Step 15. Select the dc bias mode.
Step 16. Press the
return
key to return to the segment edit menu (2/3). Note that the dc bias mode
currently selected is displayed in the key label
[ ]
of the
BIAS MODE [ ]
key.
NOTE
The unit for the value in the cell located in the segment row and the dc bias level column
(BIAS) is modified according to the selected mode. Remember that you should verify
whether the mode is constant/non-constant voltage/current by using the key label of the
BIAS MODE [ ] key.
Step 17. When a voltage source (non-constant or constant voltage mode) is selected for the dc bias
mode, press the
DC BIAS VOLTAGE
key. This will display the current setting for the dc
voltage bias level value for the segment in the parameter settings located in the upper left
area of the screen.
Step 18. Use the keys or rotary knob of the ENTRY block in one of the following ways to specify a
value for the dc voltage bias level.
• Enter the desired value with the numeric keys (
[0]
to
[9]
,
[.]
, and
[-]
) and then press the
unit key (
[G/n]
,
[M/ m ]
,
[k/m]
, or
[ ´ 1]
).
• Turn the rotary knob (
m m m m
) until the desired value is set.
• Press the step keys ([

]) to set the desired value.
The setting above will add a new value for the dc voltage bias level to the cell located in
the segment row and the dc bias column (BIAS) of the list sweep table in editing mode.
Step 19. When a current source (non-constant or constant current mode) is selected for the dc bias
mode, press the
DC BIAS CURRENT
key. This will display the current setting for the dc
current bias level value for the segment in the parameter settings located in the upper left
area of the screen.
Step 20. Use the keys or rotary knob of the ENTRY block in one of the following ways to specify a
value for the dc current bias level.
• Enter the desired value with the numeric keys (
[0]
to
[9]
,

, and
[-]
) and then press the
