Sweep Measurements
Defining Measurement Conditions
To Define Measurement Units
Press Chan front-panel key to define the measurement units. CHANNELS:
CHANNEL DEFINITION screen is displayed.
1. MEASUREMENT MODE:
Select SWEEP secondary softkey for sweep measurement.
2. VNAME:
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.
3. INAME:
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.
4. MODE:
Select one of the following softkeys:
• V : Voltage output (for SMU, VSU, and PGU).
V : Grounded mode voltage measurement (for VMU).
• I : Current output (for SMU).
• VPULSE : Pulsed voltage output (for SMU and PGU).
• IPULSE : Pulsed current output (for SMU).
• COMMON : Circuit common (for SMU and GNDU).
• DVOLT : Differential mode voltage measurement (for VMU).
5. FCTN:
Select one of the following softkeys to set the output function:
• CONST : Constant output function (for SMU, VSU, and PGU).
• VAR1 : Primary sweep output function (for SMU and VSU).
• VAR2 : Secondary sweep output function (for SMU and VSU).
• VAR1' : Synchronous sweep output function (for SMU and VSU).
