A menu is presented that allows
the selection of three window types (see
6-12).

impulse
levels are the same as low pass impulse
levels.
Choose one of the three window shapes listed in
6-12. Or you can use the knob to select
any windowing pulse width (or rise time for a step stimulus) between the
values. The

A window is activated only for viewing a time domain response, and does not affect a
displayed frequency domain response. Figure 6-72 shows the typical effects of windowing on
the time domain response of a short circuit reflection measurement.
