21. Display The display shows captured waveforms using a different color
for each channel. For more information about display modes see
Chapter 3, “Displaying Waveforms,” starting on page 61. Signal detail is
displayed using 256 levels of intensity. For more information about
viewing signal detail see “To adjust waveform intensity” on page 84.
22. Waveform Keys The [Acquire] key lets you set the oscilloscope to
acquire in Normal, Peak Detect, Averaging, or High Resolution modes (see
“Acquisition Modes” on page 227), and lets you turn Realtime sampling off
or on (see page 232). The [Display] key lets you access the menu where
you can select infinite persistence (see page 85), switch vectors on or off
(see page 87), and adjust the display grid (graticule) intensity (see
page 86).
23. Intensity Control Rotate clockwise to increase analog waveform
intensity; counterclockwise to decrease. You can vary the intensity control
to bring out signal detail, much like an analog oscilloscope. Digital channel
waveform intensity is not adjustable. More details about using the
Intensity control to view signal detail are on page 84.
24. Entry Knob The entry knob is used to select items from menus and to
change values. Its function changes based upon which menu is displayed.
Note that the curved arrow symbol above the entry knob illuminates
whenever the entry knob can be used to select a value. Rotate and push
the entry knob to select among the choices that are shown on the
softkeys. More information about the Entry knob is on page 34.
25. Softkeys The functions of these keys change based upon the menus
shown on the display directly above the keys.
26. Back/up The back/up key moves up in the softkey menu hierarchy.
At the top of the hierarchy, the back/up key turns the menus off, and
oscilloscope information is shown instead.
