Quick Reference
The time reference is indicated at the top of the display grid by a small hollow
triangle (
∇
). Turning the Horizontal scale knob expands or contracts the waveform
about the time reference point (
∇
).
The trigger point, which is always time = 0, is indicated at the top of the display
grid by a small solid triangle (
▼
).
The delay time is the time of the reference point with respect to the trigger.
Turning the Horizontal position (
) knob moves the trigger point (
▼
) to the left or
right of the time reference (
∇
) and displays the delay time.
The Acquire menu lets you select the time mode (Normal, XY, or Roll), enable
Zoom, set the time base fine control (vernier), and specify the time reference.

Zoom
The Zoom window is a magnified portion of the normal time/div window. To turn
on (or off) Zoom, press the
zoom key (or press the
[Acquire]
key and then the
Zoom
softkey).

Channel 1 is the X-axis input, channel 2 is the Y-axis input. The Z-axis input (Ext Trig) turns the trace
on and off (blanking). When Z is low (<1.4 V), Y versus X is displayed; when Z is high (>1.4 V), the
trace is turned off.
Measuring the phase difference between two signals of the same frequency with the Lissajous
method is a common use of the XY display mode (see the "XY Display Mode Example" description at
www.keysight.com/find/xy-display-mode
).
