Then press Select.
Current compensation
The current compensation provided is suited to handle a wide, range of total lead and DUT inductance
with a relatively fast programming response (see
impact of load lead inductance, paralleling additional sets of load leads to lower the net inductance
can help, especially if load lead lengths are long.
<frequency> - specifies the low-pass corner frequency of a filter applied to the programming signal.
Refer to the previous description under Voltage Compensation modes for a description of use case
tradeoffs of changing the <frequency> setting.
The following table summarizes the effect that the compensation settings have on the CC
Programming Speed Characteristics for all models.

The CC programming small signal bandwidth characteristic at -3dB is 3.5 kHz for all models.
Front Panel Menu Reference
Select Output\Advanced\Bandwidth\Current.
There is only one compensation bandwidth.
If desired, enter the pole frequency in the Frequency
field. Then press Select.
Set the Output Turn-On/Turn-Off Mode
The turn-on/turn-off setting only applies when the unit is operating in voltage priority
mode. In current priority mode, the turn-on/turn-off behavior is set to High
impedance.
