VAR2 parameters
In this column, you set up the output parameters for the secondary sweep unit. UNIT
and NAME are defined on the CHANNELS: CHANNEL DEFINITION screen.
SWEEP MODE and LIN/LOG fields are fixed to SINGLE and LINEAR.
• START, STEP, and NO. OF STEP
In the START, STEP, and NO OF STEP fields, you specify the start value, step
value, and number of steps. The stop value is calculated from these values, and
is shown in the STOP field.
• COMPLIANCE
In COMPLIANCE field, you set compliance value. If a VSU is used for VAR2
unit, this field cannot be set: compliance value is fixed to approximately 100
mA.
• POWER COMP
In POWER COMP field, you can set power compliance value for SMUs. To
disable power compliance function, select OFF secondary softkey.
VAR1' parameters
In this column, you set up the output parameters for the synchronous sweep unit.
This VAR1' table is displayed only when VAR1' is set in the FCTN field on the
CHANNELS: CHANNEL DEFINITION screen.
UNIT and NAME are defined on CHANNELS: CHANNEL DEFINITION screen.
• OFFSET and RATIO
In the OFFSET and RATIO fields, you specify the offset and ratio values. The
offset and ratio values determine the VAR1' value as follows:
VA R 1 ’ output = VAR1 output ´ ratio + offset
• COMPLIANCE
In COMPLIANCE field, you set compliance value. If a VSU is used for VAR1'
unit, this field cannot be set: compliance value is fixed to 100 mA.
• POWER COMP
In the POWER COMP field, you can set the power compliance value. To disable
the power compliance function, select OFF secondary softkey. If an SMU is set
to VPULSE or IPULSE mode and if the SMU is set to VAR1', you cannot set
power compliance for the VAR1' SMU.
