Frequencies and intervals
The diagrams below show the bandwidth of the different types of Marport sensors and intervals
you must respect when adding other sensors.
Figure 2: PRP sensors (e.g. Catch sensor, Trawl Speed, Spread sensor...)
Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.9-40kHz
and 40-40.1kHz.
Figure 3: NBTE sensors (e.g. Speed Explorer, Trawl Explorer, Catch Explorer, Door Sounder)
Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.8-40kHz
and 40-40.6kHz.
Figure 4: HDTE narrow band mode
Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.8-40kHz
and 40-41kHz.
Figure 5: HDTE wide band mode
Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.8-40kHz
and 40-42.6kHz.
