The spectrum of a pulsed signal in the frequency domain has a sin(x)/x envelope, where x is
proportional to the duty cycle. The spectral components are equidistant with a spacing of
1/PRP. The analyzer measures and displays the pulses in time domain. To be detected
properly, the pulse width must be larger than twice the rise/fall time of the receiver, which
roughly corresponds to the inverse of the IF bandwidth. The figure below shows a rectangular
pulse with a width of 1 μs, measured in a 10 MHz bandwidth. The rise and fall times are
approximately 100 ns.
 Pulse Profile activates pulsed measurements.
 Define Pulse Profile... gives access to the time parameters, the stimulus signal settings, and the
receiver settings for pulsed measurements.
 Show Pulse Profile Settings opens a screen with an overview of the current settings.
