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.
TOP VALUE Sets a value of the top line in the scale graph. This is one of the scale
configurations using TOP VALUE and BOTTOM VALUE.
BOTTOM VALUE Sets a value of the bottom line in the scale graph. This is one of the scale
configurations using TOP VALUE and BOTTOM VALUE.
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 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 not COMPLEX Z-Y and the vertical axis is log display. (Key operation: [Format] - LOG)

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.
SCALE/DIV For the selected trace (data trace/memory trace of trace A/B), sets the amount of
each scale tick. This configuration is applied commonly to the vertical (Y) axis
scale and the horizontal (X) axis scale.
REFERENCE X VALUE Sets a value of the reference line of the horizontal (X) axis (always located at the
center of the horizontal axis).
REFERENCE Y VALUE Sets a value of the reference line of the vertical (Y) axis (always located at the
center of the vertical axis).
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].
