Impulse response representation (Echo representation) (optional)

By means of the impulse response representation, it is possible to measure echoes in the transmission path or multiple path reception. The green line (on the left in the screen to dB) represents the received used carrier. The other (red) lines are echoes. For multiple path reception, pre-echoes can also occur, if an unwanted transmitter has a shorter distance to the receiver as desired.

With the button „dist. km/µs,“ you can switch the measurement between running time and distance.

With the cursor buttons, ◄►, you can move the yellow marker for measuring the distance or the time and the level of reflection.
