Select Output\Advanced\Bandwidth\Voltage.
Select either Comp 0, 1, or 2. If desired, enter the
pole frequency in the Frequency field.
Then press Select.
To set the voltage compensation bandwidth:
VOLT:BWID:RANG 0 | 1 | 2
To specify the pole frequency:
VOLT:BWID:LEV 0 | 1 | 2, <frequency>
Current compensation modes allow you to optimize output response time with inductive
loads.
Comp 0 Best suited for longer load leads (higher inductance) with relatively fast programming
response (see Inductance Load Boundary graph).
Comp 1 Optimizes programming speed for DUTs with limited lead inductance. This setting may require
paralleling additional sets of leads to achieve the desired overall lead length.
<frequency> specifies the low-pass corner frequency of a filter applied to the programming signal.
Refer to the previous description under Voltage Compensation modes.
The following table summarizes the effect that the compensation settings have on the CC
Programming Speed Characteristics.
