Bottom DescriptionSide
XY Display
Off (YT) Turns off an XY display.
Triggered XY Turns on triggered XY display.
Gated XYZ Displays XY signals when
Z-channel signal is above a set
level. Only available on 4-chan-
nel instruments.
Ch1 (X)
Versus
Sets Ch2, Ch3, or Ch4, as Y
versus Ch1 as X.
Ref1 (X)
Versus
Sets Ref2, Ref3, or Ref4 as Y
versus Ref1 as X.
Gated By
Sets Ch2, Ch3, or Ch4 as Z
channel (gate) source, and
gating channel threshold level.
Color Palette
Normal Selects the color display.
Monochrome Sets all waveforms to high-con-
trast black and white.
XY Waveforms. For XY waveforms, channel 1 or Ref 1 is
displayed in the horizontal axis. Use the Vertical POSI-
TION and SCALE controls to adjust the horizontal
position and size of the XY waveform.

Another channel or reference waveform is displayed in
the vertical axis. Use the Vertical POSITION and
SCALE controls for that channel to adjust the vertical
position and size of the XY waveform.
XY Waveform Triggering. The XY waveform is triggered
so you can synchronize periodic input signals to the XY
waveform. This feature is useful when only one part of
the period contains valid information that you want to
see in the XY format. Set the time base and trigger
location to acquire just that part of the period.
When you want to see the complete period of the signals
regardless of the time base setting, set the trigger source
to an unused channel and the trigger mode to Auto.
Gated XYZ. Displays XY signals only when the Z (gating)
channel is true. Gated XYZ is similar to analog oscillo-
scope modulated XYZ mode except that the displayed
XY signal is either on or off; there is no intensity modu-
lation. Gated XYZ is useful for displaying constellation
diagrams.
The general purpose knob sets the Z-channel threshold
level.
