Examples of APD
When there is no input signal at the measuring receiver, the envelope of the receiver
noise is shown as in
with zero span mode at center frequency fc. The cor-
responding APD response of the receiver noise is shown in
. The ordinate
axis of the APD function displays the probability that the disturbance envelope
exceeds the disturbance level.

If one impulse is received within 1% of time, as shown in
, the APD shows
drastic extension to the right side at the bottom of
, indicating a high distur-
bance level but at low probability. The difference between
and
their peak value (X
max
), it appears dominantly on the abscissa of APD.
