Waveform Persistence. Turn on waveform persistence to slow the
decay of waveform points. You can set the persistence to a specific
time or to infinite. Infinite persistence keeps all waveform points in
the display until you change a control setting that erases the display.
Display Colors. The channel buttons, waveforms, icons, and readouts
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. 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.
XY Waveform Scale and Position. If you want to display channel 1 in
the horizontal axis versus channel 3 in the vertical axis, for example,
use these controls to scale and position the XY waveform:
H
Push the CH 1 button and use the vertical SCALE and POSI-
TION controls to set the horizontal scale and position of the XY
waveform.
H
Push the CH 3 button and use the vertical SCALE and POSI-
TION controls to set the vertical scale and position of the XY
waveform.
