• LIN/LOG
LIN/LOG field sets linear or logarithmic sweep mode. In this field, select:
• LINEAR secondary softkey to set linear sweep mode.
• LOG10, LOG25, or LOG50 secondary softkey to set logarithmic sweep
mode. The number specifies the sweep points per decade.
• START, STOP, and STEP
In the START, STOP, and STEP fields, you specify the start, stop, and step
values. The step value is used for the linear sweep mode only.
The following applies to logarithmic sweep mode only:
• STEP field has no meaning, so "------" is shown in the STEP field.
• Start and stop values must be the same polarity.
• If you specify 0 (zero) for the start or stop value, the minimum output value
for the unit is used.
• You specify the number of steps per decade in the LIN/LOG field.
• NO. OF STEP
For the linear sweep mode, the number of steps is calculated from the start, stop,
and step values, and appears in the NO. OF STEP field.
For the logarithmic sweep mode, the number of steps is calculated from the start,
stop, and LIN/LOG values, and appears in the NO. OF STEP field.
• COMPLIANCE
In the COMPLIANCE field, you set the compliance value. If a VSU is used for
the VAR1 unit, this field cannot be set: compliance value is fixed to 100 mA.
• POWER COMP
In the POWER COMP field, you can set a power compliance value for SMUs.
To disable the power compliance function, select the 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.
