is determined either by the current sonar application, or calculated based on the network link speed.
•  Update Rate
The update rate is the number of times the sonar view is updated per second. The displayed ping rate may be different from the update rate because the system might be impacted by other processes.
•  Mode ID
All sonar applications have their own unique mode number. The mode number displayed here corresponds to a PRI Sequence ID found in the M3 software database.
