Auto-scaling the Trace
Auto-scaling for active trace
1. Activate the trace you want to auto-scale.
2. Press Scale
adjusts the scale of the trace so that you can easily examine the
overall characteristics while making all of the data visible within the
graph.
Auto-scaling for all traces
1. Activate the trace you want to auto-scale.
2. Press

Manual Scale Setting (for measurements other than COMPLEX Z-Y)
This section describes how to manually scale the active trace for a
Cartesian-coordinate graph. Note that these procedures do not apply when
the Agilent E4990A is configured to perform a COMPLEX Z-Y measurement
(complex impedance for Trace 1, complex admittance for Trace 2).
Scaling the Trace Based on the Reference Line and Resolution per Division
When the vertical axis is linear, you can scale the trace by first specifying
where to position the reference line and what value to assign to it and then
setting the scale for each division.
1. Activate the trace you want to manually scale.
2. Press
Scale
represents where the reference line should be positioned in relation
to the bottom of the graph. This value ranges from 0 (bottom) and
10 (top). In the preset state, the reference line position defaults to 5,
which means that it is displayed at the center of the graph.
the same color as the corresponding trace.
3. Press
Scale
indicates the reference value, that is, the value of the measurement
parameter that corresponds to the reference line position.
