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
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 (
unit key (
• Turn the rotary knob (
• 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
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 (
