Option 4285A-001 (internal DC bias)
Maximum DC bias current when the normal meas-
urement can be performed is 100 mA.
DC bias settling time
When DC bias is set to ON, add 5 ms to the meas-
urement time. This settling time does not include
the DUT charge time.
Sum of DC bias settling time plus DUT (capacitor)
charge time is shown in the following figure.

(capacitor) charge time
