(not in CW or power sweep). Group delay aperture varies depending on the frequency spacing and point
density, therefore the aperture is not constant in log and list frequency sweep modes. In list frequency
mode, extra frequency points can be defined to ensure the desired aperture.
To obtain a readout of aperture values at different points on the trace, turn on a marker. Then press Avg,
SMOOTHING APERTURE. Smoothing aperture becomes the active function, and as the aperture is varied
its value in Hz is displayed beneath the active entry area.
