WINDOW cursor
Pressing F4 key (WINDOW) in CURSOR menu
allows the rectangular cursor to appear.
Use of F4 key or pushing FUNCTION knob allows a

→
right
The selected side is displayed.
Rotating FUNCTION knob allows the selected side to
move horizontally or vertically.
The position value of each side is displayed in the area under the menu. In addition, the height
(current value) and width (voltage value) of the rectangular area are displayed.
VERT
−
68.4mA (upper side)
-
−
51.8mA (lower side)
HORIZ
−
8.16V (right side)
-
−
7.96V (left side)
β
(DC current amplification factor) or gm (trans conductance) is displayed under it.
Source setting of step generator: CURRENT
β
=
Height of rectangular area (h) / (STEP current x step No. of cursor position
+
Offset current)
Source setting of step generator: VOLTAGE
gm
=
Height of rectangular area (h) / (STEP voltage x step No. of cursor position
+
Offset voltage)
If the WINDOW cursor is set so that its length is equal to that between steps of curves,
β
or gm at
that position can be measured.
h
Current value at lower side
−
current value at upper side
w
Voltage at left side
−
voltage at right side
