4.6 Graph display mode
The basic graph display mode settings are explained in this section. For more information on the functions,
refer to "
5.5 Graph display
".
■ Setting the display unit
To set the unit used when displaying measurement data, select either gain-phase or impedance. The graph
display differs according to the display unit that is set. Use
【
Graph
】 －
[DISPLAY UNIT] to select [GAIN]
or
[IMPEDANCE]
.
■ Setting the display mode
Use
【
Graph
】 －
[DISPLAY MODE] to select what is to be displayed on the X axis, Y1 axis, and Y2 axis
of the graph. The items that can be selected vary according to the analysis mode setting. The possible
graph display combinations are shown in the following table. If settings other than shown in the table are
used, nothing at all is displayed on the graph. "LIN" represents a linear axis scale and "LOG" represents a
logarithmic axis scale. "
✔
" or "
✘
" symbol indicates whether linear or logarithmic axis setting is
possible.

If the analysis mode is (CH1/CH2) or (CH2/CH1), gain is displayed as reciprocal data (reverse polarity
for dB units) and phase is displayed as reverse polarity data.
