WebPulse Width. Pulse width is the time from the 50% threshold of a pulse's rising edge to the 50% threshold of the next falling edge. Pulse width: up to 1,000,000 s (see restrictions below). The default pulse width is 100 μs. The minimum pulse width is 16 ns on the 33500 Series and 5 ns up to 4 Vpp or 8 ns up to 10 Vpp on the 33600 Series. WebIf the signal is higher, it means you have fixed it and gotten your 90° pulse width value without having to redo the pulse width calibration experiment. 2) Run the experiment with …

WebMost manufacturers specify dead zones at the shortest available pulse width and on a -45 dB reflection for singlemode fibers and -35 dB for multimode fibers. For this reason, it is important to read the specification sheet footnotes since manufacturers use different testing conditions to measure the dead zones—pay particular attention to the pulse width … WebFrom Figure 2-1, the resting time is the difference be- tween the pulse repetition time (the reciprocal of the pulse repetition frequency) and the pulse width. Rest Time = 1/8000 Hz - 1.5 x 10-6 s = 1.24 x 10-4 s = 124 ms A pulsed radar has a duty cycle of .016. If the resting time is 380 ms, what is the pulse
