Gated Sweep Overview
Description The Gated Sweep mode allows a trigger signal
to dictate when the spectrum analyzer can
sweep. This mode is useful for characterizing
signals that are pulsed on and off, such as RF
burst transmissions or for measuring spurious
noise levels between transmission bursts.
Overview 1. The trigger signal must be synchronized to the
period of the input signal (shown as RF burst
below).
2. The start of the gate time is produced from the
positive or negative edge of the trigger signal +
the delay time.
3. The end of the gate time is determined by the
