Manually Scaling the Active Trace for a COMPLEX Z-Y Graph
Manually Scaling the Active Trace for a COMPLEX Z-Y
Graph
This section describes how to manually scale the active trace when the Agilent 4294A is
configured to perform a COMPLEX Z-Y measurement (complex impedance for Trace A,
complex admittance for Trace B).
Scaling the Active Trace for a Complex Plane
When your graph is a complex plane, you can manually scale the active trace by specifying
the reference values for the vertical and horizontal axes as well as the scale per division.
Step 1. Activate the trace you want to manually scale.
Step 2. Press the
[Scale Ref] key to display the Scale Reference menu.
Step 3. Press the
REFERENCE X VALUE key. The Parameter Setting field in the upper left area of
the screen indicates the reference value currently in effect for the horizontal (X) axis; this
value is a real value. The reference line for the horizontal axis in a complex plane is
stationary in the center of the axis.
Step 4. Use the keys or rotary knob of the ENTRY block in one of the following ways to specify
the reference value for the horizontal (X) axis.
• Enter the desired value with the numeric keys (
[0] to [9] and [.]) and then press one of
the unit keys (
[G/n], [M/m], [k/m], or [´1]).
• Turn the rotary knob (

• Press the step keys ([][¯]) to set the desired value.
