Echo strength (3.2.11.4.)
Displays the strength ( in dB above 1 μV RMS) of the echo which was selected as the
measurement echo.
Index Transducer
Values Range: 0 ... 99 (Read only)
Noise average (3.2.11.5.)
Displays the average ambient noise (in dB above 1 μV RMS) of a noise profile after each
measurement.
The noise level is a combination of transient acoustic noise and electrical noise (induced into
the transducer cable or receiving circuitry). For more information, see Noise problems
(Page 286).
Noise peak (3.2.11.6.)
Displays the peak ambient noise (in dB above 1 μV RMS) of a noise profile after each
measurement.
Echo time filtered (3.2.11.7.)
Displays the time, in ms, from the transmission of the pulse, to when it is processed.
Index Transducer
Values Range: 0.0 ... 9999 milliseconds (Read only)
Related Echo time raw (3.2.11.8.) (Page 263)
Echo time raw (3.2.11.8.)
Displays the time, in ms, from the transmit pulse to the processed echo.
