Test head connected to the E4991A and its DUT port
CAUTION
You must not apply either alternate or direct current to the DUT port. Doing this could
cause operational failure. Pay particular attention to whether the capacitor has been
charged. Fully discharge the device under test before connecting it to the test head DUT
port (or test fixture).
CAUTION
Whenever you connect a DUT to or disconnect it from the DUT port for measurement, you
must first turn off the dc bias or set the sweep to the hold state (in sweep hold state, dc bias
is not applied to the DUT). If this step is not taken, the dc bias may destroy the DUT.
