CHAPTER 3 Settings and Measurement
29 . XY position reference line
Displays when the Position settings and the Vernier settings are visable in the XY digital screen or when
"Origin" is selected by the Quick setting (It is a pink straight line).
In the Range mode, the reference value is 0V (0Vrms).
In the Span mode, the reference value is the center position of the span.
The XY position reference line indicates the display position of the reference value.
For the XY position, the reference position can be set to the left (lower) of the XY graph as 0% and the right
(upper) as 100%. (Be cautious of the difference from the Y-T graph position setting.)
For details of the XY position function, refer to "3.3 Operation Modes" - "(3) XY waveform display" - " XY
position".
30 . XY upper/lower scale
Show the XY upper/lower scale when the Position setting and the Vernier setting are displayed in the XY
digital screen.
The measured values of the left and right edges (X-axis) and the upper and lower edges (Y-axis) of the XY
graph are displayed.
