CHAPTER 3 Settings and Measurement
The differences in XY digital display operation are as follows.
Mode
RANGE
SPAN
In RANGE mode, the relationship between the FS range displayed by the AMP setting and the V/DIV range
displayed on the XY digital display are as follows. In addition, the VERNIER setting range in each range is
as shown in the following table.
FS range
20mV
50mV
100mV
200mV

5V

Since the RANGE affects the hardware operation (amplifier sensitivity), it cannot be altered during capturing
or replaying.
The RANGE setting is common to the RANGE setting of the Y-T graph.
The display amplitude of the waveform is determined by the range and X-Y dedicated position, and Vernier
settings, without span setting of Y-T graph.
In SPAN mode, the SPAN can be changed within the same range as the Y-T graph.
Set the SPAN in RANGE/SPAN display of XY digital display with ease. In addition, details can adjusted using
the AMP menu setting or DISP menu setting.
It is common to use span setting of Y-T graph.
3-40
RANGE/SPAN
Use the keys to change
the V/DIV range.
The V/DIV range cannot be
changed during replay.
Use the keys to change
the Span width.
The Span width cannot be
changed during replay.

POSITION
Position reference point is 0V
or 0Vrms.
Position reference point is the
center point of the span.
