1. When the measurement parameter is not COMPLEX Z-Y and the vertical axis is in the linear or percentage format.

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 entire data, allowing you

to easily grasp the overall characteristics. You can select the data trace or the

memory trace with the SCALE FOR [ ] key in Table B-28, “Scale reference

(Scale Ref) menu (1-2/2),” on page 373.

AUTO

SCALE/DIV For the selected trace (data trace/memory trace of trace A/B), sets a value for the

scale per division in the axis for measured value. This is one of the scale

configurations using REFERENCE POSITION, REFERENCE VALUE, and

SCALE/DIV.

SCAL <value>

REFERENCE POSITION For the selected trace (data trace/memory trace of trace A/B), sets the position of

the scale reference line. The position of the reference line is indicated by a value,

assuming that the lowest line of the graph is 0 and the highest line is 10. This is

one of the scale configurations using REFERENCE POSITION, REFERENCE

VALUE, and SCALE/DIV.

REFP <value>

REFERENCE VALUE For the selected trace (data trace/memory trace of trace A/B), sets a reference

value (the value of the scale reference line). This is one of the scale

configurations using REFERENCE POSITION, REFERENCE VALUE, and

SCALE/DIV.

REFV <value>

MKR ® REFERENCE For the selected trace (data trace/memory trace of trace A/B), substitutes the

absolute value of the main marker into the reference value (the value of the scale

reference line) regardless of the value of the D marker. As a result, the marker

moves to the reference line position.

MKRREF

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.

TOPV <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.

BOTV <value>

Key operation: [Scale Ref] - more1/2

Softkey Function GPIB command

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 Table B-27, “Scale

reference (Scale Ref) menu (1-1/2),” on page 373 are applied from the data trace

[DATA] or the memory trace [MEMO].

SCAF {DATA|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 Table B-27, “Scale reference

(Scale Ref) menu (1-1/2),” on page 373 for both the data trace and the memory

trace together (couple on) or for each of them separately (couple off).
