Hydrophone Number of the hydrophone corresponding to its port on the receiver.

SNR
3
Noise Level You will have better performance with the following levels:
4
Period of recep­ This is the interval between 2 signals that have been well received. It should
tion be 1 to 6 seconds for NBTE signals. For PRP signal, it should correspond to the
telegram intervals.
5
Detection qual­ Only for sonar data: quality of the uplink communication between the sensor
ity and the vessel. Best is 100%, worse is 50%.
6
Filter rejection Only for sonar data: level of filtering applied to the echogram in order to display
a better image in Scala2, best is 0%. A high percentage of filtering means a bad
signal reception.
7 Status If the status displays a message other than No error, it means there is a commu­
nication or measurement issue. Contact Marport support.
Learn how to solve common problems.
• SNR is correct above 20 for PRP sensors, above 10 for NBTE sensors.
• Below these levels, SNR is low, causing a discontinuous signal
• Active wideband hydrophone with high/low gain: below -100 dBV
• Active narrowband: NC-1-04 below -80 dBV / NC-1-07 below -100 dBv
• Passive hydrophone: below -110 dBV
