When REF curve is displayed, the f LINE cursor appears only on the
STORE or VIEW curve. The f LINE cursor is not available in NON STORE
mode.
WINDOW. The WINDOW cursor is displayed as a rectangle and can be used
in any display mode as a reference for visual checks. It can also be used to
measure small signal b (Hfe).
The WINDOW cursor has two modes, depending on whether the base point
is at the top right or bottom left corner. Cursor movement and the cursor
readout display are referenced to this base point.
