When you move the pointer to a field on a setup screen, you can fill in the field by
entering characters or selecting a softkey. See figure below. This figure shows an
example which sets the current output mode for SMU2. Line above the primary
softkeys is called as the data entry field. The line displays the value of the entry field
the pointer specifies, or is used to enter the value.

Screen Operation
Data Input or Edit
Option fields
When pointer is in an option field, selectable input items for field are displayed on
secondary softkeys. You select desired softkey. The item appears in the field.
For example, when pointer is in the MODE field for SMU2 as shown in the above
figure, V, I, VPULSE, IPULSE, COMMON, and DELETE ROW softkeys appear in
secondary softkey area. Then select one you desire.
In the screens except for the CHANNEL DEFINITION screen, if pointer is located
in a field that requires a variable name, all available variable names are displayed on
secondary softkeys. So you can select desired variable name by using a secondary
softkey. Available variable names are names you already set up as measurement
variables or user function variables. If more than six variable names are available,
MORE secondary softkey appears, which display more available variable names.
Comment and Name fields
When the pointer is located in a comment or name field, you input the desired
characters by using the ENTRY front-panel key group. You press the desired
characters. The characters appear in the data entry area.
For name fields, you can enter alphanumeric characters. For comment fields, you
can also enter non-alphanumeric characters. You can enter uppercase or lowercase
alphabet characters by using blue and green front-panel keys. You can enter special
(non-alphanumeric) characters by using the green front-panel key.
If a comment or name is already entered in the field, it appears in the data entry area.
You can edit it using Edit front-panel keys.
After editing or entering the comment or name, press the
enter the name or comment into the field at the pointer location.
Enter front-panel key to

Green front-panel key usage
You can use the green front-panel key to enter special (non-alphanumeric)
characters, which are printed in green above the keys.
The green key action is momentary. That is, after you press the green key, only the
next keystroke is effective. For example, to enter “#$”, press the green key, 0, green
key, and 1.
The green key mode has special functions for entering data, as shown in the
following table.
The front-panel green key can also be used to perform dump (Plot/Print key), knob

MEASUREMENT
MODE
NOTE Application setup data in internal memories
MEASUREMENT MODE field sets measurement mode to sweep measurement
mode, sampling measurement mode, or quasi-static CV measurement mode. In this
field, select:
• SWEEP secondary softkey to set sweep measurement.
• SAMPLING secondary softkey to set sampling measurement.
• QSCV secondary softkey to set quasi-static CV measurement.
To change settings (except for system screen group) to default initial settings, select
DEFAULT MEASURE SETUP secondary softkey.
MEM secondary softkeys indicate that setup or measurement result data is in the
internal memory. When you turn on the 4155C/4156C without a diskette or network
disk, the following secondary softkeys are displayed:
MEM1 M
B-Tr VCE-IC measurement setup data for bipolar transistor Vce-Ic
characteristics.
MEM2 M
FET VDS-ID measurement setup data for FET (field effect transistor) Vds-Id
characteristics.
MEM3 M
FET VGS-ID measurement setup data for FET (field effect transistor) Vgs-Id
characteristics.
MEM4 M
DIODE VF-IF measurement setup data for diode Vf-If characteristics.
M on the softkey means measurement setup data.
Select softkey to get the desired application measurement setup data. This
minimizes the time for setting up the measurement conditions.

This column lists all the units that are installed in the 4155C/4156C.
VNAME.
VNAME field assigns a variable name for voltage that will be forced or measured.
You can use this name as a reference on the other screens. If channel does neither V
force nor V measurement, you can omit VNAME.
In this field, enter a name by using the keyboard or front panel keys. where,
• VNAME must be 6 or less alphanumeric characters. First character must be
alphabet character.
• Name must be different from other names.
The DELETE ROW softkey deletes the VNAME, INAME, MODE, FCTN, and
STBY entries for the unit. Unit is disabled.
NOTE To switch the unit definitions
To switch the VNAME, INAME, MODE, FCTN, and STBY assignment for units,
do as follows:
1. Position pointer in top field of VNAME column. CHANNEL ASSIGN
secondary softkey appears.
2. Select CHANNEL ASSIGN softkey. Pointer moves to the top field of UNIT
column.
3. Use arrow keys in the MARKER/CURSOR key group to move pointer to
desired row.
4. Select the secondary softkey of the desired unit. The selected unit appears at the
pointer.
Perform steps 3 and 4 until you assign units as desired. Make sure that the same unit
is not assigned to multiple rows. Then, select the EXIT CHANNEL ASSIGN
softkey.

INAME.
INAME field assigns a variable name for current that will be forced or measured.
You can use this name as a reference on the other screens. If channel does neither I
force nor I measurement, you can omit INAME.
In this field, enter a name by using the keyboard or front panel keys. where,
• INAME must be 6 or less alphanumeric characters. First character must be
alphabet character.
• Name must be different from other names.
The Select DELETE ROW softkey deletes the VNAME, INAME, MODE, FCTN,

MODE.
You define an output mode for SMUs, VSUs, PGUs, and GNDU, and measurement
mode for VMUs. When the pointer is located in this column, allowable modes
appear in the secondary softkey area. You select a softkey to set a mode. The

where,
• You can set multiple CONST in a channel setup.
You cannot set multiple VAR1, VAR1', or VAR2 in a channel setup.
• VAR2 and VAR1' are available when VAR1 is set.
• The output modes of VAR1 and VAR1' must be same. That is, the MODE setting
for both must be set to a voltage mode, or both must be set to a current mode.
For example, you can set VAR1 to V and VAR1' to VPULSE.
• For QSCV measurements, only one V mode SMU can be set to VAR1.
STBY.
STBY field specifies which channels output source values in the standby state.
• If STBY is set to ON, the unit forces a specified output value when in the
standby state.
• If STBY is blank, the unit outputs 0 V in the standby state.
For details about the standby state, see User’s Guide: Measurement and Analysis.
where,
• If both PGUs are set to VPULSE, the STBY setting of both PGUs must be the
same.
• For STBY=ON channel, SERIES RESISTANCE setting must be 0 ohm.
