The E4990A preserves the graph axis formats, scale settings, data and memory trace contents, and trace definitions for each parameter (for example, Ls) unless it is turned Off or reset to its preset state. This feature makes it easy to examine the DUT from various perspectives by switching among a number of measurement parameters. For detailed information on configuring the settings that control how the E4990A displays measurement results, refer to the following sections:

You can set each measurement parameter without specifying the active trace or checking its current state.

You can select the measurement parameter for each trace independently.

Press Meas > Trace 1, Trace 2, Trace 3 or Trace 4. When you set the trace 3 or 4, increase the number of trace.
Select the desired measurement parameter for the trace.

Vdc and Idc can be selected when the sweep type is set at either DC Bias or Log DC Bias.
