Smart echo level test

The function allows you to test the behavior of the transmitter in a real tank environment
without raising the level. During the test, a virtual surface echo is superimposed onto the
radar signal, and the transmitter will output a level corresponding to the echo position.
The test verifies the integrity of the signal processing, and can be used to test the alarm
limits in the host system, output of the transmitter, and transmitter configuration (for
example the upper/lower range values).
