Pinpoint
The tone of the acoustical signal changes its frequency only in a LR-window
which ranges from one decade below the Trigger level 1 up to one decade above
the Trigger level 1. Below the window the tone is constantly
low
, above the window
it is constantly high.
Example: The Trigger level 1 is 4×10

mbar l/s up to 4×10
-6
mbar l/s.
