
ALC
Enable the ALC function when the DUT is to be driven with constant voltage or constant
current.
ALC : Automatic Level Control
CV : Constant Voltage
CC : Constant Current
Set or check the voltage or current value in advance when specifying the CV or CC.
Otherwise, a signal of unexpected level may be given to the DUT.
When ALC function is enabled,
“
