• On Time (J-K) - time in milliseconds between
successive -5 dB points of the envelope of the pulsed
signal during which the signal is present, nominally
between 190 and 260 ms
• Off Time (F-J)) - time in milliseconds between
successive -5 dB points of the envelope of the pulsed
signal during which the signal is absent, nominally
between 190 and 260 ms
• Plateau or Pulse Width (C-E) - duration in milliseconds
of the plateau during which the signal is within -1 dB of
its nominal value
• Overshoot (L
ov
) - the level in dB that the signal rises
above the normal “ON” level (SPL on).
