Acquiring and Displaying Waveforms
3–28 TDS 684A, TDS 744A, & TDS 784A User Manual
NOTE. TDS 700A models only: This subsection assumes you are using Normal
acquisitions mode and gives display settings for this mode. If you select InstaVu
acquisitions, procedures for making Style, Format, and Readout display settings
differ and some selections are not permitted. See Using InstaVuT Acquisition
Mode, on page 3–43, for setup differences and Incompatible Modes on page 3–45.
To bring up the Display menu:
Press DISPLAY ➞ Settings (main) ➞ Display (pop-up).
The Display menu allows you to adjust the style, intensity level, graticule, and
format features described below. The Color menu allows you to alter color
settings for various display components such as waveforms and text. To find
more information on color, see Customizing the Display Color on page 3–33.
TDS 684A only: Press DISPLAY ➞ Style (main) ➞ Vectors, Intensified
Samples, Dots, Infinite Persistence, or Variable Persistence (side) (See
Figure 3–17.)
TDS 700A models only: Press DISPLAY ➞ Mode (main) ➞ Normal
(pop-up) ➞ Style (main) ➞ Vectors, Intensified Samples, Dots, Infinite
Persistence, or Variable Persistence (side)
Vectors style displays vectors (lines) between the record points.
Dots style displays waveform record points as dots.
Intensified Samples style also displays waveform record points as dots. However,
the points actually sampled are displayed in the color labeled “Zone” in the
Display Colors menus.
In addition to choosing Intensified Samples in the side menu, the oscilloscope
must be interpolating (equivalent time must be off for TDS 700A models) or
Zoom must be on with its horizontal expansion greater that 1X. See Interpola-
tion on page 3–18; see Zooming on Waveforms on page 3–37.
Variable Persistence style accumulates the record points on screen and displays
them only for a specific time interval. In that mode, the display behaves like that
of an analog oscilloscope. You enter the time for that option with the keypad or
the general purpose knob. Record points are also displayed with colors that vary
depending on the persistence of the point. See Choose a Palette on page 3–33.
Infinite Persistence style accumulates the record points until you change some
control (such as scale factor) causing the display to be erased.
