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 4294A is configured to
perform a COMPLEX Z-Y measurement (complex impedance for Trace A, complex
admittance for Trace B).
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.
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 POSITION key. The Parameter Setting field in the upper left area
of the screen displays a value that represents where the reference line is currently
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.
Step 4. Use the keys or rotary knob of the ENTRY block in one of the following ways to specify
the position of the reference line.
• 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 (
m

m) until the desired value is set.
• Press the step keys ([][¯]) to set the desired value.
