When a DUT is connected to the measurement contacts, the setting current
value is different from the actual current passing through the DUT. For normal
measurement taken by applying the signal current through a device, refer to
“DC Bias Current Isolation” on page 97.
Figure 3-7 DC bias signal current
Setting limits for DC bias and test signal level
When both the DC bias and the test signal level are set under the following
conditions, the amount of DC bias plus the test signal level is limited to the
values listed in
Table 3-19
• Option 001 is installed.
• The DC Bias key on the front panel is set to ON.
