D&M COUPLE ON OFF When both the data trace and the memory trace are displayed on the screen,
selects performing the scale configurations in this menu for both the data trace
and the memory trace together (couple on) or for each of them separately (couple
off).
1. When the measurement parameter is COMPLEX Z-Y and the display format is COMPLEX.
(Key operation: [Meas] - more 1/3 - more 2/3 - COMPLEX Z-Y, [Format] - COMPLEX)

Key operation:
[Scale Ref]
Softkey
AUTO SCALE For the selected trace (data trace/memory trace of trace A/B), executes automatic
scale adjustment based on the trace data when the key is pressed. The trace is
magnified and displayed so that the graph contains the data of all sweep points,
allowing you to easily grasp the overall characteristics. You can select the data
trace or the memory trace with the SCALE FOR [ ] key in this menu.
FULLSCALE VALUE Sets a scale value of the outermost circle in the polar coordinates display (the
distance between the origin and the outermost circle).
MKR ® REFERENCE
For the selected trace (data trace/memory trace of trace A/B), substitutes the
absolute value of the marker, regardless of the D marker value, into the full scale
value of the outermost circle in the polar coordinates display. As a result, the
marker moves to the full scale line position.
SCALE FOR [ ] When both the data trace and the memory trace are displayed on the screen,
selects the kind of trace to which the scale configurations in this menu are
applied as either data trace [DATA] or memory trace [MEMO].
D&M COUPLE ON off When both the data trace and the memory trace are displayed on the screen,
selects performing the scale setting in this menu for both the data trace and the
memory trace together (couple on) or for each of them separately (couple off).
1. When the measurement parameter is COMPLEX Z-Y and the display format is POLAR.
(Key operation: [Meas] - more 1/3 - more 2/3 - COMPLEX Z-Y, [Format] - POLAR)
