Keysight E4990A - Selecting the Graph Axis Format

E4990A Help

You can set each measurement parameter without specifying the
active trace or checking its current state.
Selecting Parameter Independently
You can select the measurement parameter for each trace independently.
1. Press Meas > Trace 1, Trace 2, Trace 3 or Trace 4. When you set the
trace 3 or 4, increase the number of trace.
2. 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.

When Using Cartesian Coordinates
Unless the E4990A is configured to perform a COMPLEX Z-Y measurement
(complex impedance for Trace 1, complex admittance for Trace 2), it
displays measurement results in a Cartesian-coordinate graph whose
horizontal and vertical axes indicate the sweep and measurement
parameter values, respectively. Use the following procedure to select the
vertical axis format for a Cartesian-coordinate graph:
1. Activate the trace for which you want to set the axis format.
2. Press the Format key to display the Format menu.
3. Select the desired vertical axis format by pressing the appropriate
key, Linear|Log.
The horizontal axis format is automatically determined
based on the selected sweep type.
When Using Complex Parameters (COMPLEX Z-Y)
When the Agilent E4990A is configured to perform a COMPLEX Z-Y
measurement (complex impedance for Trace A, complex admittance for
Trace B), use the following procedure to select the graph axis formats:
1. Activate the trace for which you want to set the axis format.
2. Press Format > Complex Format.
3. Select the desired graph axis format by pressing the appropriate key,
Complex|Polar.
