Pulse duration definition

Pulse duration means the time in- crement measured between the half- peak-power points at the leading and trailing edges of a pulse.

Pulse duration means a time in-terval, expressed in seconds, beginning at the first time the pressure ampli- tude exceeds the minimum pressure amplitude plus 10 percent of the dif- ference between the maximum and minimum pressure amplitudes, and ending at the last time the pressure amplitude returns to this value.

Pulse duration means the time increment measured between the halfpeak power points at the leading and trailing edges of a pulse.

More Definitions of Pulse duration

Pulse duration. ’ (Category 6) means the duration of a ‘‘laser’’ pulse measured at Full Width Half Intensity (FWHI) levels.

Pulse duration means the time interval measured between the half-peak power points on the leading and trailing edges of a pulse;

Pulse duration means the duration of a laser pulse, usually measured as the time interval between the half-power points on the leading and trailing edges of a pulse.

Pulse duration. The minimum pulse must be used which permits the whole distance to be seen. This pulse width shall be different for different link distances. The exact value of the pulse used shall be determined by the operator of the OTDR. The following pulse duration figures can be considered indicative: > 0-40 km impulse duration = 2.5 microseconds > 40-80 km impulse duration = 5 microseconds > over 80 km impulse duration = 10 microseconds

IEEE Std 528-2001 (one sigma standarddeviation));
