Short Impedance Check
Upon completion of the open impedance check, carry out a short impedance
check with the fixture set for the SHORT state.
Step 1.
At the DUT measuring position, connect an appropriate shorting bar with the
electrode to secure the fixture for the SHORT state. (See
Figure 3-16 on
page 37
).
Step 2.
Make the settings for the 4291B as follow.
Step 3.
Under this condition, measure Ls at 100MHz and 1GHz, separately.
Step 4.
Confirm that the Ls value is within the typical range shown in
Table 6-7
Short-impedance Measurement Repeatability Check
Repeat short impedance measurement to check for the repeatability of
measurement.
Step 1.
Upon completion of the short impedance check, disconnect the shorting bar
and connect it again with the electrode.
Step 2.
Under the same measuring conditions as given above, measure Ls again at
100MHz and 1GHz, separately.
Step 3.
Confirm that the Ls value is within the typical range shown in
Table 6-7
.
