Display Colors.
are color-coded to help you identify them easily. The colors are preset
and cannot be adjusted. However, you can select the Monochrome
Color Palette if you prefer to see all the waveforms in high-contrast
black and white.
XY Waveform Triggering.
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.
XY Waveform Scale and Position.
horizontal axis versus channel 3 in the vertical axis, for example, use
these controls to scale and position the XY waveform:
Push the channel 1 button and use the vertical Scale and Position
controls to set the horizontal scale and position of the XY
waveform.
Push the channel 3 button and use the vertical Scale and Position
controls to set the vertical scale and position of the XY waveform.
XY Waveform Restrictions.
functions do not work in the XY display format. All reference
waveforms displayed in XY format must have the same record length,
500 or 10,000 points.
Gated XYZ.
true. Gated XYZ is similar to analog oscilloscope modulated XYZ
mode except that the displayed XY signal is either on or off; there is no
intensity modulation. Gated XYZ is useful for showing constellation
diagrams.
