Setting And Applying Dc Bias; Selecting Dc Bias Mode; Setting Fixed Dc Bias Level - Agilent Technologies 4294A Operating Manual

Setting and Applying dc Bias

Follow the steps below to apply dc bias to DUT, regardless of whether you plan to sweep
by dc bias.

1. Selecting dc bias mode

2. Setting fixed dc bias level

When the sweep parameter is not dc bias, select the dc bias mode and then follow the steps
below to set dc bias level.
NOTE Follow the steps shown in "Setting Sweep Range" on page 89 to set the sweep range when
the sweep parameter is dc bias.
Step 1. Press
CURRENT LEVEL
the dc voltage or the current bias level for the segment in the parameter settings located in
the upper left area of the screen.
Step 2. Use the keys or rotary knob of the ENTRY block in one of the following ways to specify a
value for the dc voltage or current bias level.
