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.

Examples of Pulse duration in a sentence

• Pulse duration in seconds can be set separately for each relay in “Setup-Input/Output-Relay Outputs”.For locally activated relays a text description of the controlling parameter is displayed rather than buttons.

• Pulse duration of the MBES is very short relative to the naval sonars.

• Pulse duration in seconds can be set separately for each relay in “Setup-Input/Output-RelayOutputs”.For locally activated relays a text description of the controlling parameter is displayed rather than buttons.

• The maximum frequency should be 20 Hz or more.• Pulse duration: The average pulse duration should not exceed 20 ns• Pulse to Pulse stability: ≤0.75% or better (at high as well as at low discharge voltages) for very low energy variations between subsequent laser pulses.• Beam Dimension (V X H): ~24 x 10mm2• Beam divergence: 3 x 1 mrad2 or better• Laser Beam Pointing Stability: 50µrad or better• Cooling: Air-cooled only• Laser Tube: Metal Ceramic technology.

• So, for reliable protection against transients, a certain degree of “overdesign” must be considered.Therefore the following figures for overvoltage in 230 V power lines can only be taken as rough guidelines:■ Amplitude up to 6 kV■ Pulse duration 0.1 μs to 1 msWhere varistors are operated directly on the line (i.e. without series resistor), normally the type series S20 should be chosen.

• Pulse duration decreases if number of cycles in a pulse is decreased or if frequency is increased.

• Pulse duration from scanning exposure variable and dependant on content and measurement location.

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
