Select the display format
From the Display menu, select Display Setup; then open the Appearance tab.
To use
Click one of the buttons to select the display format.
Behavior
YT format is the conventional oscilloscope format:
■
Amplitude appears on the vertical axis as the signal varies over time on the horizontal axis.
■
When you set the vertical position to center the display in YT format, the XY display is at center screen, and each division of
display in YT mode produces a division of display in XY mode.
XY format plots the amplitude of one waveform against the amplitude of another waveform on a point-by-point basis:
■
This format is useful for showing the relationship between two signals, such as current and voltage waveforms that combine
to form an I-V characteristic.
■
When using this format, waveforms appear according to their channel pairings . XY format is a dot-only display, although it
can have persistence.
■
The Vector style selection has no affect when you using XY format.
■
When using this format, the horizontal scale continues to control the time base and the horizontal position continues to
control the portion of the waveform that is shown.
■
Vectors and Intensified Samples selections are not available when using the XY Display Format.
XYZ format compares the voltage levels of the X and Y channel waveform records point-by-point, as in XY format. The displayed
waveform intensity is modulated by the Z channel waveform record. Refer to the table below for channel assignments. XYZ
format is not available on instruments with an ATI channel.

A -5.0 division signal, including position and offset, on the Z channel produces a blank screen; a +5.0 division signal produces full
intensity.
NOTE. Selecting YT or XY only affects the display. The Horizontal, Vertical, and Position knobs (and menus) control the same
parameters except in the Fast Acquisition XY format where the horizontal scale setting is not used.
