Using the Marker Feature to Determine the dc Bias Level

During the dc bias sweep, you can use the main marker to determine the dc bias level
(voltage or amperage) at your desired point on the trace. Once you have turned on the dc
bias level monitor feature, the Agilent 4294A preserves the dc bias level monitored for
each measuring point on the trace during the sweep cycle. This allows you to identify the
dc bias level monitored for each measuring point even with the sweep cycle in the hold
state.
NOTE If your sweep parameter is frequency or signal source level rather than dc bias level, the dc
bias level monitored at the first measuring point continues to be displayed in the dc
Voltage/Current Bias Monitor field for all subsequent measuring points because this level
remains constant throughout a non-bias sweep cycle.
Step 1. Start applying dc bias. For more information, refer to "Setting and Applying dc Bias" on
