How Does It Work?#

Vector Oscilloscope plots two incoming signals against each other on an X/Y display, making stereo phase, Lissajous figures, and geometric waveform relationships easy to see.

Quick Overview#

• X and Y inputs drive the horizontal and vertical axes.
• The display has persistence, intensity, zoom, rotation, gain, and offset controls.
• You can freeze the view, swap axes, invert either axis, show a center grid, or enable auto gain.

Inputs#

Port	Type	What It Does
X	Multi	Horizontal axis input.
Y	Multi	Vertical axis input.

Vector Oscilloscope has no outputs. It is display-only.

Controls Reference#

Control	Values	Default	Behavior
Zoom	0.25..4	1	Scales both axes together.
Glow	0.2..2	1	Changes line intensity.
Rot °	-180..180	0	Rotates the display.
Tail	0.05..0.98	0.82	Sets persistence / decay of older traces.
X Gain	0.25..4	1	Scales the X axis only.
X Pos	-1..1	0	Offsets the X axis.
Y Gain	0.25..4	1	Scales the Y axis only.
Y Pos	-1..1	0	Offsets the Y axis.
Freeze	Off, On	Off	Holds the current frame.
Swap	Off, On	Off	Exchanges the X and Y axes.
Invert X	Off, On	Off	Flips the X axis.
Invert Y	Off, On	Off	Flips the Y axis.
Show Grid	Off, On	On	Shows or hides the center crosshair.
Auto Gain	Off, On	Off	Applies automatic level scaling before drawing.

Behavior Notes#

• If only one axis is patched, the other axis is treated as zero.
• Freeze can hold a valid frame even after live data stops changing.
• The status label can show LIVE, FROZEN, FROZEN NO DATA, or NO SIGNAL.

Typical Uses#

• Check stereo phase and width.
• Compare two oscillators or modulation sources as Lissajous figures.
• Inspect how rotation, inversion, and axis scaling change a shape before recording or exporting visuals.
