Making a Measurement
Sampling Measurements
To Define Measurement Units
1. Press Chan key in the PAGE CONTROL key group.
2. Select CHANNEL DEF primary softkey.
3. In the MEASUREMENT MODE area, select SAMPLING secondary softkey.
4. In the VNAME column, enter a unique name for voltage variable. For example,
enter Vce for collector-emitter voltage. If channel does neither V force nor V
measurement, you can omit VNAME.
5. In the INAME column, enter a unique name for current variable. For example,
enter "Ic" for collector current. If channel does neither I force nor I
measurement, you can omit INAME.
6. In the MODE column, select:
• V secondary softkey for voltage output mode (SMU, VSU, and PGU, and
grounded voltage measurement mode of VMU).
• I secondary softkey for current output mode (SMU).
• VPULSE secondary softkey for pulsed voltage output mode (PGU).
• COMMON secondary softkey for circuit common mode (SMU and GNDU).
• DVOLT secondary softkey for differential voltage measurement mode
(VMU).
7. In the FCTN column, select CONST secondary softkey for all source units.
VNAME and INAME
You can use VNAME and INAME in user function definitions or for analysis on the
GRAPHICS/LIST screens. These names must be 6 or less alphanumeric characters.
First character must be alphabet character.
To disable a unit
Move the pointer to the row of the unit, then select the DELETE ROW secondary
softkey. The settings in the row are deleted.
