impedance)
Step 5. Press the
REFERENCE Y VALUE
key. The Parameter Setting field in the upper left area of
the screen indicates the reference value currently in effect for the vertical (Y) axis; this
value is a complex value. The reference line for the vertical axis in a complex plane is
stationary in the center of the axis.
Step 6. Use the keys or rotary knob of the ENTRY block in one of the following ways to specify
the reference value for the vertical (Y) axis.
• Enter the desired value with the numeric keys (
[0]
to
[9]
and
[.]
) and then press one of
the unit keys (

,
[M/

,
[k/m]
, or

).
• Turn the rotary knob ( m
