A transducer or transceiver has a number of sectors used for transmitting signals. The number and geometry of the sectors will determine the beam type and how to calculate the angles. BeamType is a parameter in EK80 which identifies transducer/transceiver type and geometry.

Bit 8 - 10 = Number of Complex per Samples |
Angle data for Complex and Angle are processed differently. Make sure you use the right processing for the power data received.
