STEP 8. Measuring DUT and Analyzing Measurement
Results
After performing calibration and compensation, the measurement results are displayed on
the screen when the DUT is connected to the test fixture. If you obtain the correct trace,
you can analyze the measurement results by using the marker and the equivalent circuit
analysis function. This section describes the procedure by using only the mouse and
keyboard.
Applying dc Bias (Option 001)
When selecting "(4) Dc Bias (Current) Characteristics of Ls-Q (Option 001)" on page 58 in
"STEP 2. Setting Measurement Conditions", follow these steps to apply dc bias. For
settings of the dc bias source level and dc bias limit, refer to Chapter 3, "Setting
Measurement Condition" in the E4991A Operation Manual.
WARNING
Never touch the DUT or the electrodes of the test fixture while dc bias is applied.
