Examples of how duration and resolution affect the acquired waveform are shown in the following
figure.
Using the Gating Controls
Gating determines which portion of the acquired waveform is transformed into the frequency
domain. The gate has a position and a width control.
The gate position is the time in seconds from the trigger location to the center 50% position of the
gate interval (see the figure below). The position and width units are seconds.
The gate must reside within the duration interval of the source waveform. If the source waveform
duration is adjusted, and the gate position and width would result in the gate being outside of that
duration, then the gate position or width is set within the limits.
