Each single element in the ME70 transducer is connected to a dedicated channel on a transceiver board. Each of these channels is provided with a transmit/receive
switch, which is used to protect the sensitive receiver electronics during transmission.
Due to a voltage divider implemented in the transceiver board hardware, and the software functionality provided on the circuit
board, the signals in and out of the transmit/receive switch can be monitored.

During transmission, the receiver electronics measure the voltage or current of the transmitted pulse. |

During receiving, the receiver electronics measure the voltage of the received signal. |
