Window expansion
Window expansion is used for amplifying a segment of waveform so as to check details. The
window expansion time base setup cannot be slower than the setup of the main time base. In the
window expansion region, a selection region can be moved leftwards and rightwards by the
horizontal [POSITION] knob or enlarged and reduced by revolving the [SEC/DIV] knob. The
window expansion time base has higher resolution relative to the main time base. The smaller the
window expansion time base is, the higher the horizontal expansion multiple of the waveform is.
Carry out the following steps to observe details of local waveform:
1. Press [HORI MENU] to display the "HORIZON" menu.
2. Press "Window Ctr" menu.
3. Revolve [SEC/DIV] (to regulate the size of the window) and the horizontal [POSITION] (to
regulate the position of the window) to select the window of the waveform to be observed. The
expansion time base cannot be slower than the main time base.
Press the "Minor Window" button after the window is setting well.
